Not every compression method works for every file, and you can increase efficiency by changing the file type, ... modern ...

Compression algorithms. Compression is not a one-size-fits-all issue. Some compression tools are “lossy,” such as those used to reduce the size of mp3 files while allowing listeners to have ...

A group of MIT researchers believe they’ve found a way to speed up audio, video, and image compression by improving on the Fourier Transform. They say the new algorithm is up to ten times faster ...

This compression may be lossless, such as in png files, or lossy, as in jpg files. Lossless photo compression works similarly to zip and rar compression: it packs data with a reversible algorithm.

To compress: bzip2 filename To decompress: bunzip2 filename.bz2. xz: The Compression Powerhouse Background. xz, based on the LZMA algorithm, is relatively new but has gained significant traction for ...

For example, I can make a 256 kB text file, containing over 260,000 identical characters, and use a file compression tool and the Lempel–Ziv–Markov chain algorithm (LMZA) to squash it down to ...

Imagine there is a 10GiB file that is extremely compressible but only 80MiB of the first 500MiB can be compressed, the SMB compression algorithm would just give up compressing the file altogether ...
