Optionally flatten supported form fields so values stay in the exported file.
Fill and export forms in the browser without app-server document uploads.
Flattening is useful when a filled PDF should be sent as a stable copy rather than a form that keeps editable fields.
PDF form support depends on how the source file was built. Some forms are simple AcroForms, while others are scans or complex documents that need manual annotations instead.
