Turn your PDF into an interactive form by adding text fields and checkboxes that recipients can complete.

Use this tool for free as often as you need. The document is processed on your device so its contents remain under your control.

Updated 2026-10-04.

Open your PDF, choose a text field or checkbox, and place it where it belongs. You can then move and resize it and set its name, accessible label, required state, and appearance. The exported copy keeps the fields you created, so it can be reopened and completed in SunPDF or a PDF reader that supports AcroForm fields.

## How to use it

1. Open the PDF you want to make fillable.
2. Add and configure text fields and checkboxes.
3. Export the copy, then reopen it to check the fields.

## Available features

- Create fillable text fields
- Add interactive checkboxes
- Configure names, labels, and required states

## Limits to know

Field creation covers text fields and checkboxes. SunPDF does not create scripts, automatic calculations, submit buttons, electronic signature fields, or XFA forms.

## When to use this tool

Use this tool to turn a registration sheet, questionnaire, application, or internal document into a reusable form without rebuilding its layout.

## How to check the result

Reopen the exported PDF, enter a value in every field, select the checkboxes, and inspect field names, order, required states, and rendering in a second PDF reader.

## Local processing and privacy

Document processing happens in your browser. SunPDF does not upload your PDF to a server for editing. Closing or refreshing the tab ends the current session.

## Try the example

Fictional file created by SunPDF with no personal data.

On page 2, add a fillable text field on the Name line and an interactive checkbox beside Choice. Give them unique names, then confirm they remain fillable after export.
