You're sent a PDF form, you click a box to type — and nothing happens. Most forms are “flat”: a scanned or printed page with no interactive fields, so the usual advice is to print, fill by hand and scan back. You don't have to. You can fill out any PDF form for free by typing straight onto the page in your browser — no printer, no upload, no watermark.
Why some PDFs won't let you type
A truly “fillable” PDF has form fields built in by whoever made it. Most everyday forms — government paperwork, school slips, scanned applications — are just flat images of a page, with no fields to click. Rather than fighting that, the fill tool lets you drop text boxes anywhere on the page, so it doesn't matter whether real fields exist.
Step-by-step
- Open the Fill PDF tool.
- Drop in the form.
- Click anywhere on the page and type — add a text box per field.
- Add checkmarks or dates where needed and line everything up.
- Download the completed form.
Everything happens locally, so a form full of personal details never leaves your device.
Signing as well as filling
Many forms need a signature at the end. The fill tool lets you sign as you go, or you can finish filling and then add a signature with the dedicated Sign PDF tool — draw, type or upload your signature and drop it on the line. Between them, filling and signing a form end-to-end never requires printing anything.
Tips for clean, professional forms
- Match the text size to the printed labels so it looks native.
- Align to the lines — nudge boxes so text sits on the field, not floating above it.
- Zoom in for tight boxes to place text precisely.
- Need to rearrange pages? Combine or reorder with the PDF merger before or after filling.
