Bottom LineĪdobe Reader proves to be the most functional, free PDF reader and editor available.
Two of these advanced features are emailing files directly from the application, and converting PDF files to other formats, including to Word. Instead, if you want to take advantage of some of the more advanced features, you must sign up for a monthly subscription that starts at $1.99 a month. Some advanced features require subscription: Adobe Reader doesn't have a paid version. We have not experienced any technical glitches. Reliable: It opens and displays files of all sizes, even large ones with many detailed images, quickly and smoothly. Streamlined interface: Although the amount of features is impressive for a free application, the interface is clearly laid out and easy to navigate. You can choose to either type your signature, import a picture of your signature, or draw it using a mouse or trackpad. This is an especially useful feature when you need to fill in and return a form or sign a document, but you don't have a working printer close by. Supports signatures: With this app you can add your signature onto files. This is especially helpful since nowadays many forms that you download from the Internet require you to use it to fill in the blanks.
It also lets you submit forms created with fillable form fields. Good functionality: With Adobe Reader for Mac, you can do more than just view PDF files - you can edit them as well, adding text and placing check marks and initials. Adobe Reader for Mac is an essential application for reading, printing, marking up, and commenting on PDF files.
