Why use this tool

  • Looks the same everywhere

    Flattened forms print and display identically in every viewer, including ones that ignore form fields.

  • Prevents changes

    Values can no longer be edited in a form field, which is useful before sending a signed form.

  • Processed locally

    Your form data stays on your device — nothing is uploaded.

Frequently asked questions

What does flattening a PDF mean?

Interactive elements — form fields and annotations — are drawn permanently onto the page and the interactive versions are removed.

Do links still work after flattening?

Yes. Links are kept; only form fields and markup annotations are flattened.

Can I undo flattening?

Not in the flattened file. Keep the original if you might need to edit the form again.
