Why Flatten a PDF?
Flattening removes editable form fields, comments, and layers — converting everything into a single, unchangeable image. This ensures your file looks exactly the same for everyone and can’t be altered by mistake.
- Lock in content: Prevent accidental edits or data changes.
- Ensure print fidelity: Make sure documents look identical on paper or screen.
- Protect signatures: Merge e-signatures and annotations permanently into the file.
- Improve compatibility: Ideal for uploads, archiving, and e-signature platforms.
Tools Oasis flattens your PDFs instantly — no uploads, no tracking, and no limits.
