Format description
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.

Can I convert a file to JAR, if its size is 10 GB?
Yes, with MConverter Max you can convert big files, up to 10 gigabytes each.
The free version lets you convert files up to 100 MB. If you need to convert files over 100 megabytes to JAR, try MConverter Max. If your files aren’t over 1 GB, then you can use MConverter Plus instead, as it’s cheaper.

Is converting to JAR safe with MConverter?
For cloud-based conversions, MConverter encrypts your files using the latest technologies, such as TLS 1.3 and HSTS. They are transmitted securely to our cloud service provider’s EU-based data center, which holds internationally recognized ISO 27001 and SOC 2 certifications. There, each conversion is processed in a separate, isolated environment. This technique further reduces the risk of a malicious file impacting other conversions.
Four hours after the conversion is complete, your files are automatically deleted from MConverter’s systems. You can also permanently delete your files immediately after finishing the conversion with the trash icon.
When converting on-device, your files never leave your device. MConverter processes them locally. Note: on-device conversions are not yet available for some hardware-intensive formats.
For both cloud and on-device conversions, your files are never scanned or shared with third parties for marketing purposes.
