About this tool
Use the current PDF password to render authorized pages locally and build a fresh unencrypted flattened PDF.
This workflow does not crack, recover, or guess passwords.
Flattening intentionally trades document structure and interactivity for a portable unencrypted visual copy.
Frequently asked questions
Can this crack an unknown PDF password?
No. You must supply the current password. The tool does not guess, bypass, recover, or remove an unknown credential.
What does flattening remove?
The new PDF retains page appearance as images but loses selectable text, links, forms, annotations, signatures, attachments, bookmarks, layers, and accessibility structure.
Is the password sent to a server?
No. PDF.js opens and renders the file locally in your browser, and the password is not transmitted by this workspace.
