Question 1

Is FormFlat free to use without a subscription?

Accepted Answer

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

Question 2

Are my confidential files uploaded to any servers?

Accepted Answer

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

Question 3

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

Accepted Answer

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.
