  3. Fill the text fields, tick the checkboxes and choose your options.

Why use Fill PDF Forms?

The alternative is printing the form, writing on it, scanning it back in and emailing a crooked grey photograph of it. Filling the fields directly keeps the text legible and the file small. Application forms and tax paperwork are exactly the documents you least want passing through someone else's server, and here they do not.

Privacy and browser processing

Your files are processed in your browser. Nothing is uploaded to a server, so your document never leaves your device.

There is no account to create and nothing to install. Because the work happens on your device, the speed depends on your device rather than on how busy a server is — and closing the tab is all it takes to remove every trace of the file from this page.

Limitations

Worth knowing before you start:

  • The form needs real PDF form fields. A scanned or flat form has nothing to fill — use Edit PDF to add text on top instead.
  • XFA forms, used by some government and banking PDFs, are not supported.
  • Digital signature fields cannot be signed here.
  • Password-protected PDFs must be unlocked before their fields can be filled.

Frequently asked questions

Is filling a PDF form free?
Yes. Filling and downloading is free, needs no account and adds no watermark to the completed form.
Are my form answers uploaded to a server?
No. Everything you type stays in your browser and is written into the PDF on your own device. Nothing you enter is transmitted or stored.
What if no form fields are detected?
The document is probably a scan or a flat PDF with no interactive fields in it. You will get a clear message saying so, and you can use Edit PDF to place text wherever it needs to go.
What does flattening do?
Flattening turns your answers into permanent page content, so the recipient sees fixed text rather than editable boxes. Leave it off if you want the form to stay editable later.
Can I sign the form here?
You can add a visible signature using the Edit PDF tool. Certificate-based digital signature fields are not supported.
Does this work on a phone?
Yes. Fields are listed in a form you can work through in order, so you are not pinching and zooming to hit a small box on the page.
