About this app

FormFill turns any PDF or paper form into something you can fill out, sign, and send — right from your phone. No subscription, no account, no cloud. Everything happens on your device.

FILL AND SIGN, OFFLINE
FormFill is a fill and sign app and esign app in one: open a PDF form, fill it in, esign documents with your own signature and share a flattened PDF. It all works offline, with no account.

Filling out a form shouldn't mean a bloated app or a monthly subscription. FormFill keeps it simple — and completely private.

FILL ANY FORM
• Scan a paper form with your camera, or import a PDF or photo
• Tap anywhere to add text — your name, address, dates, anything
• Add checkmarks and X marks to boxes
• Drop today's date in a single tap

SIGN IN SECONDS
• Draw your signature once, then reuse it on any form
• Add your initials the same way
• Place, resize, and position your signature exactly where it belongs

SEND IT
• Flatten your filled form into a clean, finished PDF
• Share it, email it, or save it to your files
• Your completed documents stay in your on-device library

COMMON FORMS, READY TO FILL
• Fill out a W-9, W-4, I-9, 1099-NEC or SS-5 on your phone from the official IRS, USCIS or SSA PDF
• State DMV bill of sale forms (California, Florida, New York, Washington) from the agency's own file
• Common forms in Settings opens our library: each form explained field by field, with the steps in FormFill
• Works on any government form, fillable or not — FormFill writes on top of the page

FILL OUT PDF FORMS ON YOUR PHONE
Fill out a PDF on your phone without printing it: open the file, tap a field, type, and sign. FormFill works on tax forms, leases, rental applications, contracts, medical intake forms, school permission slips and bills of sale, whether or not the PDF has fillable fields. If it is a flat scan, FormFill writes on top of the page.

A SIGN PDF APP WITHOUT THE SUBSCRIPTION
Sign a PDF and email it in a minute: draw your signature once, place it, flatten the form and share. Add a signature to a PDF document, add your initials, and keep a clean copy in your library. The basics have no monthly fee, and Lifetime is a single payment.

WHAT PEOPLE USE IT FOR
• Sign a lease or rental application from the couch
• Fill out a W-9 for a new client or a W-4 for a new job
• Complete and sign a contract, permission slip or consent form
• Fill in a printed form: scan it, type on it, send it back
• Sign documents on your phone when there is no printer, no scanner and no signal
• Esign a form for work, school, a landlord or the DMV, then keep a copy on your phone
• Fill out a PDF without uploading it to anyone's cloud
• Add text, checkmarks and today's date to any form in seconds

PRIVATE BY DESIGN
• 100% on-device — your documents never leave your phone
• No account, no sign-up, no cloud server
• Nothing to leak, nothing to track

HONEST PRICING
FormFill is free to fill and sign your first documents. Go Pro to unlock unlimited documents, saved signatures and initials, and a reusable autofill profile for one-tap form filling. Choose a one-time Lifetime purchase — pay once, own it forever — or an annual plan that starts with a free trial. No surprise fees, and you can cancel anytime.

A genuinely simple PDF form filler and signer for anyone who just needs to scan a document to a fillable PDF, sign it, and get on with their day.
