However, it becomes hard to choose the best of anything when there are too many choices, and that is why we’ve decided to list the best tools that you can use to open JAR files.

The entries were chosen based on multiple criteria, including effectiveness, price, how easy it is to use, system requirements, all so that you can make a more informed decision before choosing one or another.


Which are the best tools to open JAR files?

It has pretty fast work speeds, allowing it to compress and decompress large amounts of data in very short periods of time, without using too many system resources, as you can test for yourself from the Task Manager.

7-Zip

If you’re dealing with JAR files, chances are that you’re into coding as well, and if you do, then the best archiving tool that you can use to open JAR files is most likely 7-Zip.

This tool has been around for some time, and while it does come with a traditional UI for beginners, the fine aspects of archiving can be tweaked via detailed commands that you can input in its console.

As far as opening JAR files goes, it can be used to efficiently access its contents, and the only real reason it is last on our list is because the tool ‘s UI-based version isn’t very modern-looking, and may deter certain users.
