Does my file get uploaded?

No. The PDF is read and all form filling happens entirely in your browser, on your own device. The file never leaves your computer and never reaches a server — it even works offline.

Which field types does it support?

Text boxes, checkboxes, radio buttons, dropdowns, and option lists — the standard AcroForm fields that PDFs use. Signature fields are shown as read-only (use the Sign PDF tool to sign a document).

Will it show the values already in the form?

Yes. Any field that already has a value is pre-filled in the editor so you can see, keep, or change it. Read-only fields are shown but can't be edited.

What if the PDF has no form fields?

The tool tells you clearly that the PDF has no fillable form fields — it does not re-save an unchanged file or pretend something was filled when nothing was.

Fill PDF form

Open a PDF form and fill in every text box, checkbox, radio button, and dropdown — entirely in your browser. The file is never uploaded. No account, no email.
