Which algorithm is used for image compression?

Image files can take up a lot of space, so computers employ a range of algorithms to compress image files. For the simplest of images, computers can use a compression algorithm called run-length encoding (RLE).

What is the best compression algorithm?

The fastest algorithm, lz4, results in lower compression ratios; xz, which has the highest compression ratio, suffers from a slow compression speed. However, Zstandard, at the default setting, shows substantial improvements in both compression speed and decompression speed, while compressing at the same ratio as zlib.

Is JPEG a compression algorithm?

JPEG stands for Joint Photographic Experts Group, which was a group of image processing experts that devised a standard for compressing images (ISO). So, JPEG (or JPG) is not really a file format but rather an image compression standard.
