We only remove passwords you provide — we never crack unknown ones.
Enter the PDF's password
Unlocking a PDF means removing the password requirement so the file can be opened, edited, or shared without the encryption layer. This only works for PDFs you have legitimate access to — you provide the password, and we strip it. We do not crack unknown passwords, and we do not bypass authentication on files you don't own. Use this tool when you've forgotten you encrypted a file (and remember the password), when a vendor sends you a password-protected report you need to keep working with, or when you need to remove a legacy password from your own archive.
How to unlock pdf step by step
- 1
Upload the password-protected PDF
Drop the encrypted PDF on the upload area. The file uploads encrypted-as-is — we can't open it yet without the password.
- 2
Enter the current password
Type the password in the field below the dropzone. We use it once to decrypt the file in an isolated worker, then discard it. The password is never stored, logged, or transmitted to any third party.

Click Unlock and download
We use qpdf to remove the encryption layer. The output is a standard PDF that opens in any reader without a password.
Why unlock pdf on PDFOnly
We never crack passwords
If you don't know the password, we won't help you bypass it. This is by design — we only unlock files you have rightful access to.
Password is discarded immediately
Your password lives in memory just long enough to decrypt your file, then it's gone. Not logged, not stored in any database, not used for analytics.
Handles every PDF encryption standard
AES-256 (modern Acrobat), AES-128 (older Acrobat), RC4 (legacy 1990s/2000s PDFs) — all supported.
What people use unlock pdf for
A few common scenarios. If your workflow looks like one of these, this tool is a good fit.
Re-edit a protected document you own
You password-protected a contract draft last quarter. Now you need to update it but your editor refuses without the password each time. Unlock it once, edit freely, re-protect when done.
Combine multiple protected PDFs
PDFs need to be unlocked before they can be merged. Unlock each one (with its password), then run them through Merge PDF to combine.
Process a vendor-encrypted report
Your accountant sends a quarterly report encrypted with a shared password. Unlock it once so you can search, copy figures, or extract pages without re-entering the password each time.
Migrate a password-protected archive to a new system
Some document management systems can't ingest encrypted files. Unlock them in bulk before importing.

Frequently asked questions
Can you unlock a PDF without the password?
No. We only strip passwords you provide — we never crack or bypass passwords you don't know. This is by design. Strong PDF encryption (AES-256 with a long password) is computationally infeasible to break, and we don't pretend otherwise.
Is unlocking a PDF legal?
Yes — for files you own or have explicit permission to access. Unlocking a PDF you have no right to access is unauthorized access and may be illegal. Don't use this tool to bypass protections on copyrighted material or other people's documents.
What if the PDF only has an owner password (not a user password)?
If the PDF has only an owner password (preventing edits/printing but not opening), some readers can ignore it. We still ask for the password before unlocking — it's the cleanest way to ensure the file's content is fully editable afterward.
Do you support legacy RC4-encrypted PDFs?
Yes. Older PDFs from the 1990s/2000s often use RC4 40-bit or 128-bit encryption. qpdf handles those alongside modern AES.
What happens to the password I enter?
It's transmitted to our server over HTTPS, used once to decrypt your PDF in an isolated worker, then discarded. It's never written to disk, never logged, never stored in our database.
What if the unlock fails?
Most common reason: the password is wrong (case-sensitive, watch for trailing spaces). If you're sure the password is right, the PDF may use an older encryption standard we don't auto-detect — contact us with the file and we'll diagnose.
Can I unlock multiple PDFs at once?
Through the web UI, one at a time (each has its own password). Pro plan includes API batch unlocking — POST a list of {fileId, password} pairs to /v1/tools/unlock-pdf and get all unlocked files back.
