Flatten PDF
Merge form fields, annotations, and comments into a static, non-editable PDF.
Merge interactive form fields, annotations, comments, and digital signatures into a static, non-editable PDF layer. Flattening is essential before archiving forms, submitting completed applications, or sharing filled documents where recipients should not modify the content.
The flattened PDF looks identical to the original but all interactive elements become permanent, static content. This also reduces file size and ensures the document displays consistently across all PDF viewers and printers.

Frequently Asked Questions
How to Flatten a PDF
Flattening converts interactive form fields, annotations, and comments into static, non-editable content. The result is a "print-ready" PDF where all layers are merged into one. This prevents recipients from modifying form entries or annotations after submission.
- Upload your PDF with form fields or annotations.
- Click "Flatten PDF" to merge all layers.
- Download the flattened, static document.
Flattening is essential when submitting completed forms, archiving signed contracts, or sharing annotated documents where you do not want the recipient to modify anything. The visual appearance stays identical, but form fields become plain text and annotations become part of the page.
Frequently Asked Questions
What does "flatten" mean?
It means merging all interactive layers (form fields, annotations, comments) into a single static layer that cannot be edited.
Can I un-flatten a PDF?
No. Flattening is irreversible. Keep a copy of the original if you need the editable version.
Will the appearance change?
No. The document looks exactly the same — only the interactivity is removed.
