PrivatePDF Local

Flatten PDF privately.

Flatten PDF by PrivatePDF lets you flatten pdf forms and comments into permanent page content locally, so what you see is exactly what everyone else will see entirely in your web browser. Processing happens entirely in your browser — your file bytes are never sent to PrivatePDF's servers. Nothing is uploaded. There is no account, no watermark, and no file-size limit imposed by the platform.
