    Zstandard

    Zstandard

    Zstandard - Fast real-time compression algorithm

    ...The reference library offers a very wide range of speed / compression trade-off, and is backed by an extremely fast decoder (see benchmarks below). Zstandard library is provided as open source software using a BSD license. Its format is stable and published as IETF RFC 8478. The negative compression levels, specified with --fast=#, offer faster compression and decompression speed in exchange for some loss in compression ratio compared to level 1, as seen in the table above. Zstd can trade compression speed for stronger compression ratios. ...

    Brotli

    Brotli

    Brotli compression format

    Version 1.0.9 contains a fix to "integer overflow" problem. This happens when "one-shot" decoding API is used (or input chunk for streaming API is not limited), input size (chunk size) is larger than 2GiB, and input contains uncompressed blocks. After the overflow happens, memcpy is invoked with a gigantic num value, that will likely cause the crash. Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm,...

    Snappy

    Snappy

    A fast compressor/decompressor

    Snappy is a compression/decompression library. It does not aim for maximum compression, or compatibility with any other compression library; instead, it aims for very high speeds and reasonable compression. For instance, compared to the fastest mode of zlib, Snappy is an order of magnitude faster for most inputs, but the resulting compressed files are anywhere from 20% to 100% bigger. Snappy is intended to be fast. On a single core of a Core i7 processor in 64-bit mode, it compresses at...

    Compressor.js

    Compressor.js

    JavaScript image compressor

    Compressor.js is a lightweight JavaScript library for in-browser image compression that allows developers to reduce file sizes before uploading images to a server, improving performance and user experience. It works by taking an input image (such as from a file input) and resizing or reencoding it on the client side according to developer-specified options like maximum width, height, quality, and MIME type. Because compression happens in the browser, users upload smaller images without...
