There are generic compression algorithms available, including Google’s open source Brotli. Lepton, written primarily in C++, is tuned to work with images, and it cuts off 22 percent of file size ...

Compression algorithms, such as LZ77 and Huffman, analyze data for redundancies and patterns, allowing them to represent those patterns more efficiently with fewer bits.

People store large quantities of data in their electronic devices and transfer some of this data to others, whether for professional or personal reasons. Data compression methods are thus of the ...

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?

"I began experimenting with file-compression algorithms to see if we could shrink files to the point where they could be sent over standard phone lines," he said.

Google just launched Zopfli, a new open source compression algorithm that can compress web content about three to eight percent more densely (PDF) than the standard zlib library. Because Zopfli is ...

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 ...
