FAQ
What if my PDF has no form fields?
The tool will show a message indicating no fields were found. Only PDFs with interactive AcroForm fields are supported.
Is my PDF uploaded to a server?
No. All processing is done entirely in your browser using pdf-lib. Your file never leaves your device.
Can I flatten the form after filling?
The filled PDF retains editable fields. To flatten (make fields non-editable), use a separate PDF flattening tool.
