What can the PDF password remover do?
The PDF Password Remover opens a supported encrypted PDF with a password supplied by an authorized user and rebuilds an unprotected copy locally. It is intended for documents you own or are permitted to modify when the password is known and repeated entry is no longer required.
Pdf.js handles password-aware reading and pdf-lib creates the new file in the browser. The tool does not recover or crack forgotten passwords, cannot support every encryption variant, and cannot add a new password because the current writer lacks PDF encryption support. Removing protection may also affect signatures and document features.
