How it works
Current form field values are embedded into page content. The fields are no longer interactive in the resulting copy, but a PDF editor can still modify the document.
Common use cases
Locking a filled-in administrative form (URSSAF, tax return, application) before sending it, so the recipient can't change the numbers.
Freezing a signature placed in a signature field so it can't be removed by re-opening the form.
Preparing a completed contract for archival — many archive systems require flattened forms.
Privacy — This tool runs entirely in your browser. Your PDF is never uploaded to our servers — the file stays on your device from start to finish.
Frequently asked questions
When should I flatten a form?
When you want to share a copy without interactive fields. Keep the original if you still need to fill in or correct the form.
Does it prevent all document changes?
No. Flattening does not encrypt the document or prevent a PDF editor from changing page content.
