Just wondering, is there a "lossless" conversion from PNG/JPEG/etc to AVIF? Kinda like Lepton[1] but just re-compressing without further loss of details. [1] h

- IAmLiterallyAB 6y agoNot sure about AVIF but JPEG XL has exactly that
- markdog12 6y agoYes, avif has lossless. https://squoosh.app/ https://squoosh.app/ has both avif and jpegxl if you want to try it out.
- JyrkiAlakuijala 6y agoAVIF has pixel-based lossless. AVIF's pixel-based lossless seems not very exciting at first look since it performs worse than WebP lossless. https://www.reddit.com/r/jpegxl/comments/fjddrr/lossless_image_formats_comparison_webp_jpeg_xl/ https://www.reddit.com/r/jpegxl/comments/fjddrr/lossless_ima... AVIF does not support recompression of JPEG files like Lepton, Brunsli, PackJPG, 7zip media layer (using Brunsli), and JPEG XL. AVIF works very well in the high density low-bit-rate compression. The flip side there is loss of detail.
