Fill PDF

Type into a PDF form's fields — text boxes, checkboxes, dropdowns — then keep it editable or lock it flat. Free, private, entirely in your browser.

Quick Answer

Filling works on any PDF with interactive AcroForm fields — the boxes you can click into in a desktop PDF reader. If a PDF has no form layer (just blank lines or a scanned image), the field list stays empty; use Edit PDF Text or OCR instead.

Key Facts

  • Every field type the form layer exposes: text boxes, checkboxes, and dropdowns
  • Values are typed into a labeled list — no pixel-hunting for tiny boxes on the page
  • Keep the form interactive for later edits, or flatten to lock answers in permanently
  • Runs entirely in your browser: the file and your answers never touch a server

Frequently Asked Questions

How do I fill in a PDF form for free?

Upload the PDF here. If it has interactive form fields, every field appears in a list with its name and a box to type into — fill what you need and download. No account, no watermark, no upload to a server.

Why does the field list come up empty for my PDF?

The PDF has no form layer. Many "forms" distributed as PDFs are just flat text with drawn lines — those need text editing rather than form filling. Scanned forms need OCR first.

What's the difference between keeping the form interactive and flattening?

Interactive keeps the field boxes live so you (or anyone) can reopen and change the answers later. Flattening converts your answers into permanent page content — ideal before sending a tax form or application where edits should be impossible.

Are checkbox and dropdown fields supported?

Yes. Checkboxes appear as toggles in the list, and dropdowns show every option the form defines so you can pick one.
