Good to know

  • Works with standard PDF forms (AcroForm): text boxes, checkboxes, radio buttons, dropdowns and lists.
  • Dynamic XFA forms made with Adobe LiveCycle can only be filled in Adobe Acrobat or Reader. We tell you if your file is one.
  • Flattening turns the answers into ordinary page content. Nobody can change them afterwards, including you, so keep the unflattened copy if you might need to edit.
  • Read-only fields are shown but left as they are.
  • Any existing digital signatures are no longer valid after filling.
  • This tool runs in your browser. Very large files depend on your device's memory.

Guides

Fill PDF forms: common questions

Is Fill PDF forms free?
Yes. Fill PDF forms is free and works without an account, for files up to 25 MB and 150 pages. A free account raises that to 50 MB and 400 pages.
Are my files uploaded to a server?
No. Fill PDF forms runs in your web browser, so the file is read on your own device and never sent to ConvertFile.
Why does it say my PDF has no fillable fields?
The PDF only looks like a form: the boxes are printed lines, not real fields. You can still put text or a signature on it with Sign PDF or Add watermark. If we say it's an XFA form, it needs Adobe Acrobat or Reader.
What does flattening a form do?
It turns your answers into ordinary page content and removes the fields, so the form can't be changed afterwards. Some offices ask for flattened forms. Keep an unflattened copy if you may need to edit it.
Does Fill PDF forms work on Mac, Windows, Android and iPhone?
Yes. It runs in any modern web browser, with nothing to install. Very large files work best on a desktop or laptop, because in-browser tools use your device's memory.
