Search, inspect, merge, and annotate PDFs directly in your browser. Form filling and preview are free with an account; the first clean form download has no watermark.
Most PDFs that arrive in your inbox are flat: the page is there, but nothing on it is clickable. These pages cover getting your answers onto a document like that — whether it came from a scanner, a phone camera, a Word export, or a government website. The starting point is the same in every case (upload the file, put fields where the answers go, type, download); the pages differ in what you are trying to end up with.
Add fields to a flat, scanned or exported PDF so it can be typed into. Draw them yourself, or let AI place them.

Open toolThe PDF won't let you click anywhere. This is the most common case, and it is not a broken file — it simply has no form fields in it. A scan, a photo of a printed page, and a PDF exported from Word all behave this way. You do not need to rebuild the document to fix it. Open make a PDF fillable, put a box wherever an answer belongs, and type into it. The page underneath is never modified.
Someone else has to fill it in. Then the fields have to survive being emailed. Exporting an interactive AcroForm gives the recipient a file with real clickable fields that works in any PDF viewer, with no account on their side — converting a PDF to a fillable form covers that. A flattened download is the opposite choice: the values are baked into the page and can no longer be edited, which is what you want once the answers are final.
It's a form the government publishes. Check the form library first. Over 120 of the most-filed forms — W-9, I-9, 1040, 2848, N-400, DS-82 and the rest — have a page with a plain-language walkthrough, a line-by-line field breakdown, the mistakes that get filings rejected, and a one-click button that opens the official blank straight in the editor, so you never have to hunt the PDF down yourself.
You just need something done to the file. Merging, splitting, highlighting, searching the text, or checking who created it are all handled by the utilities above. They run locally in your browser, need no account, and are unlimited.
Search, inspect, merge, split, and basic annotation stay in your browser. The form filler uploads your document for server-backed filling, persistence, or AI processing.
Local utility tools avoid server queues. Form filling supports PDFs up to 50 MB and may take longer when AI processing is requested.
No software to install. Works on any device with a modern browser — Windows, Mac, Linux, tablet, or phone.
JustFill goes beyond basic tools. Upload any PDF — scanned, flat, or AcroForm — and fill it instantly with AI-powered field detection.
