Questions people ask
What happens if the PDF has no form fields?
Nothing changes — the file downloads as-is, since there's nothing to flatten.
Can I un-flatten a PDF later?
No — flattening is permanent. Keep a copy of the original if you might need editable fields again.
Is my file uploaded anywhere?
No — flattening happens entirely in your browser.
