The app has a series of powerful annotation tools such as the Sticky Note, Measuring tools, and Shapes, as well as classic editing capabilities such as underline, highlight, and strike through. You can modify text and objects (edit existing text, insert images, move and select objects, change their sizes, etc.), as well as annotate PDF documents. FeaturesĪs mentioned before, Master PDF Editor is designed to be a one-stop-shop PDF app for everyone willing to pay a premium. Other than that, the app is quite nice with a snappy (albeit very busy GUI), and enough customization options to keep everyone happy. The first thing that stands out when opening Master PDF Editor is its Windows-inspired looks, with the classic menu bar at the top, and a hefty toolbar underneath it.

In fact, Master PDF Editor is a paid app (the demo version doesn't have any limitations except adding a watermark on the output file). It's not your typical open-source app a day-to-day Linux user might come to expect, but it gets the job done nicely. Master PDF Editor is a comprehensive PDF suite that allows you to create, edit, view, encrypt, sign, or print interactive PDF documents on Linux, Windows, and macOS.
