But, what if the file you need converted isn't one of these types of files? There are many formats that are not video, audio, image, or document based.

Here are several freeware file converters for several less common formats like disc images, fonts, compressed files, and more:

Most of these programs convert only certain types of files, so look through them all for one that supports the file type you need to convert.

ImgBurn: Disc Image Converter

ImgBurn program

ImgBurn is a free disc image converter program that supports the majority of common disc image formats.

Input Formats: APE, BIN, CCD, CDI, CDR, CUE, DI, DVD, FLAC, GCM, GI, IBQ, IMG, ISO, LST, MDS, NRG, PDI, TAK, UDI, and WV

Output Formats: BIN, IMG, ISO, and MINISO

Actually, ImgBurn is an advanced, full-featured CD/DVD/BD disc burning and image management tool but it works great at converting between most popular disc image file types.

To convert between disc file formats, choose Create image file from files/folders on the main screen. In the Source area, browse for the file you want to convert, and then in the Destination section, choose where to save the exported file to get a list of the output formats to pick from.

ImgBurn can be used on Windows 10 down through Windows 95, including Windows Server 2008 and 2003. ImgBurn also runs on Linux.

ImgBurn may try to install another program or two during setup that you don't need. You can easily skip over them if you wish.

Zamzar: Compressed File Converter

Zamzar website

Zamzar is an online file converter service that supports several popular archive and compressed file formats.

Input Formats: 7Z, TAR.BZ2, CAB, LZH, RAR, TAR, TAR.GZH, YZ1, and ZIP

Output Formats: 7Z, TAR.BZ2, CAB, LZH, TAR, TAR.GZH, YZ1, and ZIP

Zamzar is also a very good image converter and document converter.

The 150 MB source file limit at Zamzar makes it ideal to use the service for bigger compressed files. However, Zamzar's conversion time is sometimes slower than other online file converters we've tested.

FileZigZag: Compressed File Converter

FileZigZag ZIP to 7Z conversion

FileZigZag is another online file converter service that will convert several compressed and archive file formats.

Input Formats: 7Z, 7ZIP, AR, ARJ, BZ2, BZIP2, CAB, CPIO, DEB, DMG, GZ, GZIP, HFS, ISO, LHA, LZH, LZMA, RAR, RPM, SWM, TAR, TAZ, TBZ, TBZ2, TGZ, WIM, XAR, XZ, Z, and ZIP

Output Formats: 7Z, 7ZIP, BZ2, BZIP2, GZ, GZIP, RAR, TAR, TAZ, TBZ, TBZ2, TGZ, and ZIP

FileZigZag sometimes seems to take some time to convert files, especially those that are large, but it's usually still faster than other online conversion tools. However, it does function well as a document converter and an image converter because those types of files are usually much smaller than archive files.
