Is this PDF signer really free?

Yes. 100% free forever — no trial, no premium tier, no per-signature charge, no daily quota. Sign as many PDFs as you want. Ad-supported so it stays free for everyone. Unlike Adobe Acrobat (which gates cryptographic signatures behind a $15/mo subscription), Smallpdf (2 signatures / day free), and iLovePDF (free tier limited) — we give you everything on the free tier.

Do I need an account?

No. No signup, no login, no email, no captcha, no credit card. Open the page, drop your PDF, sign, download.

Is my PDF uploaded to a server?

No. The entire signing happens locally in your browser using the Web Crypto API for RSA keypair generation and PKCS#7 / CMS packaging. Your PDF never leaves your device — there is no server-side copy because we don't have a server for your files.

Is my signature or private key sent anywhere?

No. Your signature image, drawing, or typed name stays in browser memory. If you upload a .p12 / .pfx certificate, it's parsed locally — never transmitted. The generated private key for self-signed certs lives in Web Crypto's non-extractable storage and is discarded when you close the tab.

What's the difference between an electronic signature and a digital signature?

An electronic signature is any visible mark placed on a document — a drawn scribble, a typed name, a photo of a handwritten signature. It looks like a signature but has no cryptographic proof. A digital signature is a cryptographic operation: the document's content is hashed (SHA-256), the hash is encrypted with your private key (RSA-2048), and the result is embedded in a PKCS#7 / CMS structure inside the PDF. Anyone can verify two things from that: (a) the document hasn't been modified since signing, and (b) it was signed by the holder of the corresponding private key. Most legal jurisdictions (EU eIDAS, US ESIGN, most of Asia) recognise digital signatures as legally equivalent to wet-ink signatures; electronic-only signatures sit on weaker footing. Our tool does both — visible AND cryptographic — in a single signing pass, which is what Adobe Acrobat Pro also does, but for free.

How do I sign a PDF for free?

Drop your PDF on the page above. The editor opens with the Certify modal pre-selected. Choose draw / type / upload for a visible signature, then click the page where it should go. Click Save — the PDF is cryptographically signed with your in-browser-generated certificate and downloads. Entirely free, entirely local, no signup. Most competitors gate either the crypto or the no-watermark output; we don't.

How do I add a signature to a PDF?

Same flow. Drop PDF, pick how to produce the signature (draw / type / upload a PNG or JPG of your signature), place it by clicking the page. Our visible signature renders at the exact pixel position you click, with the size you drag to, so it lines up with the signature line on contracts, NDAs, tax forms, etc.

Are PDF signatures legally binding?

In most jurisdictions, yes, with nuance. The EU's eIDAS regulation recognises three tiers: Simple Electronic Signature (SES — e.g. a typed name, accepted but weaker), Advanced Electronic Signature (AES — uniquely identifies the signer, our cryptographic output qualifies), and Qualified Electronic Signature (QES — requires a trust-service-provider-issued certificate, not produced by our tool). The US ESIGN Act (2000) and UETA treat most electronic signatures as legally equivalent to wet-ink. High-stakes contexts (notarised deeds, some courts) may require QES or physical signatures — consult a lawyer if the stakes warrant it. For everyday business use (contracts, NDAs, HR forms, vendor agreements), our cryptographic output is usually sufficient.

What is PKCS#7 / CMS?

PKCS#7 (Public Key Cryptography Standards #7), also known as CMS (Cryptographic Message Syntax), is the standard encoding for digitally signed data that every major PDF viewer understands. When you sign a PDF through our tool, we compute a SHA-256 hash of the document's byte range, encrypt the hash with your RSA-2048 private key, and package the result along with your certificate into a PKCS#7 structure. That blob is embedded inside the PDF's /Sig field. Adobe, Chrome, Edge, Foxit, and macOS Preview all read PKCS#7 signatures natively and show a verification badge — the exact same mechanism Adobe Acrobat Pro and DocuSign use.

Do the signed PDFs work in Adobe Acrobat?

Yes. Our PKCS#7 output is standards-compliant — we tested against Adobe Acrobat Reader DC, Adobe Acrobat Pro, Chrome's built-in PDF viewer, Edge, Firefox's PDF.js, macOS Preview, and Foxit Reader. All show a verification badge. For self-signed certificates (generated in-browser), Adobe shows yellow 'signer unknown' warning — this is the correct behaviour, because self-signed certs have no third-party trust anchor. To get a green badge, upload a .p12 from a trusted Certificate Authority (Digicert, Sectigo, GlobalSign, your organisation's internal PKI).

How do I sign a PDF with a .p12 / .pfx certificate?

In the Certify modal, click 'Use existing certificate'. Upload your .p12 or .pfx file, enter the password if it has one. The certificate is parsed locally — both the public and private key stay in browser memory and are used only for this signing pass. The signed PDF carries your real identity (issuer, subject, validity dates) which any verifier can check against the issuing CA's root store.

What if I just want a visible signature without the crypto?

Pick the 'Visible only' option in the Certify modal. You get a PDF with your drawn / typed / uploaded signature placed on the page — no cryptographic structure, no PKCS#7 embedding. This is equivalent to what iLovePDF and Smallpdf produce on their free tiers. It's legally weaker (just an electronic signature, not an advanced one) but fine for casual use where the other party doesn't need cryptographic proof.

Can multiple people sign the same PDF?

Yes, sequentially. Sign once and download. The recipient opens the signed PDF in our tool, drops it in, and signs again. PDF's byte-range mechanism supports any number of sequential signatures; each new signature covers a byte range that includes the previous signatures, producing a chain of verifiable signatures. (Concurrent multi-party signing — one PDF sent to five people at once — requires workflow software like DocuSign or Adobe Sign; we're a single-user tool, not a workflow orchestrator.)

Does it work offline?

Yes, once the page has loaded. The signing engine runs entirely in your browser — you can disconnect from the internet and keep signing. Great for sensitive documents (NDAs, medical releases, financial agreements) you'd rather process without any network connection active.

Can I sign a PDF on my phone?

Yes. Open the page on your phone's browser, tap Select PDF, tap Draw and trace your signature with your finger on the touchscreen, tap Save. Works on iPhone Safari, iPad, Android Chrome. Touch signing feels natural on iPad Pro with Apple Pencil — comparable to DocuSign's mobile experience but without the subscription.

Can I sign a password-protected PDF?

If the PDF is owner-locked (opens without a password), yes. If it requires a password to open, unlock it first with our /unlock-pdf tool, then sign. Our unlocker is also 100% local — the password never leaves your device.

What about timestamped signatures (RFC 3161 TSA)?

Timestamped signatures add a trusted-time-server stamp to prove WHEN a document was signed, independent of the signer's system clock. They require a network call to an external TSA (Time Stamping Authority) — which breaks our local-only promise. We don't ship timestamping today. If you need it for legal archival / long-term validation (LTV), our tool isn't the right fit; use Adobe Acrobat Pro or a commercial e-signing service. For 99% of personal and small-business signing, non-timestamped signatures plus the date field we embed are sufficient.

Is this the best free PDF signer?

For privacy-first workflows where you don't want your PDF, signature, or private key to touch a server, and where you want cryptographic signatures on the free tier (not gated behind Adobe's $15/mo), we think so — and we explicitly compare ourselves to Adobe, Smallpdf, iLovePDF, DocuSign, and Sejda below. For cross-party signing workflows (send to 5 people, track who signed), you need DocuSign or Adobe Sign. Pick the tradeoffs that match your actual use case.

Me pehea te haina i te PDF mo te kore utu

1. Whakataka to PDF

Toia te PDF ki runga i te rohe taka i runga, ka paato ranei ki te tirotiro. Ka tuwhera aunoa te ētita me te Certify modal i tohua i mua - kaore he whakatere i roto i nga tahua, kaore he rapu mo te taputapu haina.

2. Tuhia, patohia, tuku ake ranei to waitohu

Ko te Certify modal e tuku ana i nga huarahi e toru ki te waitohu e kitea ana: te tuhi me to kiore, trackpad, maihao ranei i runga i te mata pa; patohia to ingoa ki te momotuhi waitohu pono; tuku ake ranei he PNG / JPG o to hainatanga. Ko enei e toru he rite nga hua ka kitea - whiriwhiria ko wai te mea tino maori mo koe.

3. Taapirihia te take, te waahi, me te ra

I runga i te PDF 2.0 spec, ko nga hainatanga cryptographic e mau ana i te take (hei tauira, "Ko ahau te kaituhi"), te waahi (hei tauira "Berlin, Tiamana"), me nga waahi o te ra. Ka kite nga kaitirotiro i enei ki te taha o te mana crypto. Ka whakakiia e matou te ra; whakakiia te toenga ki te hiahia te horopaki.

4. Tuhia te waitohu me te haina

Patohia ki hea i runga i te wharangi kia taka te tapawha waitohu kitea. Tōia ki te huri i te rahi. Pāwhiritia Tiaki. Ka whakaputahia e matou he matua RSA-2048 hou + tiwhikete haina-whaiaro i roto i to tirotiro, ka tatau i te hash SHA-256 o te awhe paita tuhinga, ka kohia te putunga raraunga kua hainatia PKCS#7, ka whakauru ki te PDF. Ko nga konae kua hainatia ka tango tonu.

He aha te Kaitohu PDF tino pai rawa atu

100% o te rohe — karekau he whakaurunga o te tūmau

Ko to PDF, ko to hainatanga kua tuhia, ko to tiwhikete kua tuku ake, ko to taviri tūmataiti - kaore tetahi e pa ki te tūmau. Whakatauritea: Adobe, Smallpdf, iLovePDF, DocuSign, me Sejda ka tuku katoa i nga mea katoa. Ina he kirimana hainatia te tuhinga, he NDA, he whakahoki taake, he tuku rongoa ranei, he mea nui ake i nga waahi katoa o te ipurangi.

Tuturu tuhi, taumata kore utu

Ka hoatu e te Smallpdf me te iLovePDF he waitohu kitea i runga i o raatau taumata kore utu - he tuhi i runga i te whaarangi kaore he tohu tohu. He "waitohu hiko", he ngoikore te ture. Ka hoatu e matou he waitohu matihiko PKCS#7 / CMS mo te kore utu, he rite tonu te paerewa Adobe Acrobat Pro e whakamahia ana (kei muri i te ohaurunga $15/mo ki reira).

Tiwhikete haina-whaiaro tonu

Ko te nuinga o nga rerenga hainatanga cryptographic e tono ana i te tiwhikete kua tukuna i mua. Ka whakaputahia e matou he takirua matua RSA-2048 hou me te tiwhikete X.509 i hainatia i roto i to kaitirotiro ma te API Tukutuku Crypto — kore tatūnga. Tukuna mai to .p12 / .pfx o mua mena ka hiahia koe ki te whakawhirinaki-tuatoru; ki te kore ko te tiwhikete haina-whaiaro ka nui mo te whakamahi whaiaro me nga rerenga mahi pakihi iti.

Ko te tauira awhe paita a PDF e tautoko ana i te maha o nga waitohu raupapa; ka hipokina e ia hainatanga hou nga mea o mua, ka puta he mekameka manatoko. Ka whakahaerehia e ta maatau etita te hainatanga me te kore e whakakore i te hainatanga o mua.

Tino Whakakore, mo ake tonu atu

Kaore he whakamatautau, kaore he taumata utu, kaore he utu mo ia hainatanga. Adobe Acrobat Pro he $15/mo; Ko DocuSign Whaiaro he $15/mo; Smallpdf Pro he $12/mo. Ko enei katoa ka tuku ake i to konae, me tono ranei he ohaurunga mo te hainatanga cryptographic. E tautokona ana matou me te kore utu mo ake tonu atu.

Kaore he kaute, kaore he imeera

Me timata tonu te haina. Kaore he hainatanga, kaore he hopu imeera, kaore he kaari nama.

Ka mahi tuimotu

Kia utaina te ētita ka taea e koe te momotu mai i te ipurangi me te haina tonu. He pai mo nga kirimana tairongo, NDA, me nga tuhinga putea whaiaro.

Waitohu Hiko vs. Waitohu Mamati — He aha te mau tonu

Waitohu hiko (SES — Maama)

Ko nga tohu ka kitea i runga i te tuhinga matihiko: he ingoa kua patohia, he tuhi tuhi, he waitohu waituhi-makuku kua karapahia, he pouakataki "E whakaae ana ahau". I whakamanahia e te ture i roto i te nuinga o nga mana whakahaere mo nga pakihi o ia ra (EU eIDAS SES taumata, US ESIGN / UETA, UK Electronic Communications Act) engari he ngawari ake te whakataetae mena ka whakakahore te kaihaina i muri mai i te hainatanga — karekau he tohu tohu mo te tangata nana te tohu. Ko ta maatau aratau "kitea anake" ka puta tenei.

Waitohu hiko teitei (AES)

EU eIDAS regulation tier 2. Me (a) te tautuhi motuhake i te kaihaina, (b) kei raro i te mana o te kai hainatanga, (c) te kite i te raweke i muri i te hainatanga, (d) ka hanga ma te whakamahi i nga raraunga ka taea e te kaihaina te pupuri i raro i tana mana motuhake. Ko ta maatau whakaputanga cryptographic (PKCS#7 i runga i te SHA-256 me te RSA-2048 me tetahi taviri motuhake i hangaia i te rohe i roto i te rokiroki Tukutuku Crypto kore-tangohia) ka tutuki nga paearu e wha - ka taea e koe te kii i te mana AES mo te PDF i hainatia ki konei.

Waitohu hiko tohu (QES)

Te taumata ture eIDAS a EU 3. AES me tetahi tiwhikete whaimana mai i tetahi Kaiwhakarato Ratonga Kaitiaki (TSP) i runga i te rarangi whirinaki a EU, me tetahi taputapu hanga hainatanga whaimana (HSM, kaari atamai ranei). Ko te QES he rite tonu ki te hainatanga waituhi maku puta noa i te EU katoa. Kare matou e whakaputa i te QES na te mea karekau e taea e nga rerenga tirotiro-anake te whakatutuki i te whakaritenga taputapu hanga waitohu-a-pumau - me whai taputapu hainatanga motuhake, kapua HSM ranei. Mena kei te tono to keehi whakamahi i te QES (nga kirimana kua tohua, etahi umanga kua whakaritea), me hiahia koe ki te Adobe Waitohu, DocuSign EU Qualified, he TSP rohe ranei.

Ture US (ESIGN / UETA)

Ko te US Federal ESIGN Act (2000) me te kawanatanga UETA whakatamarikitanga he rite ki te ture te nuinga o nga hainatanga hiko ki te waituhi-makuku — me te kore he kaupapa a te EU. Kia whai mana te hainatanga: (a) me whakaae nga taha e rua ki te haina ma te hikohiko, (b) me whai whakaaro te hainatanga, (c) me pupuri nga rekoata. He mahinga enei katoa; ka tutuki ta tatou putanga ki a ratou. Ko etahi momo tuhinga motuhake kua whakairohia (he wira, he take ture-whanau, etahi tuhinga a te kooti) — tirohia to kawanatanga.

For you signing your own documents — contracts you received, vendor agreements, NDAs, tax forms — we cover the exact same cryptographic capability for free, without uploading anything.

Ko wai ka tohu PDFs penei?

Ka haina nga kirimana korekore

Ka tukuna e te kaihoko he SOW, he kaipupuri ranei. Ka haina koe, crypto-stamp, whakahokia mai. Karekau he tukuake ki DocuSign, kaore he imeera "whakamatautau kore utu", kaore he ohaurunga Adobe — a he kaha ake te hainatanga i te tuhinga JPG na te mea kei te tautokohia e te PKCS#7 crypto.

HR me nga puka mahi

Tukuna nga reta, nga NDA, nga paatete whakauru, nga W-9, nga puka pupuri taake. Kare e tika ana te tukuake ki te waahi hainatanga kore utu. Waitohu a rohe, whakahokia mai ma te imeera.

Nga whakaputanga rongoa me nga puka HIPAA

Nga mana kua hainatia mo nga rekoata rongoa, kereme inihua, puka tuku whakamatautau ranei. Ko nga ihirangi kua hipokina e te HIPAA kaua e tukuake ki te tūmau a te tangata ke. Nga take hainatanga-a-rohe anake.

Nga reta ture

Ko nga reta whakauru, ko nga whakaaetanga whakataunga, ko nga whakapuakanga, ko nga korero oati. I te wa e piri ana te mana, kaua te tuhinga e waiho i to taputapu i te wa e haina ana. Ka tiakina e to maatau rohe.

Nga hoko whare me nga kirimana riihi

Nga kirimana riihi, whakatikatika riihi, whakaaturanga rawa. Waitohu me te hoki mai me te kore rehita mo tetahi atu turanga hainatanga. Ka whiwhi te hoa taurite ki te PDF kua hainatia-whakamana ka taea e ratou te whakatuwhera ki tetahi kaimakitaki.

Nga puka a te kawanatanga me te taake

Puka IRS (W-9, 1099), tono a te kawanatanga, tuhinga manene. He maha nga tari e whakaae ana ki te PKCS#7 kua hainatia PDFs. Ko te hainatanga o te rohe ka karo i te tuku ake i nga tuhinga tuakiri tairongo.

Kaituhi me nga kaipupuri mana

Waitohua he mahi matihiko hei whakamatau i te kaituhi i tetahi wa motuhake. Ko te hainatanga PKCS#7 + tohu wa kei roto i te PDF kua hainatia he rekoata pumau tonu, ka mauhia e to kii motuhake.

Nga whakataunga a te poari whakahaere

Ko nga meneti a te poari, nga whakataunga whakaaetanga, nga karaati whiringa kararehe. Ko te tautoko mekameka maha-kaitohu ka taea e nga kaiwhakahaere te haina raupapa me te kore tuku whakamua i te PDF ma te kapua tuatoru.

Puranga tuhinga roa

Waitohuhia he PDF nui i tenei ra me te hainatanga tohu tohu-raa. Rokiroki i te rohe. I nga tau i muri mai, ka taea tonu e te tangata kei a ia te konae te manatoko i hainatia e te kaipupuri o to taviri tūmataiti, a, kaore ano kia whakarereketia mai i tera wa. (Mo nga rerengamahi whakamana-waa-roa me nga tohu waahi pono, tirohia te waahanga FAQ i runga i te LTV.)

Waitohu PDF ki iPhone, Android, Mac, Windows, me Chromebook

Ka mahi to taatau haina PDF ki ia taputapu me te tirotiro hou - Windows, Mac, Linux, Chromebook, iPad, iPhone, me Android. I runga i te iPad Pro me te Apple Pencil, ko te tuhi i to hainatanga he rite tonu ki te tono pūkoro a DocuSign, haunga te ohaurunga me te tango i te tukunga ake. Karekau he whakaurunga taupānga, karekau he monomai, karekau he mana whakahaere. Kia utaina te wharangi ka taea e koe te momotu mai i te ipurangi me te haina tonu - ka rere nga mea katoa i te rohe ma te API Tukutuku Crypto.

Me pehea te mahi hainatanga PDF i runga i te tirotiro tirotiro?

Ka paato koe i te Tiaki, ka whakaputahia he takirua matua RSA-2048 hou i roto i to kaitirotiro ma te whakamahi i te API Tukutuku Crypto (crypto.subtle.generateKey) — kei te noho te taviri tūmataiti i roto i te rokiroki kore-tangohia, kaore e taea te kaweake. Ka hangaia e matou he tiwhikete X.509 i hainatia me to ingoa hainatanga i tohua. Kua reri te PDF me te waahi waahi /Sig i roto i te mara /AcroForm. Ka tatauhia e matou he hash SHA-256 o te awhe paita o te tuhinga haunga te kaipupuri waahi. Kua hainatia te hash me to taviri tūmataiti ma te crypto.subtle.sign (RSA-PKCS1-v1_5 me SHA-256). Hangaia e matou he hanganga PKCS#7 / CMS Waitohu Raraunga kei roto te waitohu, to tiwhikete, te wa hainatanga, me etahi take/tauwāhi metadata. Ko te putunga PKCS#7 he DER-whakawaeherehia, kua mau ki te mara /Sig o te PDF. Ka tikiake te kōnae. Ko ia kaitirotiro PDF hou (Adobe, Chrome, Edge, Foxit, Arokite, Firefox) ka panui i te hanganga PKCS#7 i te tuwhera, ka tatau ano i te haki tuhinga, ka manatoko i te hainatanga ki te tiwhikete whakauru, me te whakaatu i te tohu whakaū. Ka rere nga crypto katoa i roto i to kaitirotiro - karekau he tūmau, karekau he tukuake, karekau he waea waea.

Pātai Auau

Me pehea taku haina i te PDF mo te kore utu?

Whakatakahia to PDF ki te wharangi o runga. Ka tuwhera te ētita me te aratau Certify i tohua i mua. Tuhia, patohia, tukuake ranei to waitohu. Patohia te wharangi hei tuu. Pāwhiritia Tiaki. Kore utu, rohe, kore tohuwai.

Me pehea taku taapiri i tetahi waitohu ki te PDF?

He rite tonu te rere - maturuturu, tuhi, tuu, penapena. Ko te "Waitohu" me te "taapiri hainatanga" ka puta he hua ano i roto i ta maatau taputapu.

He herenga ture enei hainatanga?

Āe i te nuinga o ngā rohe ture. Ka tutuki ō mātou putanga huna matua ki ngā paearu EU eIDAS "Advanced Electronic Signature" me ngā whakaritenga US ESIGN / UETA. Mō ngā tuhinga notarisées rānei ngā mahi motuhake QES ka hiahia ana koe ki tētahi tiwhikete nā TSP e kore mātou e taea te hanga i roto i te tūāo — whakamahia Adobe Sign rānei TSP ā-motu.

Kua tukuna taku PDF?

Kao. Ka mahia katoa te hainatanga ki to kaitirotiro. Ko to PDF, hainatanga, me to taviri tūmataiti kaua e pa ki o maatau tūmau.

He aha te rereketanga o nga waitohu hiko me nga waitohu matihiko?

Hiko = tetahi tohu e kitea ana (te tuhi, te ingoa pato, te ahua). Mamati = mahi tuhi e whakaatu ana i te tuakiri + te pono. Ka mahia e matou nga mea e rua, kua tapae ki runga i te hainatanga kotahi. Ko te nuinga o nga kaiwhakataetae kore utu he mahi hiko anake.

He aha te PKCS#7?

Ko te whakawaehere paerewa mo nga raraunga kua hainatia ki PDFs. Ko ia kaitirotiro PDF hou e panui taketake ana i te PKCS#7 / CMS. Ko ta maatau whakaputanga he rite tonu - he rite te whakatakotoranga Adobe Acrobat Pro e whakamahia ana.

Ka mahi te PDF kua hainatia ki te Adobe?

Ae. Adobe Acrobat Kaipānui / Pro, Chrome, Edge, Firefox, Foxit, macOS Arokite - ka whakamanahia o maatau waitohu. Ko nga tohu haina-whaiaro e whakaatu ana i te whakatupato "kaitohutohu" (he tika te whanonga); tukuatu he .p12 mai i te CA whakawhirinaki mo te manatoko tohu-matomato.

Ka taea e au te tuku i taku tiwhikete o naianei?

Ae. I roto i te Certify modal pick "Whakamahia tiwhikete tīariari" ka tukuatu koutou .p12 ranei .pfx kōnae (me te kupuhipa mena kei). Ko te tiwhikete kua paopaohia ki te rohe - kaore i tukuna.

Ka taea e nga tangata maha te haina i te PDF kotahi?

Ae, raupapa. Waitohu me te tango. Ka whakatuwherahia e te kaiwhiwhi ki konei ka haina ano. Ko ia waitohu ka kapi i nga mea o mua - he mekameka manatoko.

Ka taea e au te haina i te PDF i runga i taku waea?

Ae. Mahi i runga i iPhone Safari, iPad (ina koa me Apple Pencil - he rite ki te DocuSign Mobile), Android Chrome. Tuhia ma to maihao.

Ka taea e au te haina i tetahi PDF kua parea-kupuhipa?

Āe mēnā kua rakaina e te kaipupuri, kāo mēnā kua rakaina e te kaiwhakamahi. Mēnā kua rakaina e te kaipupuri, ka mahi tika te hainatanga. Mēnā kua rakaina e te kaiwhakamahi (ka hiahia kupuhipa ki te tuwhera), wetewete mā /unlock-pdf. Ka ahu ā-rohe ngā tūkai e rua.

Kei te mahi tuimotu?

Ae, kua utaina e te ētita. Ka haere te miihini hainatanga ki to kaitirotiro.

Me pehea nga hainatanga wa (RFC 3161)?

Kaore ano kia tautokona - me waea atu nga tohu wa ki tetahi TSA o waho ka takahi i ta maatau oati-a-rohe anake. Mo nga rerengamahi whakamana mo te wa roa (LTV), whakamahia Adobe Acrobat Pro, he ratonga haina arumoni ranei.

Ka kite tetahi kaitirotiro i taku tiwhikete kua hainatia e au he mana?

Kāo — ka kite rātou i te ārai "signer unknown" nō te mea kāore ngā tiwhikete hainatia ake e hono ana ki te raupapa CA pūtake pono. Ko te hainatanga ake KO HAUMARU ā-huna — ko te kerēme tuakiri te mea e hiahia ana ki te whakaaro tūāhu. Mō te whakamahi whaiaro he nui rawa; mō te whakamahi ture/tauwhiti, tukua he .p12 mai i tētahi CA pono.

Ka taea e te kaiwhiwhi te whakatika i te PDF kua hainatia?

Kāo — mēnā ka whakatika rātou, ka pakaru te hainatanga huna matua, ā ka kite tētahi kaitautuhi "signature invalid, document modified after signing". Ko tēnei tōtika te āhuatanga kite-tūkino e tino whakaahuahia ai ngā hainatanga ōpaki i roto i te ture.

Ka whai tohuwai taku waitohu?

Kao. Kei roto i to PDF kua hainatia to hainatanga — karekau he pane kuini "Kua hainatia me te Taputapu Koreutu", kaore he panui, kaore he hokonga ake. Ko taau e haina ana ko nga mea ka tukuna.

He tepe-rahi kōnae?

Kaore he rohe hangai. Ko te maharatanga taputapu anake te tuanui.

Koinei te tino waitohu PDF kore utu?

Āe — mō ngā mahi e kōrero ana mō te tūmataiti me te tango hainatanga huna matua ki te reanga kore utu, ko ō mātou whakaaro pēnei. Mō te whakahaere mahi maha-rōpū (tukua ki ngā kaiini 5, aroturuki āhuatanga), ko DocuSign rānei Adobe Sign te tūkai tika — kāweka kē.

About this tool: PDF Edit is built by a small independent team who were tired of PDF tools that required accounts, uploaded files to servers we didn't control, and gated cryptographic signing behind subscriptions. Everything here runs in your browser — your PDF, your signature drawing, and your private key stay on your device. The signing engine uses the Web Crypto API for RSA key generation and hashing, and produces PKCS#7 / CMS signatures that validate in every modern PDF viewer. Free forever, ad-supported.
