How to Sign a Document Online

Signing a document online replaces the print-sign-scan-email cycle with a few clicks in your browser. Whether you are the person requesting a signature or the person being asked to sign, the process is fast, works on any device, and produces a verifiable record.

This guide walks through both sides: how a recipient signs a document they have been sent, and how a business sends a document out for signature.

If you were sent a document to sign

You do not need an account, an app, or a download. You will receive an email with a secure link that is unique to you.

• •Open the email and click the secure signing link.
• •Review the document. You can scroll through every page before signing.
• •Agree to use electronic records and signatures when prompted (this consent is part of what makes the signature valid under U.S. law).
• •Click each signature, initial, date, or text field and complete it. You can draw your signature, type it, or upload an image.
• •Submit. You will be able to download a completed copy for your records.

If you want to send a document for signature

• •Upload the PDF you need signed.
• •Drag signature, initial, date, name, and text fields onto the page and assign each to a recipient.
• •Add your recipients and, if needed, set a signing order so people sign in sequence.
• •Send. Each recipient gets their own secure, expiring link.
• •Track progress in real time — you will see when each person views and signs, and get the finalized PDF with a completion certificate when everyone is done.

What makes an online signature trustworthy

A trustworthy e-signature platform records who signed, when, and from where, and protects the finished document against tampering. Tarchos Sign captures a timestamp, IP address, and device for each action, appends a completion certificate, and stores a content hash so any later change to the file can be detected.
