Is FormFlat free to use without a subscription?

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

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.

What is PDF flattening and why is it necessary?

PDF flattening merges all interactive elements (form fields, checkboxes, digital signatures) directly into the page vector layer. This prevents anyone from editing your values and ensures that mobile viewers (iOS Files, Android Gmail) do not display an empty form.

Does flattening reduce the quality of my document?

No! Unlike tools that take a raster screenshot (creating blurry pixelated text), FormFlat compiles mathematical PostScript vector curves and Helvetica typography, maintaining 100% crispness at any zoom level.
