Ultra Compression Params Generator
GUI and generator of the best compression parameters for perspective compressors: BSC and Kanzi. It uses all possible compression parameters and at the end it creates the smallest possible archive. BSC is a high performance file compressor based on lossless, block-sorting data compression algorithms. Multiple algorithms that allows software fine-tuning for maximum speed or compression efficiency. Kanzi is a modern, modular, portable and efficient lossless data compressor implemented in C++. Modern: state-of-the-art algorithms are implemented and multi-core CPUs can take advantage of the built-in multi-threading. Modular: entropy codec and a combination of transforms can be provided at runtime to best match the kind of data to compress. Unlike the most common lossless data compressors, Kanzi uses a variety of different compression algorithms and supports a wider range of compression ratios as a result. Most usual compressors do not take advantage of the many cores and threads available on modern CPUs. Kanzi is multithreaded by design and uses several threads by default to compress blocks concurrently.

Ultra7z Video to AV1/H265/H264 Converter
Video converter to modern formats AV1/H.265(HEVC)/H.264(AVC) with fast GPU acceleration for free! AV1 has high compression ratio – better than H.256/H.264. It allows you to save disk space for video storage. AOMedia Video 1 (AV1) is a modern open video format that provides superior lossy and lossless compression for video files (replacement for H264/265). One of the interesting features is that you can specify the desired file size, for example, 1400 MB for a movie (or as a percentage, for example, 80% of the original size), and the program will automatically select the conversion settings for the best quality. Support for encoding and decoding on AMD and Nvidia video cards provides very fast video conversion (several times faster than on the processor). Multithreading support also speeds up the video encoding process. Important: AV1, unlike H. 265 (HEVC), is open, meaning no one has to pay to use it. It uses program ffmpeg.exe. Batch processing of files and drag-n-drop. Program optimizes your file to new one with «_optimized» name ending (source file will remain intact). Reduce the size of your video files in one click! AV1 video files are 50% smaller in size compared to H.264 and 30% to H.265.

Ultra7z JPEG Archiver
Archiver of JPEG-pictures to smaller JPEG XL files (*.jxl)! You can add to archive or extract your original photos from archive. Lossless JPEG transcoding – about 20% smaller. Existing JPEG files can be losslessly transcoded to JPEG XL, significantly reducing their size. These can be restored into the exact same JPEG file, ensuring backward compatibility with existing JPEG-based applications. These features are intended to provide a smooth transition from legacy JPEG platforms to the modern JPEG XL. Both the transcoding and restoration are computationally efficient. JPEG XL is a modern image format that provides superior lossy and lossless compression for images. Using JXL, webmasters and web developers can create smaller, richer images that make the web faster. It uses program cjxl.exe. Batch processing of files (drag-n-drop). Program optimizes your file to new one with «_optimized» name ending (source file will remain intact). Reduce the size of your image files in one click with or without quality loss!
