Frequently Asked Questions

What does flattening a PDF mean?

Flattening a PDF converts interactive elements like form fields, annotations, and comments into static content that becomes part of the document. The content remains visible but can no longer be edited or modified.

Why should I flatten a PDF?

Flattening is useful when you want to finalize a filled form, ensure annotations print correctly on all devices, prevent further editing, or reduce file compatibility issues.

Can I undo flattening a PDF?

No, flattening is permanent. Once a PDF is flattened, the interactive elements cannot be restored. Always keep a copy of the original file before flattening.
