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.

Akukho watermark kwimveliso

I-PDF evuliweyo iqulethe kanye umxholo wegalelo lakho. Akukho logo yongeziweyo, akukho mbhalo wasezantsi, akukho "ukuvulwa nge..." umgca, akukho phepha lentengiso ekugqibeleni. Imveliso ecocekileyo, rhoqo.

Ikhowudi efanayo njengomhleli

Indlela yokususa uguqulelo oluntsonkothileyo ikwayindlela enye yekhowudi esetyenziswa ngumhleli omkhulu we-PDF Edit ukuvula amaxwebhu afihliweyo. Uphumezo olunye, luvavanyiwe kwidabi kumawaka ee-PDFs zehlabathi lokwenyani. Siphinda siyisebenzisa apha kunokuthumela ikopi yesibini, evavanywa kancinci.

Iindidi ezimbini ze-PDF Password, ezicacisiweyo

Igama lokugqitha lomsebenzisi (vula igama lokugqitha)

Le yeyona nto ithethwa ngabantu abaninzi ngokuthi "PDF password". Ifayile itshixiwe ivaliwe - umbukeli wakho uyakukhokelela phambi kokuba ubone nawuphi na umxholo. Imithombo yolwazi eqhelekileyo: iibhanki eziguqulela ingxelo entsonkothileyo, abaqeshi bathumela amaphetshana emivuzo, amagqwetha atshintshiselana ngeefayile zetyala. Ukuvula enye yezi apha, kufuneka wazi igama eligqithisiweyo. Nje ukuba uyichwetheze, sisusa uguqulelo lokuntsonkotha komxholo ekuhlaleni, sihlube isichazi-magama / Fihla, kwaye sikhuphe i-PDF ecacileyo.

Igama lokugqitha lomnini (igama lokugqitha lemvume)

Le yona inobuqili. Ifayile ivula ngokuqhelekileyo - akukho myalelo wephasiwedi - kodwa imisebenzi ethile ivaliwe: ushicilelo, ikopi yokubhaliweyo, ukuhlela, isichasiselo, ukutsalwa kwephepha. Iisistim ezininzi zeshishini zivelisa umnini-PDFs otshixiweyo ngokungagqibekanga (cinga "ungashicileli ngaphandle kogunyaziso" izilumkiso). Ungazivula apha nge-ZERO input: yehlisa ifayile kwaye sibona ukuba igama eliyimfihlo lomsebenzisi alinanto, khulula izithintelo, zenziwe. Uninzi lwabakhuphisana basakucela ukuba uchwetheze into, nangona kungekho nto ifunekayo.

Iifayile ezinezitshixo zombini

I-PDF inokuba nazo zombini igama lokugqitha elivuliweyo KUNYE negama eliyimfihlo lomnini elahlukileyo kwiimvume. I-PDF spec ithi NANGONA umntu angavula ngokupheleleyo ifayile. Sikuvumela ukuba ufake nayiphi na into oyaziyo — i-decryptor yethu izama indlela yegama-lomsebenzisi kuqala, emva koko ibuyele kwindlela yomnini-password. Intsimi enye, omabini amatyala aphethwe.

Iifayile apho igama lokugqithisa lingaziwa ngokwenene

Ukuba i-PDF itshixiwe ngumsebenzisi kwaye awulazi igama eligqithisiweyo, akukho sixhobo sisemthethweni sinokuyivula. Uguqulelo oluntsonkothileyo lunamandla ngokwezibalo (AES-256, okanye i-RC4 ebuthathaka kodwa isafuna isitshixo). Izixhobo ezibanga "ukubuyisela" i-password engaziwayo mhlawumbi (a) brute-forcing common passwords, ethatha iintsuku kwaye isebenze kuphela kwiipasswords ezibuthathaka, okanye (b) i-scams. Ukuba ulahlekelwe eyakho i-password, impendulo eyinyani kukucela ikopi entsha kuye nabani na oyithumeleyo - okanye uqhube uhlaselo lwesichazi-magama ngesixhobo esizinikeleyo kumatshini wakho.

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.

Ngubani ovula ii-PDFs?

Ukususa ushicilelo kunye nezithintelo zokukhuphela

Iitemplates zenkampani, iifomu zikarhulumente, kunye nemathiriyeli yezemfundo zihlala zisasazwa ngokuprintwa/ikopi ivaliwe "ukwenzela ukhuseleko" — naxa umxholo ngokwawo ungekho buthathaka. Ukuba ufuna ukuprinta ifom oyifumeneyo okanye ukope ikowuti kwi-PDF oyibambe ngokusemthethweni, yivule kwaye izithintelo azikho.

Eyakho i-password, ulibele

Ukhusele igama eliyimfihlo i-PDF kunyaka ophelileyo, umphathi wephasiwedi akazange ayigcine, kwaye ngoku awukwazi ukuvula ifayile yakho. Ukuba kukho naliphi na ithuba lokuba iqhaga ibingomnikazi-kuphela (ixhaphakile xa ukhuseleko longezwa ngokuthi "cutha ukuhlela" kunokuba "encrypt with password"), yibeke apha — singasivula ngonothi wegalelo. Ukuba sisitshixo sokwenyani somsebenzisi, uya kufuna igama eliyimfihlo.

Ukutyikitya kwakhona isivumelwano esisayiniweyo

Ikhontrakthi ifika itshixiwe yinkqubo yokuhamba komsebenzi yomthumeli. Uyayivula, i-countersign, emva koko uqonde ukuba umbukeli wakho we-PDF akayi kukuvumela ukuba ugcine ngenxa yesitshixo. Vula kuqala, counter-sign yesibini, thumela kwakhona.

Inkcazo ngoxwebhu lwereferensi

Amaphepha ophando, ii-ebooks, kunye neereferensi PDFs ngamanye amaxesha zisasazwa nge-annotation evaliwe. Vula ukongeza amanqaku akho okufunda, ukugqamisa, okanye ujonge amagqabantshintshi ekuhlaleni - amagqabantshintshi akho angaze abelwane abuyele kumthombo wokuqala.

Ukudibanisa nezinye ii-PDFs

Uninzi lwezixhobo zokudityaniswa kwe-PDF ziyala ukuquka ifayile etshixiweyo eyimfihlo, nokuba uyayazi igama eligqithisiweyo. Vula kube kanye, dibanisa ngaphandle kokukhuhlana. Isebenza kakuhle njengenyathelo lokulungiselela phambi kwesixhobo sethu/sokudibanisa-pdf.

Ukugcina ugcino lweenkcukacha zofikelelo lwexesha elide

Uxwebhu olukhuselwe ngegama eliyimfihlo olikhathaleleyo (imbuyekezo yerhafu, ingxelo yezonyango) lelinye igama eliyimfihlo elilityelweyo elikude nelingafumanekiyo. Ngoovimba bobuqu obalawulayo, vula kuqala kwaye ugcine inguqulelo ecacileyo kugcino lwakho olufihliweyo endaweni yokuxhomekeka kwiskim esakhelwe ngaphakathi se-PDF.

Ukufikeleleka komfundi wesikrini

I-PDF "isicatshulwa sofikelelo" ilawula ukuba abafundi besikrini banokufikelela kumxholo wokubhaliweyo. Ii-PDFs ezitshixiwe ngumnini zihlala ziyivalela. Ukuvula kususa uthintelo — okubhaliweyo kuyafikeleleka kwitekhnoloji yokuncedisa.

Ukushicilelwa kwifomati enkulu

Ezinye ii-PDFs zitshixiwe ukuvumela kuphela ushicilelo olukwisombululo esisezantsi. Ukuvula kususa uthintelo, ngoko ungathumela kwiplani okanye umshicileli weefoto ngokunyaniseka okupheleleyo.

Ukuvula amaxwebhu elifa elifihliweyo

Old RC4-encrypted PDFs ukususela ekuqaleni koo-2000 ngamanye amaxesha iyasilela ukuvula ngokucocekileyo kubabukeli bale mihla. Ukuvula kuqhawula uguqulelo oluntsonkothileyo lwelifa kwaye kuphume i-PDF ecacileyo ephathwa nguye nawuphi na umbukeli wale mihla ngaphandle kwengxabano.

Vula i-PDF kwi-iPhone, Android, Mac, Windows, kunye ne-Chromebook

I-PDF unlocker yethu isebenza kwisixhobo ngasinye esinebhrawuza yanamhlanje — Windows, Mac, Linux, Chromebook, iPad, iPhone, kunye Android. Akukho kufakwa kwe-app, akukho plugins, akukho malungelo olawulo. Emva kokuba iphepha lilayishiwe ungaqhawula kwi-intanethi kwaye uqhubeke nokuvula - yonke into isebenza ekuhlaleni nge-Web Crypto API yesikhangeli sakho. Ukufakwa kwegama lokugqithisa kusebenzisa indawo yegama eliyimfihlo, ngoko ke umphathi wephasiwedi yesixhobo sakho unokuzalisa ngokuzenzekela ukuba unenkcaza egciniweyo.

Isebenza Njani ibrowser-Sekwe ku-PDF Ukuvula Ngokwenyani?

I-PDF yakho ifundwe kwinkumbulo yesikhangeli sakho. Ukuba inesichazi-magama se-Encrypt, sicazulula iiparamitha zofihlo (uguqulelo lwe-algorithm, uhlaziyo, idatha yehashi yomsebenzisi/yomnini). Kwi-AES-256 R6 V5, sisebenzisa i-PDF 2.0 yokuqinisekiswa kwegama lokugqitha sisebenzisa i-SHA-256/384/512 kunye ne-AES-128-CBC ukuxuba ukufumana isitshixo sefayile kwi-password yakho, emva koko usebenzise eso sitshixo AES-256-CBC decrypt yonke into efihliweyo. Kwi-RC4 R3 V2, siqhuba i-MD5 ye-key-derivation yelifa kunye ne-RC4 yomsinga-decrypt kwinto nganye. Nje ukuba yonke imijelo ibhalwe ngokucacileyo, siyakha kwakhona i-PDF ngaphandle kwesichazi-magama esifihliweyo. Imveliso ngumgangatho we-PDF 1.7 ovula kuwo wonke umbukeli wale mihla. Yonke i-crypto isebenza kwisiphequluli sakho nge-Web Crypto API - akukho mncedisi obandakanyekayo nakweliphi na inyathelo, kwaye igama lakho eliyimfihlo alize lidluliselwe.

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.

I-PDF yakho evuliweyo ilungile!

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.
