MConvert

MConvert is a free and open-source Java-based application you can use to convert files between different formats, such as BMP to JPG, AIFF to AU, or WAV to AIFF.

It contains just a couple of settings that can be easily configured, even by those with little experience in file conversion software.

As long as you have the Java Runtime Environment installed on your computer, you don't need to set up anything else. This means that you can copy the downloaded files to a custom directory on the disk or to a removable storage unit, in order to seamlessly launch MConvert on any PC with Java. It doesn't add new entries to the system registry or create files on the HDD without your permission.

The GUI is user-friendly, represented by a standard window with a non-sophisticated appearance and neatly structured layout, where you can get started by picking the conversion mode between BMP to JPG (PixConverter), JPG to BMP (PixConverter), AIFF to AU (Sox), AIFF to WAV (Sox), AU to AIFF (Sox), AU to WAV (Sox), WAV to AU (Sox), and WAV to AIFF (Sox).

In the following step, you can resort to the file browser to locate the source file as well as specify the directory and name of the new file you want to create.

The conversion operation is performed rapidly, after which you can open the new files to inspect results. The utility gives you the possibility to set a new image width and height for the output files. There are no other noteworthy settings provided by this tool.

It didn't put a strain on the computer's performance in our tests, thanks to the fact that it consumed a low amount of CPU and RAM during its runtime. It carried out tasks fast.

However, we've noticed that it has some compatibility issues with newer Java versions, refusing to launch. On top of that, it doesn't support batch processing, so you can convert only one file at a time. We are also keeping in mind that MConvert hasn't been updated for a long time.
