Caesium is an image compression software that helps you store, send and share digital pictures, supporting JPG, PNG, WebP and TIFF formats. You can quickly reduce the file size (and resolution, if you want) by preserving the overall quality of the image.

Free Lossless Image Format

JPEG XL image format reference implementation

Limited Error Raster Compression

CharLS, a C++ JPEG-LS library implementation

Free Universal Image Format

NBLI is a fast, better lossless image compression algorithm. The optimized version (fNBLI) can get 1.5x compression ratio, 8x faster encoding, and 1.2x faster decoding compared to PNG. It can also beat the SOTA JPEG-XL on photographs.

This is script and implementation of frontend image compression, convert, rotate, resize based on codecs in Google/Squoosh. All codecs are copy from the Squoosh repo without modifying. if you want to pre-process images before uploading them to the server, please use this repo for reference

Image Compression using Huffman Coding

This project showcases real-time image and video compression using OpenCV in C++. The code allows users to choose between image or video compression and specify the compression level. The project utilizes multithreading to achieve efficient compression performance.
