PyTorch implementation of PerCo (Towards Image Compression with Perfect Realism at Ultra-Low Bitrates, ICLR 2024)
The Cyber Swiss Army Knife - a web app for encryption, encoding, compression and data analysis.
CyberChef is a simple, intuitive web app for carrying out all manner of "cyber" operations within a web browser. These operations include simple encoding like XOR and Base64, more complex encryption like AES, DES and Blowfish, creating binary and hexdumps, compression and decompression of data, calculating hashes and checksums, IPv6 and X.509 parsing, changing character encodings, and much more.
convert images super fast.
Modern formats like WebP, AVIF, and JPEG-XL, convert to reduce the image size.
Compress WebP, PNG, JPEG and Gif images intelligently.
Pic Smaller is a super easy-to-use online image compression tool. Its UI is intuitive and supports compression configuration. At the same time, because it is purely local compression without any server-side logic, it is completely safe.
Convert & compress everything in 2 clicks!
File Converter is a very simple tool which allows you to convert and compress one or several file(s) using the context menu in windows explorer.
Fast real-time compression algorithm.
Zstandard, or zstd as short version, is a fast lossless compression algorithm, targeting real-time compression scenarios at zlib-level and better compression ratios. It's backed by a very fast entropy stage, provided by Huff0 and FSE library.
Brotli is a generic-purpose lossless compression algorithm that compresses data using a combination of a modern variant of the LZ77 algorithm, Huffman coding and 2nd order context modeling, with a compression ratio comparable to the best currently available general-purpose compression methods. It is similar in speed with deflate but offers more dense compression.
Zstandard is a fast compression algorithm, providing high compression ratios. It also offers a special mode for small data, called dictionary compression. 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 8878.
LZ4 is lossless compression algorithm, providing compression speed > 500 MB/s per core (>0.15 Bytes/cycle). It features an extremely fast decoder, with speed in multiple GB/s per core (~1 Byte/cycle). A high compression derivative, called LZ4_HC, is available, trading customizable CPU time for compression ratio. LZ4 library is provided as open source software using a BSD license.
Compress PNG, JPG, and More.
With this online image compressor, it is super easy to compress your JPG or PNG images at a fast speed. This is a browser-based image processor that helps you compress your images with a negligible waiting time. The best thing about this image process is that it is secure, private and works offline with zero limitations. Moreover, you also don't harm the environment because there is literally no carbon emission in the process.
