How to fill out a PDF form on any device

You don't need to print, write and scan. Here is how to fill any PDF form on a computer or phone and send it back cleanly.

Open the tool: Fill PDF Form Online

1. Check whether the form is fillable

Open it here. Blue boxes mean fillable fields. No boxes means a flat or scanned PDF, which you can still fill with Add text and Add tick.

2. Fill, check and save

Work top to bottom with Tab, use Next empty field for gaps, and read the form once more at a higher zoom before saving.

3. Send it the right way

  • Email or upload portals: send the saved PDF as it is.
  • Forms that must not change: tick Lock answers before saving.
  • Recurring forms: export your answers and keep the file.
  • Need a signature: add it in the PDF editor afterwards.
