![]() another unfair Quality 70 with Commpression of 6 & Mixed compression (lossy and lossles).an unfair mixed mode (lossless and lossy compression) with a quality of 70.A quality of 70 with default compression of 4 (lossless).quality of 70 and 6 (-m 6) for the compression mode.You'll have to test those out for specific images, or use the defaults such as I have. These could with adjustments and tweaking produce smaller or in some instances bigger files. Things such has -kmin, -kmax - which specify the minimum and maximum distance between consecutive key frames and can improve decoding performance - or adjust the deblocking filter -f from the docs suggested 50. I didn't dive into the different CLI options available for gif2webp. The same reference gif was converted to a webp using three different options and WebP Encoder version: 0.6.0 (WebP Mux version: 0.4.0). Depending on your OS again if you use the CLI version of apngopt you'll get versions ranging from 1.1 to 1.4.If you install gif2apng through your OS's package manager (ie: apt-get/apt) depending on your OS's you'll more than likely get version 1.7.I haven't had the time to see if the GUI and CLI differ in anyway so that'll be up to you unless you're ok with the output of the GUI then keep on keepin on! On a windows machine just use the GUI they package from sourceforge.APNG Filesize Resultsįilesize of APNG after using APNGOPT Compression Type I'll use the "default" of 15 for each apng that was converted with the defaults above and 100 for all the 100 iterations. This too offers differing amount of iterations. Be prepared to set aside a pretty big chunk of time if you do this on your computer :).Īfter converting the GIF to an Animated PNG I'll also run it through APNGOPT. Increasing the iterations for either of the compression algorithms will also increase how long it takes to convert your image to an APNG. Depending on your server specs or locally on your own computer and it's specs Zopfli will take a long time. For both 7zip and zopfli I'll use the "default" iterations of 15 and a more aggressive version of 100. Each compression option besides zlib allows you to set an iteration amount which defaults to 15. We have zlib, 7zip and Zopfli compression. Gif2apng offers three different options for converting a GIF to an animated PNG. Please try I don't want to dismiss APNG as much as I think I'm probably coming off as. ![]() Maybe you can convert the GIF on this page to an APNG and get better results. Here are the relevant details of the unoptimized GIF:īefore we can even embark on this trip we have to convert the GIF above to an APNG and an Animated Webp. That was a 1080p video stripped down to about 5 seconds and resized to a width of 800. The GIF I'm using for this post comes from my post on Converting MP4 To Webm. So lets actually test that instead of me spouting off haha. Is that the case though? I assume the smaller webp gets downloaded to the client faster then it'll start decoding faster. That assumes the larger APNG will load faster than the smaller webp. This of course is anecdotal and I'm not as familiar with apng as the creators and others may be so they may be able to squeeze more out of an apng than I can.Īll that being said I've heard and read people say "APNG might be bigger but webp takes longer to decode in the browser". In all my findings (linked below where the source Gif comes from) animated webp beats apng in filesize each and every time. Varying posts and sites have different conclusions on when to use APNG versus an animated Webp. With Chrome now supporting Animated PNG as of Chrome 59 we have two image formats that can supplant the old and tired GIF format.
