What does flattening a PDF do?

Flattening bakes interactive elements like form fields, checkboxes, annotations, and comments into the static page content so they can no longer be edited or removed.

When should I flatten a PDF?

Flatten before sharing a filled form to prevent recipients from changing answers, or after adding a watermark or signature to lock it in place permanently.

Is flattening reversible?

No. Once a PDF is flattened, the interactive elements are permanently merged into the page content and cannot be restored. Always keep a copy of the original.

How to flatten a PDF

Flattening bakes form fields, annotations, signatures, and transparent layers into the static page content so they can't be moved, edited, or removed.

Use this when a PDF needs to look identical for every recipient, regardless of which reader they open it in.
