Fill PDF Form
Fill empty fields on a fillable PDF, then download it. If the file has no fields, type on the page instead.
Click empty fields
If the PDF already has form widgets, you type straight into those blanks.
Format as you type
The format toolbar appears next to the field you are filling so you can change size, color, and font.
Keep or flatten
Download keeps the fields editable. Flatten bakes the answers into the page.
How to fill a PDF form
Upload a PDF. Fillable files show empty fields you can click.
Click a blank on the page and type. Use the toolbar next to the field to change size, color, or font.
Download a still-fillable copy, or flatten so the answers cannot be edited.
Fill a PDF form without printing it
What this tool fills
Use Fill PDF when the file already has interactive fields — the empty boxes you can click in Adobe Reader. Type into those fields, tick checkboxes, and pick dropdowns, then download.
If there are no fields
Many PDFs only look like forms. They are scans or Word exports with lines, not real fields. This tool tells you that and lets you type on the page. It does not invent fields from a photo.
Fillable vs flattened
Download keeps the form editable. Flatten writes the answers into the page so they display the same in every viewer and cannot be changed later.
