How to: Fill PDF Form

  1. Select a PDF form.
  2. Click into fields on the page and type – or click anywhere to add text.
  3. Download the filled PDF (optionally flattened).

Printing a form just to write on it and scan it back is a waste of time. Fileopia shows your PDF and places live inputs exactly over every field – text boxes, checkboxes, radio buttons, dropdowns – so you fill it like a web form. Scanned or non-fillable forms work too: blank lines are detected automatically and you can click anywhere to add text.
