A BMP to JPG conversion is often performed to get files in smaller size or speed up the file uploading. To solve this problem, we here list several methods to batch convert BMP to JPG, even convert JPG to BMP easily.
BMP format, also known as bitmap image file format, is used to store bitmap digital images.
BMP is really an old file format which works as the default file format on Windows and OS/2 operating system. It can store two-dimensional digital images in various color depths. Though it is lossless technically, it doesn’t have any compression, and this is also the reason why BMP files are quite large, even huge in size.
Hence, we need to convert the BMP files into smaller JPG. Since this is about the conversion on image files, generally speaking, if we can convert BMP to JPG, we can also convert JPG to BMP via the same method.

So, no matter you want to convert BMP to JPG, or JPG to BMP, PNG to JPG, JPG to PNG, Tiff to JPG, JPG or Tiff, etc. you can kill all these all problems with only one tool.
