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.

Saxeex PDF - Bilaash, Gaar ah, Farshaxan

Saxiixa muuqda iyo saxeexyada dhijitaalka ah ee cryptographic dhabta ah (PKCS#7) - labadaba bilaash, labadaba maxalli ah, labadaba si sharci ah loo aqoonsan yahay

Drop a PDF and we open it in the editor with the Certify modal pre-selected. Draw your signature with mouse / trackpad / finger, type your name, or upload a signature image. Add reason / location / date fields. Place the visible signature anywhere on the page. We cryptographically sign the output using an in-browser-generated RSA-2048 self-signed certificate (or your own .p12 if you have one). Your PDF, your signature, and your private key never leave your device. No signup, no watermark, no per-signature charge. The only free PDF signer that does real cryptography.

Saxiixa Elektaroonigga ah vs. Saxiixa Dijital ah - Maxaa Dhab ahaantii haya

Saxeexa elegtarooniga ah (SES - Fudud)

Calaamad kasta oo ka muuqata dukumeentiga dhijitaalka ah: magac la qoray, far la sawiray, saxeex qalin-qoyan oo la sawiray, sanduuqa hubinta "Waan oggolahay". Si sharci ah ayaa looga aqoonsan yahay inta badan awoodaha ganacsi maalmeedka (EU eIDAS SES tier, US ESIGN / UETA, UK ESIGN / UETA, UK Xeerka Isgaarsiinta Elektrooniga ah) laakiin way sahlan tahay in lagu tartamo haddii saxiixuhu uu mar dambe diido saxiixa - ma jirto caddayn qarsoodi ah oo soo saartay calaamadda. Habkayaga "kaliya muuqda" ayaa soo saaraya tan.

Saxeexa sare ee elektiroonigga ah (AES)

EU eIDAS xeerbeegtida heerka 2. Waa in (a) si gaar ah u aqoonsada saxiixaha, (b) in ay hoos yimaadaan kantaroolka kaliya ee saxeexaha, (c) in la ogaado faragelinta saxeexa kadib, (d) in la sameeyo iyada oo la isticmaalayo xogta uu saxeexuhu ku ilaalin karo iyaga oo keliya. Wax soo saarkeena sirta ah (PKCS#7 ee ka sarreeya SHA-256 oo wata RSA-2048 iyo fure gaar ah oo laga soo saaray gudaha gudaha kaydinta Web Crypto ee aan la soo saari karin) ayaa buuxiya dhammaan afarta shuruudood - waxaad codsan kartaa heerka AES ee PDF halkan lagu saxiixay.

EU eIDAS heerka 3. AES iyo shahaado u qalma oo ka socota Bixiyaha Adeegga Aaminaada (TSP) ee ku jira liiska EU-da ee la aamini karo, oo lagu daray aaladda saxeexa u qalma (HSM ama smartcard). QES waxay sharci ahaan u dhigantaa saxiixa qalin-qoyan ee EU oo dhan. Ma soo saarno QES sababtoo ah qulqulka browser-kaliya ma buuxin karo shuruudaha qalabka saxeexa ku salaysan - waxaad u baahan tahay qalab saxeex oo go'an ama HSM daruur ah. Haddii kiiskaaga isticmaalku si gaar ah ugu baahan yahay QES (qandaraasyada nootaariyada ah, warshadaha la xakameeyey qaarkood), waxaad u baahan tahay Saxeexa Adobe, DocuSign EU Qualified, ama TSP maxalli ah.

Sharciga Mareykanka (ESIGN / UETA)

US federal ESIGN Act (2000) iyo ku korsashada gobolka UETA waxay ula dhaqmaan inta badan saxeexyada elektiroonigga ah si sharci ahaan u dhigma qalin-qoyan - iyada oo aan la hayn nidaamka EU-da. Si saxeexu u noqdo mid la fulin karo: (a) labada dhinacba waa inay ogolaadaan inay si elektaroonik ah u saxeexaan, (b) saxeexu waa inuu ahaadaa mid ula kac ah, (c) diiwaanada waa in la hayaa. Dhammaan kuwan waa kuwo shaqeynaya; Wax-soo-saarkayaga ayaa la kulma iyaga. Qaar ka mid ah noocyada dukumeentiyada gaarka ah ayaa la xardhay (dardaaran, arrimaha sharciga qoyska, dacwadaha maxkamadda qaarkood) - hubi gobolkaaga.

Go'aamada guddiga shirkadda

Daqiiqadaha guddiga, go'aamada oggolaanshaha, deeqaha ikhtiyaarka saamiyada. Taageerada silsiladaha saxeexayaasha badan waxay u ogolaataa agaasimayaasha inay si isdaba joog ah u saxeexaan iyaga oo aan u gudbin PDF iyada oo loo marayo daruur dhinac saddexaad ah.

Kaydinta dukumeentiga muddada-dheer

Saxeex PDF muhiim ah maanta oo leh saxeex cryptographic oo taarikhdu ku shaabadaysan tahay. Ku kaydi gudaha. Sannado ka dib, qof kasta oo haysta faylka ayaa weli xaqiijin kara inuu saxeexay qofka haysta furahaaga gaarka ah oo aan la beddelin tan iyo markaas.

Saxeex PDF iPhone, Android, Mac, Windows, iyo Chromebook

Saxeexeeyahayaga PDF wuxuu ku shaqeeyaa qalab kasta oo leh browser casri ah - Windows, Mac, Linux, Chromebook, iPad, iPhone, iyo Android. On iPad Pro ee leh Apple Pencil, sawirida saxeexaagu waxa uu dareemaya sida abka mobaylka ee DocuSign, laga jaray rukunka oo laga jaray rarida. Ma jiro abka rakiban, majiro plugins, ma jiro xuquuq maamul.

Sidee buu u shaqeeyaa saxeexa Cryptographic-ku salaysan PDF?

Markaad gujiso Save, waxaanu ku soo saareynaa furaha RSA-2048 cusub browserkaaga anagoo adeegsanayna Web Crypto API (crypto.subtle.generateKey) - furaha gaarka ah wuxuu ku nool yahay kaydka aan la soo saari karin lamana dhoofin karo. Waxaan dhisnay X.509 shahaado iskiis u saxeex ah oo leh magaca saxeexaha aad dooratay. PDF waxaa lagu diyaariyay meel madhan/Sig meeleeyaha gudaha aagga /AcroForm. Waxaan xisaabineynaa xashiish SHA-256 ee kala duwanaanshaha byte ee dukumeentiga marka laga reebo meeleeyaha.

Daawade kasta oo PDF casri ah (Adobe, Chrome, Edge, Foxit, Horudhac, Firefox) waxa uu akhriyaa qaab dhismeedka PKCS#7 ee furan, dib u xisaabiya xashiishka dukumeentiga, ka xaqiijiyaa saxeexa ka dhanka ah shahaadada ku dadan, oo muujiya calaamada xaqiijinta. Dhammaan crypto waxay ku shaqeeyaan biraawsarkaaga - majiro server, wax la soo geliyo, telemetry ma jiro.

Su'aalaha Inta Badan La Isweydiiyo

Sideen bilaash ugu saxeexaa PDF?

Ku rid PDF kaaga bogga sare. Tifaftiruhu wuxuu ku furaa habka Shahaadaynta ee horay loo doortay. Sawir, qor, ama soo rar saxiixaaga. Guji bogga si aad u dhigto Guji Save. Bilaash, maxalli ah, malaha calaamad-biyood

Sideen ugu daraa saxeexa PDF?

Socod isku mid ah - tuuri, sawir, meel, badbaadi. "Saxiix" iyo "ku dar saxiix" waxay keenaan natiijo isku mid ah qalabkayaga.

Saxiixahan si sharci ah ma u xidhan yihiin?

Haa inta badan xukunada Wax-soo-saarkayaga sir-garaafigu wuxuu la kulmaa EU eIDAS "Saxiixa Sare ee Elektarooniga ah" shuruudaha wuxuuna qanciyaa shuruudaha US ESIGN / UETA. Dukumeentiyada nootaaysiinta ama qulqulka shaqada ee QES-gaarka ah waxaad u baahan tahay shahaado ay bixisay TSP oo aynaan ka soo saari karin browser-ka isticmaal Adobe Sign ama TSP qaran.

PDF kayga ma la shubay?

Maya. Saxeexdu waxay gabi ahaanba ku dhacdaa browserkaaga. PDF, saxeexaaga, iyo furahaaga gaarka ah waligood ma taaban seerfaradayada.

Waa maxay faraqa u dhexeeya saxeexyada elektaroonigga ah iyo kuwa dhijitaalka ah?

Electronic = calaamad kasta oo muuqata (qoraal, magac teeb ah, sawir). Dijital = hawlgal qarsoodi ah oo caddaynaya aqoonsiga + daacadnimada. Labadeenaba waanu samaynaa, anagoo dul saaran hal warqad saxeex ah. Inta badan tartamayaasha bilaashka ah waxay sameeyaan elektaroonik kaliya.

Waa maxay PKCS#7?

Codaynta caadiga ah ee xogta saxeexan ee PDFs. Daawade kasta oo casriga ah PDF wuxuu u akhriyaa PKCS#7 / CMS asal ahaan. Wax soo saarkayagu waa u hoggaansan yahay gaar ahaan - qaab isku mid ah Adobe Acrobat Pro ayaa isticmaala.

PDF ee saxeexan ma ku shaqayn doonaa Adobe?

Haa Adobe Acrobat Akhristaha / Pro, Chrome, Edge, Firefox, Foxit, macOS Horudhac - dhammaan waxay xaqiijiyaan saxiixyadayada. Shahaadooyinka is-saxiixa ayaa muujinaya digniin "saxiix aan la garanayn" (dhaqan sax ah); ka soo rar .p12 CA ah oo la aamini karo si loo xaqiijiyo calaamada cagaaran.

Ma geli karaa shahaadadayda jirta?

Haa Habka Certify ka soo qaado "Isticmaal shahaado jirta" oo soo rar faylkaaga .p12 ama .pfx (oo wata erayga sirta ah haddii uu jiro). Shahaadada waxaa lagu qiimeeyaa maxali ahaan - waligeed lama gudbiyo.

Dad badan ma saxiixi karaan isla PDF?

Haa, si isku xigta. Saxiix oo soo deji. Qaataha ayaa furay halkan oo mar kale saxeex Saxiix kastaa wuxuu daboolayaa kuwii hore - silsilad la xaqiijin karo.

Ma ku saxiixi karaa PDF taleefankayga?

Haa Waxa uu ka shaqeeyaa iPhone Safari, iPad (gaar ahaan Apple Pencil — waxa uu dareemayaa sida DocuSign Mobile), Android Chrome. Farta ku sawir.

Ma saxiixi karaa PDF sirta lagu ilaaliyo?

Haa haddii mulkiiluhu xidhan yahay, maya haddii isticmaaluhu xidhan yahay. Haddii mulkiiluhu xidhan yahay, saxeexu si toos ah ayuu u shaqeeyaa. Haddii isticmaaluhu xiran yahay (password-ka loo baahan yahay in la furo), fur fur/unlock-pdf marka hore. Labada qalabba waxay ku shaqeeyaan gudaha.

Ma ka shaqeeyaa offline?

Haa, mar tafatiruhu soo shubo Matoorka saxeexa wuxuu ku shaqeeyaa browserkaaga.

Ka warran saxeexyada wakhtiyada la dhejiyay (RFC 3161)?

Weli lama taageero - timestamps waxay u baahan tahay wicitaan shabakad TSA dibadda ah taas oo jebisa ballan-qaadkayaga kaliya ee maxalliga ah. Xaqiijinta muddada fog (LTV) socodka shaqada, isticmaal Adobe Acrobat Pro ama adeegga saxiixa ganacsiga.

Xaqiijiye ma u arki doonaa shahaadadayda aan saxiixday inay sax tahay?

Maya - waxay arki doonaan digniin "saxiix aan la garanayn" sababtoo ah shahaadooyinka is-saxiixa ah kuma xirna xidid la aamini karo ee silsiladda CA. Saxiixa laftiisa ayaa si qarsoodi ah u shaqeynaya - waa sheegashada aqoonsiga ee u baahan kalsoonida dhinac saddexaad. Isticmaalka shakhsi ahaaneed waa ku filan; isticmaalka sharci/ganacsi, ka soo rar .p12 CA la aaminsan yahay.

qaataha wax ma tafatiri karaa PDF saxiixa?

Maya — haddii ay wax ka beddelaan, saxeexa cryptographic wuu jabaa oo xaqiijiye kastaa wuxuu arkaa "saxiixa mid aan sax ahayn, dukumeenti la beddelay ka dib saxiixa". Tani waa sida saxda ah hantida lagu ogaanayo faragelinta ee ka dhigaysa saxiixyada dhijitaalka ah sharci ahaan macno.

Saxeexaygu ma yeelan doonaa calaamad biyood?

maya Waxa aad saxeexdo waa waxa la soo diro.

Ma jiraa xadka cabbirka faylka?

Ma jiro xad macmal ah. Xusuusta aaladda ayaa ah saqafka keliya.

Kani ma saxeexaha PDF ee ugu fiican ee bilaashka ah?

Haa - socodka shaqada ee ugu horeysa ee gaarka ah iyo helitaanka saxeexyada cryptographic ee heerka bilaashka ah, waxaan u maleyneynaa sidaas. Qabanqaabinta socodka shaqada ee xisbiyada badan (u dir 5 saxiixayaasha, heerka raadraaca), DocuSign ama Adobe Sign waa aaladda saxda ah - qayb ka duwan.

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.
