Important limitations

Only supported form fields are handled. If no supported interactive fields are found, the tool may return an error. Save a copy first.

Privacy and file handling

This tool is designed to process supported files locally in your browser; the static website does not provide server-side file storage. Your browser still downloads the JavaScript libraries required for some operations from third-party content delivery networks. See the Privacy Policy for details. Do not use the output without checking it, and keep your original file.

Frequently asked question

Flattening can make fields non-editable, so keep an editable original in case corrections are needed.
