JPEG (Joint Photographic Experts Group) is a widely used image compression format. It uses a lossy compression algorithm to reduce the file size while maintaining reasonable image quality. To understand the “Corrupt JPEG data” error, it’s important to have a basic understanding of the JPEG fi...

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. png image-compression image-compressor image-encoder lossless-image-compr...
It’s worth highlighting that despite WebP’s inherent size advantages, Tinify’s optimization canfurther decrease the file size. The intelligent algorithm ensures that there are no visible differences while more savings are made. What does TinyPNG do?

We've added a new algorithm to detectfree standing objectson plain backgrounds. The API willadd background spaceor remove superfluous areas when the aspect ratio is changed. This way the object in your image will remain free-standing and does not get cut-off at the edges when resizing. ...
JLS - JPEG-LS Lossless and Near Lossless.This raster image format is developed by the Joint Photographic Experts Group (JPEG). JPEG-LS algorithm is based on LOCO-l (low complexity lossless compression for images). LEAD supports compressing and decompressing lossless and near lossless i...

This is a pytorch implementation of differentiable jpeg compression algorithm. This work is based on the discussion in this paper. The work relies heavily on the tensorflow implementation in this repository Requirements Pytorch 1.0.0 numpy 1.15.4 Use DiffJPEG functions as a standard pytorch module/...
