Fill PDF
Fill form fields, then save or flatten.
Runs on your device. Files are never uploaded.
The tool reads every interactive field in the PDF — text, checkboxes, radio groups, dropdowns and lists — and lets you fill them. Save it as an editable form or flatten it so the answers cannot be changed.

Questions
My PDF shows no fields. Why?
The form is probably a flat scan without interactive fields. Use Edit PDF to type text on top of it instead.
Are my files uploaded to a server?
No. The tool runs in your browser using your own device. Your file is never sent to us or anyone else — you can even disconnect from the internet after the page loads.
Is it really free?
Yes. There is no account, no watermark and no daily limit.
Is there a file size limit?
There is no fixed limit. Very large files depend on your device memory — a modern phone or laptop handles files of several hundred MB.
