Fill PDF forms

Fill existing PDF form fields and export a flattened copy.

About Fill PDF forms

Fill PDF Forms finds the interactive fields in a document, lets you type into them, and can flatten your answers into the page appearance.

Runs entirely in your browser. Your files never leave your device.

1.Open the PDF and check the text fields, checkboxes, dropdowns, and buttons are all detected.
2.Fill it in, watching field formats, required markers, character limits, and any field that calculates from another.
3.Read every page, export editable or flattened, then reopen it and confirm the values are there.

An editable export keeps the fields, so you can come back and change an answer.
Flattening turns the answers into page content, which looks the same in every viewer.

XFA forms, scripted calculations, signature fields, and custom widgets may not be supported.
Flattened answers are hard to change. Do it once you have checked them.

Should I flatten a finished form?

Flatten when the recipient only needs the values and it has to look identical everywhere. Keep an editable copy for yourself.

Why is one field missing?

It may be XFA, script-driven, or a custom widget. Some documents also just draw a box that looks like a field, with no form object behind it.
