Is FormFlat free to use without a subscription?

Yes, FormFlat is 100% free with no accounts, no monthly paywalls, and no download watermarks.

Are my confidential files uploaded to any servers?

No. All PDF rendering, form filling, signature baking, and vector flattening happen strictly inside your browser using Web Workers and WebAssembly.

What is PDF flattening and why does it fix the Mobile Blank Bug?

Many mobile viewers (iOS Files, Android, Gmail previews) do not render interactive AcroForm fields properly. FormFlat bakes text and signatures directly into permanent vector content streams, ensuring universal rendering on every device.

Is it safe to type my Social Security Number and birthdate into FormFlat?

Yes, 100%. FormFlat runs entirely inside your browser sandbox via WebAssembly. Unlike online converters that send files to remote servers, FormFlat never transmits your SSN or personal data anywhere.

Will my employer accept an I-9 filled and signed with FormFlat?

Yes. FormFlat exports standard PostScript vector PDFs complying with federal ESIGN and UETA electronic signature standards, stripped of bug-prone interactive AcroForm widgets.
