What does flattening a PDF do?

Flattening merges interactive form fields and annotations into the static page content, making them non-editable.

No. Flattening runs securely in your browser without uploading.

When should I flatten a PDF?

Flatten before sharing a form to prevent recipients from editing the filled values, or before printing to ensure all annotations are visible.
