Common questions

Frequently Asked Questions

What does flattening a PDF do?

Flattening converts interactive elements (form fields, annotations) into static, non-editable content — like printing to paper.

Can I flatten only form fields?

Yes. Choose to flatten forms only, annotations only, or both. JavaScript removal is also available.

Will flattened form data still be visible?

Yes. All filled-in data becomes static text on the page — visible but no longer editable.

Why flatten a PDF before sharing?

Flattening prevents recipients from changing form data, ensures consistent rendering, and removes potential security risks from interactive elements.

Does flattening reduce file size?

It can slightly reduce file size by removing form field definitions and JavaScript. For significant size reduction, use the compress tool.
