Fill PDF Form — AcroForm Fields, In Browser
Drop a PDF with AcroForm fields and the tool extracts them into a regular HTML form below. Fill in values, choose options, then download the filled PDF. Optional flatten step bakes the values into the page so recipients can't edit them.

When to use this tool
Quickly fill an AcroForm — claim forms, applications, school enrolment — without firing up a desktop PDF editor. After filling, choose "flatten" if you want the recipient to see your answers as permanent text instead of editable fields.
Step by step
- Drop one PDF. Forms with AcroForm fields are detected; XFA forms aren't supported.
- Fill the fields in the panel below. Text, checkboxes, radio buttons, and dropdowns are all supported.
- Optionally flatten. Flattening makes the values part of the page — readers can't change them.
- Click "Fill & download". Output is
name-filled.pdf.
FAQ
What's the difference between AcroForm and XFA?
AcroForm is the standard, supported format. XFA is a legacy Adobe format used by some government forms — it's not supported here. Look for the Highlight Fields button in Acrobat: if it works, the form is AcroForm-compatible.
Are my files uploaded?
Never — extraction and filling happen entirely in your browser via pdf-lib. See the privacy policy.
No fields appeared — why?
Either the PDF has no AcroForm fields (it's just images of input boxes), or it uses XFA. For image-only forms, use Sign PDF to stamp values, or print, sign, scan.
