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 ...

Not every compression method works for every file, and you can increase efficiency by changing the file type, codec, or program used.

"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.

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 ...

Q: What accounts for the difference in yield between compression and file deduplication? A: With compression you are using some algorithm or other to reduce the size of a particular file by ...

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.

Windows NTFS file system can compress your file system using the built-in compact.exe tool. Use CompactGUI to compress installed software & applications and save Disk Space.

An algorithm based on scale-specific quantization of biorthogonal wavelet coefficients was developed for the compression of high-resolution digitized mammograms.
