UNLOCK PDF
Remove PDF password free unlock with your password
With the password you already know, remove a PDF’s opening password.
Enter the current password of your own PDF once, and save a copy that opens without asking. Files and passwords are never uploaded, and before saving, the result is reopened without a password and checked against the original, text and images.
- No install
- No sign-up
- No upload
In short Unlock PDF is a free web tool that removes the password from your own PDF using the password you already know, then reopens it without a password so you can check text and images before saving. It runs in your browser with no install or sign-up, and your files are processed in this device’s browser — never uploaded to a server. Up to 6 standard password-protected PDFs sharing one password, 20MB each, 50MB and 200 pages in total. It can’t unlock a file without its password, and permission-restricted files need the owner password.
BEFORE → AFTER
A payslip that asked for a password every time now just opens
Our 2-page payslip with an opening password (16,643 bytes) won’t open without it. We ticked “These are my files and I am allowed to remove their passwords,” entered the current password and pressed “Unlock and check.” The result card read “2 pages preserved · opens without password · text and images checked.” Reopening the saved PDF (15,587 bytes) outside the tool without a password, both pages opened and the text, down to the name and the net pay of $3,471.57, matched the original.
Actual result of unlocking a payslip for a fictional employee, “Mary Major” (company, name and amounts are examples; the password is a test one for this guide), with Unlock PDF v0.1.9, then reopening the saved PDF without a password. Checked in Edge on Windows; real iPhone and Mac Safari have not been checked yet.
