Actually Free PDF Flattener

Flatten a PDF free: turn form fields, comments, highlights and stamps into ordinary page content so they cannot be changed. No upload.

What it does

ActuallyFreeTools flattens PDFs for free. “Form fields” converts filled-in fields into ordinary page content while keeping text sharp and selectable. “Everything” redraws each page so comments, highlights and stamps are baked in too. Flattening stops answers being edited and makes the file look the same in every viewer. Nothing is uploaded.

How to use it

  1. Drop the PDF.
  2. Choose Form fields or Everything.
  3. Flatten and download.

Questions people ask

Why flatten a form?

So the answers cannot be changed after you send it, and so every viewer shows exactly what you see.

Is flattening reversible?

No — keep the original if you may need to edit it again.

Does it remove hidden text?

No. To destroy sensitive content, use the PDF editor’s Redact tool.

Is Flatten PDF on ActuallyFreeTools really free?

Yes. There is no sign-up, no daily limit, no watermark and no paid tier. Nothing is held back for paying users.

Are my files uploaded anywhere?

No. Flatten PDF runs inside your browser, so your files are processed on your own device and never sent to a server. That is also why there is nothing to meter or charge for.
