Check & Remove PDF Encryption

Upload a PDF to instantly check whether it is encrypted or password-protected. If the file can be opened by pdf-lib (identity encryption or open), click to remove the protection and download a clean copy. All processing happens in your browser.

Why can't I add a password?

[email protected] does not support AES encryption via its save() API. Full password-adding support requires a commercial SDK like Apryse or Nutrient.

What is identity encryption?

Some PDFs are flagged as encrypted but use an identity (null) cipher — they don't actually restrict content. pdf-lib can open and re-save these without the encryption flag.
