How to Add a Signature in Adobe: Step-by-Step Guide

Introduction:

If you are wondering how to add a signature in Adobe, you are definitely in the right place. This guide will walk you through the exact steps. Plus, we will show you an amazing free PDF editor that makes the job even easier.

Can You Add a Signature in Adobe for Free?

The answer is yes! You can absolutely sign a PDF in Adobe Reader without spending a single penny. Adobe offers a free basic tool that lets you quickly add your personal signature to your documents.

However, there is a big catch. While putting a simple signature on a page is free, Adobe heavily restricts its more useful features. If you need to fix a spelling mistake in your text, change an image, combine two files together, or password-protect a PDF, Adobe will stop you. The program will prompt you to upgrade and buy one of their very expensive premium subscriptions.

It can be very frustrating to use software that constantly asks you for money just to do simple tasks. But do not worry! If you want a comprehensive tool without any hidden fees, there is a perfect Adobe Acrobat alternative. Later in this guide, we will introduce you to JOPDF. It is a 100% free PDF editor that gives you full control over your files.

How to Add a Signature in Adobe

Let’s learn how add signature in Adobe Acrobat. There are two main ways to sign your document in Adobe, depending on what kind of security you need.

Method 1. Use the Fill & Sign Tool for an Electronic Signature

This is the most common and easiest way to sign a document. It is used for everyday tasks, like signing a standard business contract, a permission slip, or a simple form.

Step 1: Open your PDF document. Find the file on your computer and double-click it to open it in Adobe Acrobat Reader.

Step 2: Look on the right or left side of the screen and click the Fill & Sign button.

Step 3: Then, click the Add signature option to continue.

Step 4: A new pop-up box will appear, and you have three easy choices here.

  • Type – Just type your name on your keyboard, and the computer will change the font to look like fancy handwriting.
  • Draw – You can use your computer mouse, your laptop trackpad, or a digital pen to draw your actual signature.
  • Image – If you have a picture of your real signature saved on your computer, you can upload it here.

Step 5: Once you like how your signature looks, click the Apply button. Now, your mouse pointer will carry your signature around the screen. Just click anywhere on the page to drop your signature into place.

If needed, you can drag the corners to make it bigger or smaller, and then save your file.

Method 2. Use a Certificate for a Digital Signature

How to sign a PDF with Adobe more securely? You can add a digital signature. It will lock the document so that nobody can secretly change the text after you sign it. When you need to sign contracts, bills, and other business-related documents, you can use this method.

Step 1: First, open your PDF file in Adobe.

Step 2: Go to the tools menu and click on the Use a certificate button.
