Add TextField / Checkbox - Free Online Browser Tool

Add new interactive input fields or checkboxes to a PDF.

Not every PDF has the fields it should. When you have a document with printed blanks and no interactive objects, this tool adds real AcroForm text fields and checkboxes to it, so the result is a form somebody can actually complete.

This add textfield / checkbox utility runs completely inside your web browser. Your document is opened locally and processed on your own device using JavaScript and WebAssembly, so your file is never uploaded to any server. There is no signup, no watermark and no limit on how many documents you can handle.

  • 100% client-side - files never leave your device
  • Instant processing, no upload wait
  • Works on desktop, tablet and mobile
  • Free forever, no account required

    Fields are added to the document as real interactive objects. Save the newly created form.

Frequently Asked Questions

Will the fields align with the existing printed blanks?

Yes, if you drag each field to sit exactly over its blank. Adjust the size to match the printed area so the entered text looks like a normal handwritten-style entry.

Why should field names matter?

Because the name is how the value is identified in exported data and in any automation you build. Descriptive names make exports far more usable than "Text1".

Can I add checkboxes as well as text fields?

Yes, both are supported and can be mixed freely on the same page.

Do the fields show a border when the form is opened?

Field borders are a viewer setting. Some readers highlight interactive fields and others do not, so always check the result in a second reader before distributing it.

Can I add radio button groups?

Yes — Add Radio Button Choice Group handles mutually exclusive options such as Yes/No, which is the correct structure for a choice between alternatives.
