Open the tool to process a copy of your document in your browser, with no account required.
Open Flatten PDF Forms →Always open the downloaded file once and confirm that the result looks correct before sharing it.
The tool is designed to process selected files in your browser rather than sending them to a PDF upload server. Keep your original file until you have checked the result.
The file must contain supported interactive form fields. Flattening is not encryption, secure redaction, or tamper-proof legal evidence. Keep the original editable copy.

Flattening a PDF form turns interactive fields into a more fixed page appearance. This can help preserve completed fields when a document is viewed or printed in different PDF apps.
It is useful for final copies of forms and submissions where recipients mainly need to view or print completed information. Flattening may remove interactive editing.
Select a PDF containing supported form fields, run the flattening tool and save the result. Reopen the file to confirm values, checkboxes and layout.
Keep an editable copy before flattening. Flattening is not the same as encryption, a digital signature or secure redaction.
Why might a form not work? The PDF must contain supported interactive fields. Can flattened fields remain interactive? Usually not, so retain the original.
