Frequently Asked Questions
1What does flattening a PDF do?
Flattening converts interactive elements (form fields, annotations) into static, non-editable content — like printing to paper.
2Can I flatten only form fields?
Yes. Choose to flatten forms only, annotations only, or both. JavaScript removal is also available.
Why Use ZiaSign's Flatten PDF Tool?
ZiaSign's free PDF flattener converts interactive elements into static content. Form fields become plain text, annotations become part of the page, and JavaScript is removed. The result is a clean, non-editable PDF that displays identically on any device. Perfect for finalizing documents before distribution. No watermark, no signup.
