Frequently asked questions

Why flatten a PDF?→

Flattening removes interactive form fields and annotations so the PDF can't be edited through them. Note that it removes them rather than printing their contents onto the page, so typed form values and comments are not kept. To keep them visible, print to PDF from your PDF viewer instead.

Can I keep the original editable file?→

Yes. File Studio exports a flattened copy and leaves your source file available.

Does flattening upload my PDF?→

No. It runs locally on your device.
