A password-protected PDF stops you from opening, copying, printing or editing it until you enter the right password. If you know the password, removing it takes 30 seconds. If you have forgotten it, there are legitimate recovery paths for documents you own. This guide covers both situations, including what to do when a PDF has permissions restrictions rather than an open password.
Table of Contents
Two Types of PDF Passwords — Which One Do You Have?
| Open Password | Permissions Password | |
|---|---|---|
| What it does | Blocks opening entirely — password prompt before any content | PDF opens freely but Print, Copy and Edit are blocked |
| How to tell | Password box appears immediately on opening | PDF opens but toolbar buttons are greyed out |
| To unlock | You need the correct password | Can often be removed without the password |
| Common source | Confidential documents, financial files, contracts | E-books, forms, read-only shared documents |
If the PDF opens normally but Print and Copy are greyed out, you have a permissions restriction — not an open password. The solutions differ for each type.
How to Unlock a PDF Free (You Know the Password)
- Open the PDF Unlock tool and upload your PDF.
- Enter the password when prompted.
- Download the unlocked PDF — opens on any device with no password required.
No account required, no watermarks. File deleted automatically after download. For highly sensitive documents, use the Mac Preview method below so the file never leaves your device.
How to Remove PDF Permissions Restrictions
- Online unlock tool: Upload to the PDF Unlock tool — handles permissions restrictions automatically without needing the permissions password.
- Print to PDF (any device, no upload): Open the restricted PDF in Chrome or Edge → Ctrl+P (Cmd+P on Mac) → Save as PDF → Save. Works because the browser re-renders the page, bypassing the permissions layer entirely.

Forgotten Your Password? Recovery Options
- Password manager — check LastPass, 1Password, Bitwarden, or browser saved passwords first.
- Original email — search your inbox; password is often in the delivery email.
- Common variations — date of birth (DDMMYYYY), account number, document date. Bank PDFs commonly use one of these.
- Contact the sender — banks and accountants can confirm the format or re-issue the document.
- Recovery software (your own files only) — tools like Passper for PDF use dictionary methods for documents you own.
When You Cannot Unlock a PDF
- Unknown open password: A properly encrypted PDF with an unknown password cannot be opened by any free tool.
- Documents you do not own: Bypassing security on a PDF you have no authorisation to access is illegal under computer misuse laws in most countries.
How to Re-Protect a PDF After Unlocking
- Use the PDF Password Protect tool to apply a new password.
- Use at least 12 characters with letters, numbers and symbols.
- Record it in a password manager immediately.
- Send the password separately from the PDF — never in the same email.
Frequently Asked Questions
Can I unlock a PDF without the password?
Only if it has permissions restrictions. The browser Print-to-PDF method removes those without any password. An unknown open password cannot be bypassed by any free tool.
Is it legal to unlock a PDF?
Yes — for documents you own or have authorised access to. Bypassing security on a document you are not authorised to access is illegal in most countries.
Will unlocking change the content?
No. All content, formatting, images and text stay completely unchanged.
My bank PDF is password protected — what is the password?
Bank PDFs are commonly protected with your date of birth (DDMMYYYY), PAN number, or account number. Check the delivery email or call your bank for the exact format.
Why is the PDF still asking for a password after unlocking?
Your device may be opening the original cached file. Open the newly downloaded file directly from your Downloads folder.
Can I unlock a PDF on my phone without an app?
Yes. iPhone: Files → open → Share → Print → pinch-zoom → Save to Files. Android: Chrome → Print → Save as PDF. Both work without any app.
The Short Version
If you know the password: upload to the PDF Unlock tool, enter it, download — 30 seconds. On Mac, Preview does this locally with no upload. On any device, opening a permissions-restricted PDF in Chrome and printing to PDF removes restrictions without any password. If forgotten, check your password manager and original email first, then contact the sender. After editing, re-protect the PDF and store the new password in a manager immediately.
