When to use this tool

Upload a reviewed PDF and flatten supported form fields and annotations into static page content. Keep the interactive original.

A practical example

Create a static copy of a filled application when the recipient does not need editable fields.

Check the exported result

Reopen the result and check that all field values, checkboxes and visible annotations remain legible.

Common problems and limits

Flattening reduces editability and is not equivalent to redaction. It may invalidate an existing digital signature.

Choose the next step

PDF Forms fills supported fields before the flattening step.

Files, privacy and saving

This workflow uses temporary server processing after your consent. Review the upload notice and avoid processing material you are not authorised to use. Keep your original, review the downloaded result and choose a clear filename before sharing it. The privacy policy explains the processing approach.
