# Remove a PDF's password

> Remove the password from a PDF you can open, so you don't have to type it every time. Free, in your browser: the file and the password are never uploaded.

Type the password once and get a copy of the PDF that opens without it.

## Key facts

- **Price:** Free, no sign-up, no watermark
- **Upload:** Never: the file is processed on your device
- **Works on:** Any recent browser on a computer, iPhone, iPad or Android
- **Files:** Up to 400 MB per PDF on a computer, 150 MB on iPhone and iPad. Larger files depend on your device's memory.
- **Updated:** October 4, 2026

Unlock PDF opens your protected file with the password you type and saves a copy without encryption. It is meant for your own files: it removes a password you know, it never guesses or cracks one. PDFs that open freely but only restrict printing or copying are left as they are.

## How it works

1. Drop the protected PDF.
2. Type its password.
3. Select Unlock PDF and download the copy without a password.

## Supported files

Input: one password-protected PDF. Output: the same PDF without encryption.

Up to 400 MB per PDF on a computer, 150 MB on iPhone and iPad. Larger files depend on your device's memory.

## When to use it

- Stop typing the password of a bank statement or payslip every time you open it.
- Prepare a protected PDF before merging, compressing or signing it.
- Archive documents in a form any app can open and index.

## Quality and limitations

- You need the password: the tool does not crack or bypass it.
- Usage restrictions on PDFs that open without a password are not removed.
- The unlocked copy is no longer protected: store it carefully.

## Common issues

- **“Wrong password.”:** Passwords are case-sensitive. Check capitals and the keyboard layout, then try again.
- **“This PDF has no password.”:** It already opens freely; there is nothing to remove.

## Private by design

This tool runs entirely in your browser with JavaScript. Your file is read and processed on your device and is never uploaded to a server. Closing the tab discards everything.

## Frequently asked questions

### Can you open a PDF if I forgot its password?

No. Unlock PDF only removes a password you know; it never tries to guess one.

### Is my password sent anywhere?

No. The file is decrypted in your browser; nothing is uploaded.

### Is the content changed?

No. The pages stay exactly as they are; only the encryption is removed.
