Frequently asked questions

What does flattening a PDF mean?

Form fields and comments sit on top of the page as separate, editable objects. Flattening draws their current look into the page itself and removes the editable layer, so what you see can no longer be changed.

Which mode should I use?

“Flatten forms and comments” keeps the text sharp, selectable and small. “Convert pages to images” guarantees nothing can be edited or copied, but text can’t be searched and the file is usually larger.

Why was a government portal rejecting my filled form?

Some portals reject PDFs that still contain fillable fields or show them empty. Flattening fixes this because the values become part of the page.

Is my file uploaded anywhere?

No. Everything happens inside your browser, so bank statements, ID proofs, contracts and forms stay on your device.
