# About FairFill PDF

FairFill PDF is a PDF editor that runs in your web browser. You open a PDF, fill it in, sign it and download it, and the PDF never leaves your device.

## Who it is for

It is built for the person who needs to fill in or sign a PDF now and then: a W-9 for a new client, a lease, a school form. For that, we think one flat price beats a monthly subscription.

## What it costs

Merging PDFs and reordering, turning and removing pages is free. Filling in, signing, typing on a page, making a PDF fillable and blacking out text cost $1.99, paid once when you download. That one payment covers every download for 24 hours. Nothing renews, and there is no account to cancel. [Pricing in full](https://fairfillpdf.com/pricing/).

## How it works

The editor is a web page. It opens your PDF, shows it and builds the finished copy inside your browser tab, on your computer or phone. Your PDF is never sent to us. The only thing our server handles is your payment, and the card itself is entered on Stripe's page. [How we handle your data](https://fairfillpdf.com/privacy/).

## How it makes money

From the $1.99 payments and nothing else. The site carries no advertising, and we never receive your documents.

## What it does not do

It can't open a PDF that has a password or an edit lock, change the words already printed in a PDF, make a PDF smaller, or open Word files. A signature made here is a picture placed on the page: there is no identity check, audit trail or tamper seal.

## Official forms

The W-9, W-4 and I-9 that open with one button are the agencies' own PDFs. FairFill PDF is an independent product. It is not part of the IRS, USCIS or any government agency, and the agencies don't endorse it. [Forms you can start from](https://fairfillpdf.com/forms/).
