Frequently asked questions
Why can't I see any fields?
The PDF has no interactive fields; it may be a scan or a flat document. Use Edit PDF to type text onto it instead.
Should I flatten the form?
Flatten when you're sending the final version: answers become part of the page. Leave it unflattened if someone still needs to edit it.
Are my files uploaded?
No. Fill PDF Form runs entirely in your browser: your files are processed on your device and never sent to a server.
Is it free?
Yes. It's free, with no sign-up, no watermarks and no daily limits.
Is there a file size limit?
There's no upload limit, because nothing is uploaded. Very large files are limited only by your device's memory.
