What is JAR?
Archive/Compression file formats
Sun Microsystems, now Oracle Corporation
JAR, or Java Archives, are executable Java programs by the Java Runtime Environment (JRE).
Please note that MConverter cannot create an executable program if the provided source archive file was not a compiled program for the same platform. When converting from JAR to another format, MConverter only extracts the contents of the JAR file. It does not make it installable in another format.
Common questions about JAR conversions
How to open a JAR file?
If you don't know how to view a JAR file, you can convert it to another format you already recognize. You can use MConverter for the conversion.
Can I convert JAR files in bulk?
Yes, MConverter supports batch converting of multiple JAR files at once. You can even drag and drop folders containing JARs. Pasting JAR files and folders copied in the clipboard also works: use Ctrl+V.
Can I convert a JAR file, if its size is 1 GB?
Yes, with MConverter Premium you can convert big JARs, up to 1 gigabyte each. The free version lets you convert files up to 200 MB. If you need to convert JAR files over 200 megabytes, try MConverter Premium.
Is converting JARs safe with MConverter?
Yes, we encrypt your connection using industry standards. Plus, your JAR files are only accessible by you. 24 hours after the conversion completes, they are automatically deleted from MConverter’s servers. You can also delete your JARs and other converted files immediately after finishing the conversion by clicking the bin icon. Join others who have trusted us to convert over 2,645,597 files so far.
How long does it take to convert JAR?
For most archive files, the wait is often less than a minute. However, MConverter also supports converting larger archive files, meaning that it could take a while (up to over an hour, for example).
