About this tool: Unlock PDF
Open a password-protected PDF with the correct password, render each page and rebuild an unlocked visual copy locally. The flattened output does not retain selectable text, links or form fields. Remove an opening password by rendering and rebuilding a flattened unlocked PDF copy.
How it works
PDF.js opens the encrypted PDF with the supplied password, renders each page locally, and pdf-lib rebuilds a new unencrypted document from those rendered pages.
Practical example
Provide the correct password for a protected statement and create an unlocked flattened copy for a workflow that does not require selectable text.
Important notes
The password must be known. The output is flattened, so links, form fields and selectable text are not retained.
Privacy & processing
The password and PDF stay in your browser and are not sent to a NexterHub server by this workflow.
