Flatten PDF FAQ
Can I edit form fields after flattening?
Flattening is intended to make interactive elements fixed. Keep the original unflattened PDF if you may need to edit those fields later.
Do I need to install software for Flatten PDF?
No. TapScanner runs in a modern web browser, so you can upload, process, and download the result without installing desktop software.
