How to fill a PDF form online for free
You were sent a PDF to "print, fill and scan back." You do not have a printer handy, the form looks cramped, and you would rather not waste paper on something that will be filled in five minutes. This guide shows the fastest way to fill any PDF form on screen — free, private, and without creating an account.
Why filling on screen beats print-and-scan
Print-and-scan is the workflow almost everyone dreads: find a printer, print a form you will immediately mark up, write by hand, scan it back, and hope the result is legible. Every step adds friction and a chance for error. Filling the PDF directly on your computer or phone removes all of it — the text is crisp, you can fix a typo instantly, and there is no paper involved.
The catch is that most free tools either upload your document to a server, stamp a watermark across it, or push you to a subscription right before you download. Formagator was built to avoid all three: filling and field detection happen entirely in your browser, there is no watermark, and your first form needs no account.
Step by step
- Open FormagatorThere is nothing to install. The editor runs in your browser on desktop or mobile.
- Upload your PDFDrag the file onto the page or click to choose it. The file never leaves your device — it is read locally.
- Type into the fieldsFormagator detects where the answers go — lines, boxes, and cells — and places input fields there. Click a field and type. Font and size are matched to the form so your text blends in.
- Add signatures and checkmarksNeed to sign or tick a box? Draw your signature with a mouse or finger and drop checkmarks where they belong.
- Download the finished fileExport a flattened PDF that looks exactly the way it should when the recipient opens it — no editable fields left behind, no watermark.

Free, no sign-up for your first form, nothing to install. Your file stays in your browser.
What if the PDF is a scan or photo?
Many "forms" are really scans or phone photos with no interactive fields at all. Formagator reads the layout of the page — including faint printed lines and grids — and, for image-only pages, uses on-device text recognition to understand where the labels and answer spaces are. That means you can fill a photographed form the same way you fill a clean digital one. If you want the details, see our guide on filling a scanned PDF.
Is it really free?
Yes. Filling a PDF and downloading it is free, with no watermark and no account required for your first form. An optional free account only exists so that your saved drafts, signature and profile follow you across devices — it is a convenience, not a paywall.
Frequently asked questions
Do I need to download software?
No. Formagator is a website. It works in Chrome, Safari, Edge and Firefox on any operating system.
Will there be a watermark on my form?
No. The exported PDF is clean. Adding watermarks to free exports is exactly the practice Formagator was built to avoid.
Can I fill the form in another language?
Yes — any language, including right-to-left scripts like Hebrew and Arabic. See this guide.
Is my document uploaded to a server?
No. Field detection and filling happen in your browser. A document is only stored if you sign in and explicitly choose to save it.
