Someone emails you a PDF to fill and sign. A W-9 from a client, an application from a landlord, an onboarding form from HR. The form takes three minutes. The round trip takes twenty: download it, find an app that can type on it, save a copy, open your email, find the thread, attach the right file, write a note, send. Then you notice you attached the blank one.

## The one-page version

Open the PDF in BettrPDF's Fill & Sign. If it has form fields, they are highlighted and you type straight into them. If it is a flat scan or an export, click anywhere to type. Draw your signature once and click where it goes. Then click Send it back.

Connect Gmail and it goes from your own address, into the same thread's recipient, and shows up in your Sent folder like any other email. Without a connection we send it for you, with your email on reply-to so their answer comes straight to you, and a copy to your inbox. The PDF is attached and linked.

## What the recipient gets

An email from you with the signed PDF attached and a link to a copy that stays available for 30 days. At the bottom, one plain line: Signed with BettrPDF. Nothing else.

## When you have more than one form

Applications rarely come alone. A rental application, a lease, a pet addendum and a W-9 all ask for the same name, address and dates. Autofill takes one source, like a photo of your ID or the application you already filled, and fills every matching field across all of them. You check each value, then sign and send each one.

## Is it legally binding?

A signature you draw and place yourself is a simple electronic signature under ESIGN, UETA and eIDAS, accepted for most everyday documents. See our guide on e-signature law for the exceptions.
