Fill and Sign PDF: what you need to know
Fillable PDF forms have boxes you can type into, but many phone and browser viewers won't let you save what you typed. FilesForU shows every field as a simple form — type your answers, tick boxes, choose options — and saves them into the PDF.
Then click Continue with Sign PDF on the result page to add your signature. You can also flatten the form so the answers can't be changed later.

Questions & answers
My PDF has no fillable fields — what can I do?
Use Edit PDF to type text anywhere on the page, then Sign PDF to sign it.
What does Flatten mean?
Flattening turns your answers into normal page content so they can't be edited by the next person.
Are my answers sent anywhere?
No. The form is filled in on your device.
Are my files uploaded to your server?
No. This tool runs entirely inside your browser, so your files stay on your device. FilesForU never receives, stores or sees them.
Is it really free?
Yes. Every tool is free with a free account — no daily limit, no watermarks, and files up to 500 MB.
