The loss of data occurs in this filtering phase by increasing redundant patterns along scan lines to subsequently improve the actual compression and decrease the file size. The 'lossiness' comes in when the GIF is first filtered or altered so that the image can then compress more efficiently. The compression algorithms used in GIFs are lossless, and there is no loss of data when compressing this palette-based format. You can convert to an animated AVIF only from an animated GIF or video.

Converting from animated WebP or animated PNG to animated AVIF is not supported.

Animated AVIF is not currently supported by f_auto.WebP, even in browsers where animated WebP is supported. gif file that is defined as an animated GIF, but has only one frame, then f_auto will always deliver it as a. Single-frame animated WebP is not supported.Although animated PNGs are supported only in some browsers and versions, animated PNGs are backward compatible, so all browsers can show the first frame of an animated PNG, even if they don't directly support animated PNGs.For example, delivering the animated GIF called kitten_fighting as an animated WebP: png and set the flag parameter to awebp or apng ( fl_awebp or fl_apng in URLs). To deliver an animated WebP or PNG instead of an animated GIF, change the file extension to. To deliver an animated AVIF instead of an animated GIF, change the file extension to. Animated GIF converted to animated WebP can provide between 64% byte savings (lossy WebP), to 19% byte savings (for lossless WebP).Animated GIF converted to animated AVIF can provide over 90% byte savings.AVIF requires fewer bytes than WebP, which itself requires fewer bytes than GIF and PNG.GIF and PNG only support lossless compression. AVIF and WebP support both lossy and lossless compression (a single animation can combine lossy and lossless frames), well-suited to animated images created from real-world videos.Animated PNG and WebP support 24-bit RGB color with an 8-bit alpha channel, compared to AVIF's 12-bit color depth and GIF's 8-bit color and 1-bit alpha.Animated AVIF is based on the AV1 video codec that was released in 2019 and shares the same compression and quality levels.Animated PNGs are supported on most, but not all, browsers. Animated WebPs and animated AVIFs are currently supported only in Chrome and Opera. Animated GIFs are universally supported.When deciding which format to use, consider the following: You can convert animated images to other animated image formats.
