PDF password checker

Enter the password for a PDF you own or are authorized to open. This tool confirms whether the password is correct. It does not crack, guess, or bypass passwords, and it cannot save a password-free copy of an encrypted PDF.

PDF files only. Browser processing supports files up to 50 MB.

You need the correct password for encrypted PDFs.

What this tool returns

A pass or fail result for the password you enter, plus the page count when the PDF can be read.

How PDF password checking works

Some PDFs are encrypted and require a password to open.
The checker tries to open the PDF with the password you supply.
If the document opens, the password is correct and the page count is shown.
Browser PDF libraries can read an encrypted PDF but cannot re-save it without encryption, so no unlocked copy is produced.
Not all PDF encryption types are supported by browser libraries.
Checking a password is not the same as bypassing access controls.

User password vs owner permissions explained

A user password is required to open the PDF.
Owner permissions may restrict printing, copying, editing, or page changes.
Removing restrictions should only be done when authorized.
Some PDFs have both user password and owner permission restrictions.
PDF libraries differ in what they can read, modify, or save.
This tool checks the open password only. It does not report or change owner permissions.

Encryption, passwords, and authorization notes

Encrypted PDFs protect access to content.
The correct password is required.
This tool does not guess passwords.
Forgotten passwords cannot be recovered by this tool.
Only check files you own or have permission to access.
Sensitive PDFs should be handled on trusted devices.
Keep original files before saving modified copies.

Privacy and local processing notes

This implementation checks PDFs locally in the browser using PDF.js. No account is required, and this page does not upload your PDF or password. Passwords are never logged or stored. Your file is only read in memory to test the password, and nothing is written or downloaded. Avoid selecting sensitive PDFs unless you trust the device and browser.

Method explanation

1. Select or drag a PDF into the tool.
2. Validate that the file is a PDF.
3. Detect whether the PDF is encrypted at all.
4. Enter the password for a PDF you own or are authorized to open.
5. Attempt to open the PDF in memory using that password.
6. Report a pass or fail result, plus the page count when readable.
7. Show clear errors for wrong passwords, unsupported encryption, or damaged files.
