Not every compression method works for every file, and you can increase efficiency by changing the file type, ... modern compression algorithms can shrink them to some stupendously small sizes.

Compression algorithms essentially identify and eliminate redundant data within the file. Compressed files take up less storage space and are faster to transfer, locally or over a network.

Several algorithms for data compression may be more familiar ... What is important to avoid, however, is lossy file compression that can wreak havoc on quality during the compression stage.

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 ...

MIT researchers could speed up file compression using an improved Fourier transform algorithm. A group of MIT researchers believe they’ve found a way to speed up audio, video, and image ...

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 ...

Google has developed a new open-source image compression algorithm that it says can reduce the size of JPEG images by 35 percent. The algorithm, dubbed Guetzil (that's Swiss German for cookie), is ...

Google has announced a new open-source encoder which utilizes an algorithm that enables it to compress JPEG files by 35% more than currently available methods with minimal loss in quality.
