    Using PNG instead of a high-quality JPEG for such images would result in a large increase in filesize with negligible gain in quality. In comparison, when storing images that contain text, line art, or graphics – images with sharp transitions and large areas of solid color – the PNG format can compress image data more than JPEG can.

    PNG can store gamma and chromaticity data, as well as ICC profiles, for accurate color matching on heterogeneous platforms. Animated formats derived from PNG are MNG and APNG, which is backwards compatible with PNG and supported by most browsers. JPEG 2000.

    JPEG. JPEG ( / ˈdʒeɪpɛɡ / JAY-peg, short for Joint Photographic Experts Group) [2] is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality.

    JPEG XL – an image file format developed since 2019 (standardization completed since 2022) and based on Google PIK [Wikidata] and Cloudinary FLIF (itself based upon FUIF [Wikidata]) claiming to outperform PNG, WebP, BPG and JPEG 2000 for lossless encoding at least; WebP – an image file format based on the VP8 and VP9 video formats; References

    Instead, just eliminate JPEG artifacts as much as possible and convert to 24-bit PNG. Using the posterize option of your graphics editor with a high setting (like 40) may further reduce filesize and eliminate more artifacts without visibly reducing image quality. You can try using pngquant on the 24-bit result; this produces indexed mode images ...

    However, raw has numerous advantages over JPEG such as: Many more shades of colors compared to JPEG files – raw files have 12 or 14 bits of intensity information per channel (4096-16384 shades), compared to JPEG's gamma-compressed 8 bits (256 shades). Higher image quality.

    Format conversion: convert an image from one format to another (e.g. PNG to JPEG). Transform: resize, rotate, crop, flip or trim an image. (Applies these without generation loss on JPEG files, where possible.) Transparency: render portions of an image invisible. Draw: add shapes or text to an image. Decorate: add a border or frame to an image.
