Stop Printing PDF Forms to Fill Them Out

We've all been there: you receive a PDF form on your phone, but you can't fill it out. The old solution? Print it, fill it out by hand, scan it, and email it back. That's time-consuming and requires access to a printer and scanner.

BoostPDF lets you fill out PDF forms directly on your phone. Add text to form fields, place checkmarks in boxes, and sign with your finger—all in your mobile browser. No app to download, no printer needed, and you can complete forms anywhere in minutes.

Three Essential Tools for Filling Forms on Mobile

BoostPDF provides everything you need to complete PDF forms on your phone:

Text Tool
Tap the Text tool and then tap anywhere on the form where you need to enter information. Your phone's keyboard will appear. Type names, addresses, dates, or any text required. You can adjust font size and color as needed.

Form Tool
The Form tool includes checkmarks, X marks, circles, and other symbols for filling boxes and selecting options. Tap the Form tool, choose your symbol (checkmark, X, circle, etc.), then tap the box or field you want to fill. Perfect for multiple-choice questions and checkbox selections.

Signature Tool
When forms require your signature, tap the Signature tool. Draw your signature directly on your phone screen with your finger, or type your name and select a signature style. You can save your signature and reuse it on future forms.
