PNG

Portable Network Graphics

PNG stands for Portable Network Graphics, and it is a popular raster graphics file format that supports lossless data compression. PNG was created as an improved, non-patented replacement for GIF, and is the most used lossless image compression format on the Internet. It supports a range of colors, including full-color and grayscale images, and also supports transparency, making it suitable for graphics, logos, and detailed artwork.

JXL

JPEG XL (ISO/IEC 18181)

JXL stands for JPEG XL, a next-generation image coding standard developed by the Joint Photographic Experts Group (JPEG). JPEG XL is designed to provide efficient compression for both lossless and lossy image storage, offering high image quality at lower file sizes compared to previous standards. It supports a wide range of features including high dynamic range, wide color gamut, and progressive decoding, making it suitable for use in various applications from web graphics to professional photography. Despite its advantages, as a newer standard, JPEG XL may not yet have widespread support across all platforms and software.
