Unlock PDF
If you have the password to a PDF (or it's only locked with owner restrictions), this tool re-saves it without the password so you can edit, print, copy, or process it freely. Runs in your browser.
Why unlock a PDF?
- Re-saving a bank or utility statement (which often arrives password-protected with your account number) so you can archive it without re-typing the password every time.
- Removing 'no copy / no print' owner restrictions from a PDF you legitimately own and need to extract text from.
- Cleaning up a stack of password-protected PDFs into an unprotected archive for a personal records folder.
- Removing the password from a PDF before passing it through another tool that doesn't support encrypted inputs (some email scanners, OCR pipelines, or older PDF viewers choke on passwords).
- Unlocking a contract that arrived with a 'do not edit' restriction so you can fill in fields or add signatures.
How it works
If a password is provided, the PDF is loaded with pdf-lib using that password to decrypt. If no password is provided (or the document only has owner-level restrictions, not user-level encryption), the PDF is loaded with pdf-lib's ignoreEncryption flag, which bypasses owner restrictions like print/copy/edit blocks. Either way, the loaded document is re-saved without any password or encryption applied, and downloaded. Important caveat: pdf-lib can decrypt PDFs using older RC4 and AES-128 schemes; some modern AES-256-encrypted PDFs may not decrypt successfully — those will need a desktop tool like qpdf or Adobe Acrobat.
Frequently asked questions
Can this break a password I don't know?
No, and that's by design. PDF passwords use real cryptography — without the right password, the content can't be decrypted. If you've forgotten the password, your only options are recovery from where you got the PDF (your bank, your accountant, etc.), or specialised desktop tools that brute-force weak passwords. Tools that claim to remove unknown passwords either silently fail, only work on owner restrictions, or are scams.
What's the difference between user and owner passwords?
User passwords (also called 'open passwords') are required to view the PDF at all — without it, the file is encrypted and unreadable. Owner passwords (also called 'permission passwords') let you open and view the PDF freely but block actions like printing, copying text, or editing. This tool can remove both types — user passwords need the password entered; owner restrictions are stripped automatically.
Will the unlock work on every PDF?
Most. pdf-lib supports the common encryption schemes you'll see in real-world PDFs (RC4-40, RC4-128, AES-128). Some PDFs with the newer AES-256 encryption (PDF 2.0, used by some enterprise systems) may not decrypt cleanly — for those, qpdf or Acrobat is the right tool.
Is this legal?
Removing protection from PDFs you own or legitimately need to access (your own bank statements, contracts you've signed, personal records) is fine. Stripping protection from someone else's copyrighted material to redistribute is not. Use your judgement; we're a tool, not a court.
Are my files uploaded?
No. The PDF and password stay in your browser; pdf-lib decrypts and re-saves locally.
About this tool
PDF passwords are the most common 'lightweight' protection in business workflows — banks send statements password-protected with the last four digits of your SSN, employers send onboarding packets locked with employee ID, schools send transcripts locked with date of birth. The protection is real cryptography (so a forgotten password really is gone), but for documents you legitimately own, the password is just friction — you re-type it every time you open the file. Unlocking the PDF (with the known password) once and archiving it unprotected is a normal personal-records operation. Doing it client-side via pdf-lib avoids uploading sensitive financial or HR documents to a third-party SaaS just to strip a password you already know.
