Adobe Acrobat Reader: Sign PDFs in Adobe Reader for Free

Adobe Acrobat has a long history of PDF tools, and it brings many PDF-related features to the table. Acrobat is also an all-around PDF editor that has the full ability to handle PDF files. It’s one of the most professional PDF editors, which can be used to conduct advanced functionalities on PDFs. However, on the contrary, it’s also the professional feature that makes Acrobat not that suitable for everyone to use.

Adobe offers three PDF editors in total: Acrobat Reader DC, Acrobat DC, and Acrobat Pro DC. Only Reader DC is a free PDF viewer, and the other two versions both charge a lot. As a free PDF program, Acrobat Reader does have some limits, and it’s less professional than Acrobat DC. However, for basic editing needs, Adobe Reader is also a good choice.

Acrobat Reader enables you to sign PDF files for free easily. It also offers three methods to insert an e-signature: typing, drawing, and uploading images. If you’ve logged into an Adobe account, you can save all signatures and reuse them when operating on different devices.

With Preview, you can perform all the standard features on PDF files, including signing, encrypting, converting PDFs, and so on. More importantly, Preview has a very intuitive and responsive interface, saving you a lot of time when editing PDFs.

On macOS, it’s much easier to sign a PDF file because you can write on the trackpad with your finger directly. In addition, you can also use the camera to take a picture of your signature (written on white paper) and upload the image as an e-signature.
