In plain words
A luma dependent chroma compression algorithm is an image compression technique that launched in February 2026. It works by compressing color information based on brightness levels, allowing for smaller file sizes while maintaining image quality. The tool is designed for photographers, developers, and anyone working with digital images who needs efficient compression methods. It is available at bitsnbites.eu.

In this article I will describe a technique that can often compress the chroma data of an image to less than 0.5 bits per pixel on average, without visible artifacts. A common technique in the field of image and video compression is to convert RGB images to YCrCb before compression. Instead of representing color as red, green and blue channels, we represent them as luminance (Y) and chrominance (Cr and Cb) channels. One of the main advantages is that Y contains most of the information, while the chroma channels can be represented in a lower resolution without the human eye detecting it (something that was actually used as early as in the 1930’s-1960’s for color television ,…from bitsnbites.eu

Hello my name is Ben Ward for the past 3 years I have been remastering the financial game Wall Street Raider created by Michael Jenkins originally on DOS in 1986. It has been a rough journey but I finally see the light at the end of the tunnel. I just recently redid the website and thought maybe the full story of how this project came to be would interest you all. Thank you for reading.
