With support for 3-way compare, folder sync, Excel file compare, and a lot more.
UltraCompare v16 gives you the ability to rapidly compare 2 or 3 files from multiple locations at once, and merge conflicts and differences visually.
Whether you prefer a darker look, or a more classic white-based skin, UltraCompare's interface is completely themeable, and comes with several themes hand crafted at IDM. If you design a theme you'd like to share with the rest of our users, send us a pull request on GitHub, or simply email it to our support team.
Compare over FTP
UltraCompare's powerful compare functions work just as well over FTP, and even network shares and connected drives. Simply click to open from FTP, choose your connection or create a new one to save for future use. It's perfect for quickly checking local files and folders against what's already on the server.
UltraCompare's special document handling makes it easy to compare Word and PDF files. Just open them in your session as you would any other file, and let us take care of the rest.
Sometimes you simply want to quickly compare the contents of a file archive without extracting it for a normal file or folder compare. We've got you covered. With UltraCompare, you can easily open and compare .zip, .rar and .jar files. No setup required.
Compare large files
UltraCompare is built to compare the large files that cause other comparison tools to crash. People who deal with databases and large log files absolutely love our products for this very reason.
4k UHD support
UltraCompare looks great on Retina and other ultra high-definition displays. If you haven't upgraded yet, no need to worry. We'll be ready for you when you do.
UltraCompare is available for Windows, Mac and Linux. Even if you've got one of those distros nobody's heard of, there's a good chance we may be able to help you.
