How to fill out a PDF form online for free

Quick answerTo fill out a PDF form for free, open it in a browser editor and type into each field with the Add text tool. This works for both interactive forms and flat (non-fillable) forms — for flat forms, you simply drop a text box on each blank line.

Interactive vs flat forms

An interactive form has clickable fields built in. A flat form is just a printed-looking layout with blank lines — most scanned or exported forms are flat, which is why people get stuck trying to type into them.

The Add text approach handles both: you place text exactly where it needs to go, so it doesn't matter whether the form has real fields.

Steps to fill a flat PDF form

Open the form in the editor.
Click Add text and click on a blank line, then type your answer.
Repeat for each field; the text auto-matches the form's font and size so it looks native.
Download the completed form.

Tips for a clean result

Use the same size as the surrounding labels so answers line up.
For checkboxes, add a small 'X' as text, or use a drawing.
Zoom in for precise placement on tight forms.

Frequently asked questions

Can I fill a form that has no fillable fields?

Yes. With the Add text tool you place text anywhere on the page, so flat forms without interactive fields work fine.

Is my filled form private?

Yes, with a local editor. The form is filled in your browser and never uploaded, which matters for forms that contain personal details.
