ZamZar is also easy to use, but you have to give them your email address and they will then email you the file. Easy2Convert has a small freeware program that was written specifically for this type of conversion. The freeware version lets you choose one BMP file, the output folder and adjust the image quality.
The freeware program also has built-in command line support, so if you are familiar with using the command line, you can create a batch script to batch convert many files at once.
The second useful feature is the ability to scan a folder and all of its subfolders for BMP files. Related wikiHows How to. How to. About This Article.

It uses the technology of encoding smooth color renditions, providing the ability to reduce the amount of data frequently during the image recording. Because of the small size, it is requested by the owners of websites, allowing you to save the traffic effectively. It is also frequently used in memory cards of digital video cameras. The JPEG algorithm is optimally suitable for compressing photographs and pictures in which realistic scenes with little contrast of colors are present.
It is not recommended to use this format to compress drawings and various graphics since a big difference between several near located pixels provokes visible artifacts. The procedure for compressing the digital images in JPEG format is carried out in several stages. First, the photo is transformed into a color space YCbCr.
Then it is divided into squares to determine the upper range of the color spectrum. Finally, the colors and brightness are coded. JPEG uses a "lossy" compression system and discrete cosine transform technology. The file compression ratio is in the range from to In this case, the reduction in image quality can vary from insignificant to substantial.
