About this calculator
If you do not have the password, this page will fail. We do not brute-force. The export is a raster rebuild, so text may become an image.
How It Works & Formula
Formulapdf.js with your password, then raster rebuild — no cracking
pdf.js getDocument({ password }) then JPEG pages into a new pdf-lib file.
Frequently Asked Questions
Can you crack a PDF I forgot the password for?
No. Type the user or owner password you already know. There is no brute-force and no rainbow table.
Why did the text become an image?
The export rebuilds each page as JPEG so the password flag is gone. Searchable text may be lost; that is the honest tradeoff without writing encryption dictionaries.
