Is this PDF unlocker free?

Yes. 100% free forever — no trial, no premium tier, no per-file charge, no daily quota. Unlock as many PDFs as you want, as often as you want. Ad-supported so it stays free for everyone.

Do I need an account to unlock a PDF?

No. No signup, no login, no email, no captcha, no credit card. Open the page, drop your PDF, enter the password if needed, download the unlocked file.

Is my PDF uploaded to a server?

No. The entire decryption happens locally in your browser. Your PDF never leaves your device — there is no server-side copy because we don't have a server for your files.

Is my password sent to a server?

No. Your password is entered into an input field in this browser tab and used only for local decryption via the Web Crypto API. It is never transmitted anywhere, never logged, never stored. When you close this tab it's gone.

How do I remove password protection from a PDF?

Drop the locked PDF on this page. If it only has an owner password (permission restrictions — printing, copying, editing blocked, but the file opens without a password), we detect that automatically and strip the restrictions with one click. If it has an open password (requires a password to view), enter it in the prompt and click Unlock. The output is a plain unprotected PDF.

What is the difference between an owner password and a user password?

A user password (also called open password) must be entered to view the PDF — without it, the file can't be opened at all. An owner password only restricts what you can do with an already-open PDF: print, copy text, edit, annotate, and so on. Many PDFs distributed from corporate systems are owner-locked but not user-locked — you can open them but can't print or copy. Our unlocker handles both, and auto-detects owner-only locks so you don't have to guess which password to enter.

Can you unlock a PDF without the password?

Yes, but only if the PDF is owner-only locked (restrictions applied but no password required to open). In that case we strip the /Encrypt dictionary using the blank user password that owner-only PDFs implicitly have. If the PDF genuinely requires a password to open (user-locked), no legitimate tool on the web can unlock it without that password — we can't either. Tools that claim to "crack" an unknown password are either scams, extremely slow brute-forcers, or operating on PDFs that are merely owner-locked and don't actually need a password in the first place.

Will the unlocked PDF have a watermark?

No. Your unlocked PDF contains exactly the pages and content from the original document with nothing added. No watermark, no inserted logo, no 'unlocked with…' text, no ad page at the end. The only difference versus the input is that the /Encrypt dictionary is gone.

What encryption formats are supported?

AES-256 R6 V5 (PDF 2.0 / ISO 32000-2 — the modern standard used by Adobe Acrobat, Microsoft Print to PDF, and most corporate systems today) and RC4-128 R3 V2 (legacy, used by older tools). If your PDF uses AES-128 R4 V4 (an uncommon middle-aged variant) we'll surface a clear error — the workaround is to open the PDF in your native viewer with the password, then re-save via Print-to-PDF to produce an unencrypted copy.

Is there a file size or PDF size limit?

No artificial limit. The only ceiling is your device's memory. A modern laptop handles multi-hundred-MB PDFs without trouble. Mobile browsers comfortably handle documents up to ~200 pages; older phones may run short on memory above 1000 pages.

Can I unlock a PDF on my phone?

Yes — open this page in your phone's browser, tap Select PDF, choose the file, enter the password if prompted, and tap Unlock. Works on iPhone Safari, iPad, Android Chrome, and every other modern mobile browser. No app install required.

Does it remove print, copy, and edit restrictions?

Yes. Those restrictions are stored in the PDF's /Encrypt dictionary. When we strip the encryption, the restrictions go with it. The output PDF allows all operations your viewer supports — printing, text copy, commenting, editing, extraction for accessibility, page assembly. Think of it as producing a brand-new PDF from the same visible content.

Is unlocking a protected PDF legal?

Unlocking a PDF you own, or one you have permission to modify, is legal and is the entire reason this tool exists. Common legitimate use cases: you password-protected your own document and forgot the lock, IT sent you a print-restricted PDF you need to annotate for a meeting, you received a signed contract and need to reprint it with corrected formatting. Respecting the original owner's intent is on you — we don't judge the use case, but we also can't help you bypass protections on content you don't own the rights to distribute.

Does it work offline?

Yes, once the page has loaded. The unlocker runs entirely in your browser — you can disconnect from the internet and keep working. Great for sensitive PDFs (medical, legal, financial) you'd rather process without a network connection active.

What's the difference between unlocking and decrypting a PDF?

They're the same operation with different names. 'Decrypt' emphasizes the crypto-technical side — running AES or RC4 in reverse over the encrypted object streams. 'Unlock' emphasizes the user-facing outcome — a PDF that no longer needs a password. This tool does both at once: it decrypts every object stream AND removes the /Encrypt dictionary, leaving a plain unprotected PDF.

Is this the best PDF unlocker?

For privacy-first workflows where you don't want your password or your PDF to touch anyone else's server, we think so — and we explicitly compare ourselves to iLovePDF, Smallpdf, Adobe, Syncfusion, and PDF2Go below. For a cloud-synced workflow with history across devices, Adobe Acrobat online may fit better. Pick the tradeoffs that match your actual needs.

Wewete PDF — Tango Kupuhipa, Tere me te Motuhake

Wewetehia te whakamarumaru kupuhipa mai i te PDF — i te rohe, i to kaitirotiro, kaore he tukunga ake

Drop a password-protected PDF and we remove the lock. Owner-only restrictions (print / copy / edit disabled) are detected automatically and removed without asking you for anything. Open-password PDFs unlock when you type the password — the password stays on your device, never sent anywhere. 100% in-browser. No upload, no signup, no watermark, no file limit.

Me pehea te Wewete i te PDF me te Tango i te Parenga Kupuhipa

1. Whakatakahia to PDF kua parea-kupuhipa

Toia te PDF kua raka ki runga i te rohe taka i runga, ka paato ranei ki te tirotiro. Ka utaina te konae ki roto i to kaitirotiro — kaore he mea ka tukuna ki te tūmau.

2. Rapu-aunoa te rangatira vs raka kaiwhakamahi

Ka tirotirohia e matou te papakupu whakamunatanga a PDF. Mena kua maukati-anake-anake (nga whakaaetanga engari karekau he kupuhipa hei whakatuwhera), ka wetekina tonu - karekau he wawe. Ki te hiahia he kupuhipa hei whakatuwhera, ka whakaatu matou ki a koe te mara kupuhipa.

3. Patohia te kupuhipa (mehemea e hiahiatia ana)

Whakauruhia te kupuhipa tuwhera OR te kupuhipa rangatira - ka whakaaehia e te PDF spec tetahi. Ka whakamahia to kupuhipa i te rohe e te Web Crypto API kei roto i to kaitirotiro. Kore rawa e tukuna, kua takiuru, kua rongoatia ranei.

4. Tikiake i te PDF kua wetekina

Pāwhiritia Wewete PDF. Ko te konae wetemuna ka mahia i te rohe me te papakupu /Whakamuna kua tangohia. Ka whakatuwherahia i roto i tetahi kaitirotiro PDF me te kore tono mo te kupuhipa - ka tangohia katoatia nga taapiri, te kape, te whakatika, me te tuhi korero.

He aha tenei te tino pai rawa atu mo te Wewete PDF

100% tukatuka rohe

Ka noho to PDF ME to kupuhipa ki to taputapu. Whakatauritea: iLovePDF, Smallpdf, Adobe, Tukutahi, me PDF2Go ka tukuna katoatia nga mea e rua. Ina wetewete ana koe i te PDF, he raru tūmataiti rua tena — ka mau poto i a raatau te konae me te ki. Kare matou: kaore e taea e matou te kite na te mea karekau he tūmau mo o konae.

Kaipupuri-anake te kimi-aunoa

Ko te nuinga o nga PDFs kua parea ki a koe (nga punaha rangatōpū, puka a te kawanatanga, tuhinga kua herea-taapiri) kua maukatihia e te rangatira, ehara i te mea maukati-kaiwhakamahi — ka tuwhera kaore he kupuhipa engari ka aukati i te ta me te kape. Ka kitea e matou tera ka iriti me te kore whakauru. Ka akiakihia koe e nga kaiwhakataetae ki te pato i tetahi mea ahakoa kaore he kupuhipa e hiahiatia ana.

AES-256 me RC4 e rua i tautoko

Ko te paerewa hou (AES-256 R6 V5, e whakamahia ana e Adobe Acrobat, Microsoft Office, me nga kaihanga PDF tata nei) ka mahi. Ko te mea tuku iho (RC4-128 R3 V2) e mahi ana mo nga tuhinga tawhito. Mena kei te whakamahi to PDF i tetahi momo rerekee AES-128 R4 V4 waenga-pakeke ka puta ake he huarahi mahi maamaa engari kaua e ngaro.

Karekau he rahinga konae, he rohe tatau wharangi ranei

Whakatakahia he 5-wharangi PDF, he pukapuka pukapuka 500-wharangi, he putea ture maha-rau-MB ranei. Ka herea anake e te mahara taputapu. iLovePDF me te Smallpdf cap te whakamahi kore utu i etahi mahi mo ia haora me te rahi o nga konae kei te 25–200 MB. Kaore matou.

Tino Whakakore, mo ake tonu atu

Kaore he whakamatautau, kaore he taumata utu, kaore he utu mo ia kōnae. Wewetehia te maha o nga PDF e hiahia ana koe, i nga wa e hiahia ana koe. Ka tautokohia te panui kia noho kore utu mo te katoa.

Kaore he kaute, kaore he imeera

Me timata tonu te wetewete. Kaore he hainatanga, kaore he hopu imeera, kaore he kaari nama. Ko te mahi a te rorohiko papamahi i mua i nga "whakamatautau kore utu" ka noho hei mahanga.

Ka mahi tuimotu

Kia utaina tenei wharangi ka taea e koe te momotu mai i te ipurangi ka mahi tonu te kaiwhera. He pai mo nga PDFs tairongo (te rongoa, te ture, te putea) ka pai ake koe ki te tukatuka me te kore he hononga whatunga.

Kaore he tohuwai i runga i te putanga

Kei roto i te PDF kua wetekina nga ihirangi o to whakaurunga. Karekau he tohu taapiri, karekau he hiku, karekau he raina "kua wetekina ki te ...", kaore he whaarangi panui i te mutunga. Putanga ma, i nga wa katoa.

He rite te waehere ki te ētita

Ko te tikanga wetemunatanga he ara waehere rite tonu te whakamahi a te etita PDF Edit matua hei whakatuwhera i nga tuhinga whakamunatia. Kotahi te whakatinanatanga, kua whakamatauria te whawhai ki nga mano o nga PDFs o te ao. Ka whakamahia ano e matou ki konei, kaua ki te tuku i te kape tuarua, he iti ake te whakamatautau.

Nga Momo Kupuhipa e rua PDF, Kua whakamaramatia

Kupuhipa Kaiwhakamahi (kupuhipa tuwhera)

Koinei te mea e kiia ana e te nuinga o te tangata ko "PDF kupuhipa". Kua tutakina te konae - ka akiakihia koe e to kaitirotiro i mua i to kite i nga ihirangi. Ko nga puna tikanga: nga peeke e whakamuna ana i nga korero, nga kaituku mahi e tuku pepa utu, nga roia e whakawhiti ana i nga konae keehi. Hei iriti i tetahi o enei i konei, me mohio koe ki te kupuhipa. Ka patohia e koe, ka wetewetehia e matou nga awa ihirangi i te rohe, ka tangohia te papakupu /Whakamuna, ka whakaputa i te PDF.

Kupuhipa rangatira (kupuhipa whakaaetanga)

He ngawari ake tenei. Ka puare noa te konae — karekau he kupu whakahau — engari ka aukatia etahi mahi: te ta, te kape tuhinga, te whakatika, te tuhi, te tango wharangi. He maha nga punaha umanga e whakaputa ana i nga PDFs kua tutakina e te rangatira ma te taunoa (whakaaro "kaua e ta me te kore whakamana" whakatupato). Ka taea e koe te iriti i konei me te whakaurunga ZERO: whakataka te konae ka kitea kua putua te kupuhipa kaiwhakamahi, tangohia nga here, kua oti. Ko te nuinga o nga kaiwhakataetae ka tono tonu ki a koe ki te pato i tetahi mea, ahakoa kaore he mea e hiahiatia ana.

Ko nga konae me nga raka e rua

Ka taea e te PDF he kupuhipa tuwhera me tetahi kupuhipa rangatira motuhake mo nga whakaaetanga. Ko te PDF spec e kii ana ka taea e tetahi te whakatuwhera i te konae. Ka tukuna koe ki te whakauru i nga mea e mohio ana koe - ka whakamatauhia e to maatau kaiwhakamaori te ara kupuhipa-kaiwhakamahi i te tuatahi, ka hoki ki te ara rangatira-kupuhipa. Kotahi te mara, e rua nga keehi i whakahaerea.

Ko nga konae kaore e tino mohiotia te kupuhipa

Mena he PDF kua maukati-kaiwhakamahi me te kore koe e mohio ki te kupuhipa, kaore he taputapu mana e taea te iriti. He tino kaha te whakamunatanga (AES-256, RC4 ranei he ngoikore ake engari me whai matua tonu). Ko nga taputapu e kii ana ki te "whakaora" i tetahi kupuhipa e kore e mohiotia ko (a) he kupu huna noa, he maha nga ra e mahi ana mo nga kupuhipa ngoikore, (b) mahi tinihanga ranei. Mena kua ngaro koe i a koe ake kupu huna, ko te whakautu pono ko te tono kape hou mai i te tangata nana i tuku — ka whakahaere ranei i te whakaeke papakupu me tetahi taputapu motuhake i runga i to ake miihini.

The point isn't that iLovePDF or Adobe are bad tools — they're not. The point is that if you care about not uploading your PDF and your password in the same request to someone else's server, you need a local-only unlocker. We built one. Nobody else in the top ten has.

Ko wai te Wewete PDFs?

Te tango i nga here taarua me te kape

Ko nga tauira rangatōpū, puka a te kawanatanga, me nga rauemi matauranga ka tohatohahia me te kape / kape kua aukatihia "mo te haumarutanga" — ahakoa karekau te ihirangi i te tairongo. Mena ka hiahia koe ki te ta i tetahi puka kua riro ia koe, ka kape ranei i tetahi korero mai i te PDF e mau tika ana koe, iriti ka kore nga here.

Tou ake kupuhipa, kua warewaretia

I tiakina e koe he PDF i te tau kua hipa, kaore i tiakina e te kaiwhakahaere kupuhipa, inaianei kaore e taea e koe te whakatuwhera i to ake konae. Mēnā he tūponotanga he rangatira-anake te raka (he mea noa i te wa i taapirihia te whakamarumaru ma te "whakatikatika" kaua ki te "whakamuna me te kupuhipa"), tohua ki konei - ka wetewete ma te kore whakauru. Mena he raka-kaiwhakamahi pono, ka hiahia koe ki te kupuhipa.

Te haina ano i tetahi kirimana kua hainatia

Ka tae mai te kirimana kua maukatihia e te punaha rerengamahi a te kaituku. Ka whakatuwherahia e koe, ka hainatia, katahi ka mohio ka kore to kaitirotiro PDF e tuku kia penapena koe na te raka. Wewete i te tuatahi, haina-a-te-rua, tukuna ano.

Te tuhi i tetahi tuhinga tohutoro

Ko nga pepa rangahau, nga pukapuka-e, me nga tohutoro PDFs ka tohatohahia i etahi wa ka aukatihia nga korero. Wewete ki te taapiri i o tuhipoka ako, miramira, korero tawhē ranei i te rohe - kare rawa o tuhipoka e hoki ki te puna taketake.

Te hanumi me etahi atu PDFs

Ko te nuinga o nga taputapu hanumi PDF kaore e whakaae ki te whakauru i tetahi konae kua maukati-kupuhipa, ahakoa ka mohio koe ki te kupuhipa. Wewete kotahi, hanumi me te kore waku. He pai te mahi hei takahanga i mua i to maatau taputapu /hanumi-pdf.

Puranga mo te wa roa

Ko te tuhinga kua parea-kupuhipa e aro nui ana koe (whakahoki taake, rekoata rongoa) tetahi kupuhipa kua warewarehia kia kore e taea te whakaora. Mo nga purongo whaiaro e whakahaerea ana e koe, iriti tuatahi ka penapena i te putanga maamaa ki roto i to ake taapiri whakamunatia, kaua ki te whakawhirinaki ki te kaupapa whakauru a PDF.

Te urunga o te kaipānui mata

Ko te PDF "tango mo te urunga" whakaaetanga ka whakahaere mena ka taea e nga kaipanui mata te uru ki nga ihirangi tuhinga. He maha nga wa e aukatihia ana e te rangatira-raka PDFs. Ka whakakorehia e te Wewete te here — ka uru te tuhinga ki te hangarau awhina.

Te tā ki te hōputu rahi ake

Ko etahi PDFs kua maukati ki te tuku i te taa-taumira iti anake. Ko te wetewete ka tango i te here, na reira ka taea e koe te tuku ki te kaitoi, ki te kaituhi whakaahua ranei ma te pono.

Te whakatuwhera i nga tuhinga whakamuna tuku iho

Ko nga PDFs tawhito RC4-whakamunatia mai i te timatanga o te 2000s i etahi wa ka kore e tuwhera ma te maataki i nga kaimakitaki hou. Wewetehia te whakamunatanga tuku iho me te whakaputa i te PDF maataki ka taea e tetahi kaitirotiro hou te whakahaere me te kore e ngangau.

Wewete PDF i runga i te iPhone, Android, Mac, Windows, me te Chromebook

Kei te mahi to maatau iriti PDF i runga i nga taputapu katoa me te tirotiro hou - Windows, Mac, Linux, Chromebook, iPad, iPhone, me Android. 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 wetewete tonu - ka rere nga mea katoa i te rohe ma te API Crypto Tukutuku a to kaitirotiro. Ka whakamahia e te whakauru kupuhipa he mara kupuhipa paerewa, na ka taea e te kaiwhakahaere kupuhipa o to taputapu te whakakii aunoa mena kei a ia te tohu kua tiakina.

Me pehea te mahi a te PDF i runga i te kaitirotiro i te maukati?

Kua panuitia to PDF ki roto i te mahara o to kaitirotiro. Mena kei a ia he papakupu /Whakamuna, ka wetewete matou i nga tawhā whakamunatanga (putanga taurangi, whakahounga, raraunga hianga kaiwhakamahi/rangatira). Mo te AES-256 R6 V5, ka whakahaerehia e matou te mahi whakamana-kupuhipa PDF 2.0 ma te whakamahi SHA-256/384/512 me te AES-128-CBC te ranu hei tiki mai i te kii konae mai i to kupuhipa, katahi ka whakamahi i taua ki ki te AES-256-CBC te wetewete i nga awa ahanoa whakamunatia. Mo te RC4 R3 V2, ka whakahaerehia e matou te MD5 te takenga matua me te RC4 awa-whakaweto i runga i ia ahanoa. Kia noho noa nga awa katoa, ka hanga ano e matou te PDF kaore he papakupu /Whakamuna. Ko te putanga he PDF 1.7 paerewa e tuwhera ana ki ia kaitirotiro hou. Ka rere nga crypto katoa i roto i to kaitirotiro ma te API Tukutuku Crypto - kaore he tūmau i uru ki tetahi taahiraa, kaore hoki to kupuhipa e tukuna.

Pātai Auau

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

Whakatakahia to PDF kua raka ki te wharangi o runga. Mena he rangatira-anake-maukati, ka iriti aunoa matou. Mena he kupuhipa tuwhera, whakauruhia te kupuhipa (ka noho ki to taputapu) ka paato i te Wewete PDF.

Me pehea taku tango kupuhipa mai i te PDF?

He rite ano ki te iriti — ka tangohia katoatia e ta maatau taputapu te /Whakamuna papakupu. Ko te hua o te PDF ka tuwhera me te kore he tohu kupuhipa, karekau he herenga ta/kape/whakatika.

Kua tukuna taku PDF ki hea?

Kao. Ka haere te wetemunatanga i roto i to kaitirotiro. Ko to PDF kaore e pa ki o maatau tūmau na te mea karekau he tūmau mo o kōnae.

Ka tukuna taku kupuhipa ki te tūmau?

Kao. Ka whakamahia te kupuhipa i te rohe e te Web Crypto API. Kore rawa e tukuna, kua takiuru, kua rongoatia ranei. Katia te ripa ka kore.

Ka taea e au te iriti i te PDF kaore he kupuhipa?

Ae, mena ka maukati te PDF ki te rangatira-anake (he aukati nga whakaaetanga engari kaore he kupuhipa hei whakatuwhera). Ka kitea aunoa e matou aua mea. Mo PDFs kua maukati-kaiwhakamahi, karekau he taputapu tika e taea te iriti me te kore te kupuhipa.

He aha nga tikanga whakamunatanga e tautokohia ana?

AES-256 R6 V5 (te paerewa hou) me RC4-128 R3 V2 (tuku iho). Mena kei te whakamahi to PDF i te AES-128 R4 V4 ka whakaatuhia e matou he karere hapa marama me te whakaaro he whakatika.

Ka whai tohuwai te putanga?

Kao. Ko to PDF kua wetekina ko to urunga me te whakamunatanga kua tihorea - kaore he mea taapiri.

He tepe-rahi kōnae?

Kaore he rohe hangai. Ko te maumahara o to taputapu anake te tuanui.

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

Ae. Ka mahi i runga i te iPhone Safari, iPad, Android Chrome, me era atu tirotiro pūkoro hou. Karekau he tono whakauru e hiahiatia ana.

Kei te mahi tuimotu?

Ae, kua utaina te wharangi. Ka haere katoa te wetewete i to kaitirotiro.

He aha te rereketanga o te kupuhipa rangatira me te kupuhipa kaiwhakamahi?

Paraka kupuhipa kaiwhakamahi e whakatuwhera ana i te konae. Ko te kupu huna a te rangatira ka taea te whakatuwhera engari ka aukati i nga mahi tuhi / kape / whakatika / tangohanga. Ka whakaaehia e te PDF spec tetahi mo te iriti katoa - ka whakamatau ta maatau kaiwhakamahara ki te kaiwhakamahi-tuatahi, rangatira-tuarua.

Kei te ture te iriti i te PDF?

Āe mēnā nā koe te PDF rānei he uru kua tukua ki a koe ki te whakarereke. Kāo mēnā e karo ana koe i te ārai mō ngā ihirangi kāore ōu tika. Kāore mātou e whakawā ana ki te āhua o te whakamahi engari e kore hoki e āhei mātou ki te āwhina i a koe ki te takahi tika auteur.

Ka taea e au te iriti i te PDF ka here noa (kaore i te whakamunatia-kupuhipa)?

Ae — koinei te take rangatira-anake. Ka kitea aunoatia e matou, ka murua nga here me te kore tono mo tetahi mea.

Ka tiakina e te kai iriti nga mara puka me nga waitohu?

Āe mō ngā āpure tukwhanau, kāo mō ngā hainatanga ōpaki. Ka tiakina ngā āpure tukwhanau. Ka taea pea te whakakore i ngā hainatanga ōpaki nō te mea ka hono te hainatanga ki te au byte tūturu o te PDF whakamuhu o mua — ka huri ērā bytes te wetewete. Mēnā e whirinaki ana ō mahi mō te tūturu o te hainatanga, kaua e wetewete i te kōnae; huakina rānei i roto i tētahi kaitiro e tautoko ana ki te pānui tuhinga hainatia-whakamuhu.

Ka taea e au te tiaki ano i te PDF kua wetekina i muri mai?

Ae. Ko te waahanga Tiaki a to maatau etita matua e pa ana ki te whakamunatanga AES-256 hou me to kupuhipa kua tohua. Ko te haerenga-a tawhio noa (wewete → whakatika → tiaki ano) he rerenga mahi noa.

Koinei te tino pai o te iriti PDF?

Āe — mō ngā mahi e kōrero ana mō te tūmataiti e kore ai e tūpono te PDF me te kupuhipa ki tētahi tūmau, ko ō mātou whakaaro pēnei. Mō ngā mahi tūhonohono ki te kapua i ngā pūrere, he pai ake pea a Adobe Acrobat online. Kōwhiria ngā whakaaro e taunoa ana.

About this tool: PDF Edit is built by a small independent team who were tired of PDF tools that required accounts, watermarked outputs, and uploaded files (and passwords!) to servers we didn't control. Everything here runs in your browser — your PDF and your password stay on your device, there's no file limit, no signup, and no watermark on the output. The decryption code reuses the exact same implementation our main editor uses to open encrypted documents, so it's battle-tested on real-world PDFs. Free forever, ad-supported. Reach out via the footer links with bugs or feature requests — we read every message.

Kua reri to PDF kua wetekina!

✏️ Whakatika Kuputuhi 📎 Whakakotahi ✂️ Wehewehe 📦 Kōpeke

I don't like greed — or that we've lost privacy and ownership over our own tools. So I'm building software to combat this. No hidden accounts, no data mining, no paywalls. Just software that does what it has to.

Your password never left this tab. Karekau noa.

100% mahi ā-rohe

Ka tukuna e te katoa o nga kaiwhera PDF ipurangi to konae ME to kupuhipa ki o raatau tūmau, ka wetewetehia ki reira, ka hoatu he hononga tikiake ki a koe. Ka rere katoa matou ki roto i tenei ripa tirotiro - ko te PDF me te kupuhipa ka noho ki te mahara taputapu i te wa katoa. Karekau he kape taha tūmau na te mea karekau he tūmau mo o kōnae.

Kāore he whakamātautau, kāore he mahi tinihanga, kāore he mahanga
