FAQ
What does flattening a PDF mean?
Flattening merges all form fields, annotations, and layers into the base content, making them non-editable and part of the page background.
Why should I flatten a PDF?
Flattening prevents accidental edits, ensures consistent appearance across viewers, and can reduce file size.
Can I undo flattening?
No, flattening is permanent. Always keep a backup of your original PDF before flattening.
