when he stumbled upon idea of how to make a simple lossless compression algorithm, resulting in the Quite OK Image Format, which seems to offer comparable file sizes to the PNG format but is so ...

Since text files and the like have a ton of whitespace in them, modern compression algorithms can shrink them to some ...

They say the new algorithm is up to ten times faster ... and just send along the major players, reducing file sizes. This works for compression because most media is “sparse.” ...

Several algorithms for data compression may be ... his knowledge of steganography to create a wholly unique form of file compression, perhaps one that may gain greater notoriety among other ...

File compression reduces a file's size without significantly compromising its quality. Compression algorithms essentially ...

as in jpg files. Lossless photo compression works similarly to zip and rar compression: it packs data with a reversible algorithm. Lossy compression often saves more space, but cannot be reversed ...

But algorithms used on the Linux command line to compress or archive user files have to be able to reproduce the original content exactly. In other words, they have to be lossless. How is that done?

bzip2 typically achieves better compression than gzip, especially with text files. Moderate Speed: It's slower than gzip but compensates with better space savings. xz, based on the LZMA algorithm, is ...

and use a file compression tool and the Lempel–Ziv–Markov chain algorithm (LMZA) to squash it down to just 257 bytes, but that's on a modern computer, with an ultra-fast, multicore processor ...
