This Mac app lets you edit PDF files. Straightforward, yeah, but awesome.

PDFs are a double-edged sword. On one hand, even the most tech-averse can easily open and print them out without screwing anything up, making them the quintessential format for sharing documents. But if you're sharing PDFs back and forth a lot, their shortcomings become apparent pretty quickly. Because they are optimized for paper printing, modifying content requires going back to whatever program created them.

PDF Expert lets you edit text, images, hyperlinks, and more natively inside PDFs. Unlike most PDF viewers like Preview, Adobe Reader, and the one in your browser, PDF Expert can merge multiple documents into a single file to free your colleagues from email attachment hell. It's also perfect for adding inline annotations and filling out digital forms, so you can save trees without sacrificing the convenience of paper.

Additionally, PDF expert makes it easy to extract embedded media from documents, so you don't need to rely on awkward screenshots to save images and logo files. You can get PDF Expert 2.0 for Mac for 50% off the usual price—just $29.99.
