A Quick Note About Adobe:
While the signature tool in Adobe Acrobat Reader is totally free, there is a catch. Many of Adobe’s other helpful features are not free. If you want to change the text in a document, delete a page, or merge two files, Adobe will ask you to pay for a monthly subscription.
If you need to make other changes to the file, you can use a free PDF editor like JOPDF, which lets you handle those extra tasks without costing a penny.

If you use an Apple Mac computer, you are in luck. You do not even need to download a new program to sign your contract. Mac computers come with a built-in program called Preview. This program opens photos and PDFs automatically.
Many people do not know that you can actually edit a PDF in Preview. It has a special hidden menu just for making changes and adding signatures.
Here is how to do it on a Mac:
Step 1. Double-click the file. Unless you have changed your computer settings, it will automatically open in the Preview program.
Step 2. Look at the top right of the Preview window. Find a small icon that looks like the tip of a marker or a pen inside a circle. Click this Show Markup Toolbar to show more tools.
Step 3. Next, look for the Signature tool and click Create Signature.

Step 4. You can select Trackpad and use your finger to write your name. Or, you can use the Camera option. Align a piece of paper with your signature towards the computer camera. The computer will scan it and convert it into a signature.
Step 5. Click Done when you are finished creating the signature. Then select the signature and place it in the correct position.
