Does this work with all PDF forms?

It works with standard AcroForm PDFs (the most common type). XFA-only forms — used by some government agencies — are not yet supported.

What does 'flatten fields' mean?

Flattening converts form fields into static page content. The output looks identical but recipients can't edit the values.

No. Everything happens in your browser — values, file contents, and the download are all local.

Type into PDF form fields, tick checkboxes, pick dropdown values — all in your browser. Optionally flatten so the output can't be re-edited.
