My MacOS X

One of the great features in Adobe Acrobat Pro is the ability to annotate (comment, markup, circle, highlight) PDF documents and images like JPEGs, PNGs, etc. Although, there are many other features (like creating forms) in Acrobat that are useful for PDFs, it’s not really fair to compare it to Preview. Nonetheless, for those who don’t have Acrobat Pro or don’t want to buy it, Preview has become quite powerful especially with the new Annotate toolbar added in Snow Leopard.

1. Open up a PDF or IMAGE on your Mac with Preview.
2. Click on the Annotate button in Preview, located next to the Select button on the top.
3. Now, you should notice a toolbar appear on the bottom on Preview.
4. Use this Annotation toolbar to highlight text, add circles or squares around important text, add hyperlinks, add text, or add colorful arrows.
5. Once you’re done making any changes to the file, make sure to save it.
