Flatten PDF
Make supported interactive form fields into regular page content without an upload.
Make form fields non-interactive
Filled AcroForm appearances become visible page content. Flattening does not certify or cryptographically secure the result.
What happens to my PDF?
The document never leaves this browser tab for this tool. Your device performs the work with locally hosted PDF components. No login is required. We collect limited technical events but not document contents.
Can I use this tool on a mobile phone?
Yes, for compatible PDFs. Very large files and scanned pages may be slower or run out of memory on older devices. For heavy conversions, a desktop browser may be more comfortable.
Options and limitations
Save supported form fields as fixed page content. The downloaded fields are no longer interactive. This does not promise flattening every annotation type and does not add password protection.
How to use
Choose your input, adjust the available settings, review the result and download or copy it.
