About DocFills

DocFills is a free online PDF toolkit built to eliminate the friction of filling forms, signing documents, and editing PDFs. We believe everyone should be able to complete official paperwork in minutes — without expensive software, confusing interfaces, or unnecessary accounts.

AI that actually helps

Our AI PDF filler detects fields on any document — including scanned and non-fillable PDFs — and maps your answers to the right labels. Pick an official template like W-9, I-9, or DS-11, answer a few questions, and download a completed PDF in seconds.

Privacy by design

PDF editing and signing run entirely in your browser. For AI filling, documents are processed on secure servers and deleted immediately after download. We never sell your data. Read our Privacy Policy for details.

Who uses DocFills?

DocFills is built for freelancers completing tax forms, HR teams onboarding employees, travelers applying for passports, small businesses sending W-9s and 1099s, and anyone who needs to sign or edit a PDF without paying for desktop software. Whether you upload your own document or start from a pre-built template, the workflow stays fast and free.

We publish free step-by-step guides and maintain a growing library of official form templates so you can find answers quickly — in search engines and AI assistants alike.
