How to Fill Out a PDF on a Phone
To fill out a PDF on your phone, choose the file in your browser, place the requested information on the page, check the result, then share or download the completed copy. This works when a PDF is flat or scanned and its printed lines do not respond when you tap them.
Choose a PDF from your phone
Open a PDF you have saved or received, then select the pages you need to complete.
Use touch to place visible answers
Add text, checks, dates, handwriting, and a drawn signature where the form needs them.
Zoom in for small fields
Use two fingers to zoom and pan while you position an answer, initial, or signature mark.
Know what the editor changes
JustFillForm adds visible content over rendered PDF pages. It does not edit original PDF text or turn a flat PDF into interactive fields.

What Happens to a PDF You Choose on Your Phone
