Question 1

What does flattening a PDF do?

Accepted Answer

Flat PDF re-renders each page as an image-based page and creates a new PDF, which removes selectable text and most editable overlays.

Question 2

Are my PDF files uploaded to a server?

Accepted Answer

No. Flat PDF processes the document directly in your browser, so there is no upload step.

Question 3

Is Flat PDF free to use?

Accepted Answer

Yes. The app is free to use and returns a downloadable flattened PDF after processing finishes.
