If now we try the same, but using Lossy method, the AVIF format wins again: If we zoom in, we can see the difference. We see that AVIF is slightly bigger but the color transitions on the letters are smoother with AVIF. Left – AVIF / Right – WebP Test #3: JPG 994×559Īnother JPG with a different size but converting it to WebP and AVIF using ShortPixel‘s API as well with our Glossy method. That’s why the image, not zoomed in, will appear less pixelated. On the following screenshot (which is zoomed in) one can see that around the small “UNIVERSITY OF” letters, the AVIF shows less artifacts as a result of the optimization. For roughly the same size, it is less pixelated than the WebP equivalent. Here we have a WordPress thumbnail, size 150×150, and we convert it to WebP and AVIF using ShortPixel‘s API and its Glossy optimization quality. Left – AVIF / Right – WebP Test #2: JPG 150×150 AVIF looks smoother and with less optimization artifacts. If we zoom in the WebP and the AVIF files, we can see a clear difference in quality. AVIF: 547 KB ( 91% smaller than the JPG).WebP: 844 KB ( 86% smaller than the JPG).We start by taking a CR2 file, an uncompressed format for pictures taken with a Canon camera, and convert them to JPG, WebP and AVIF using Convertio. Remember that for now you can only see AVIF images on Google Chrome or Firefox! Test #1: CR2 Feel free to open each image on a new tab to appreciate all the details and optimization artifacts.Īt the end of the article we will link to a ZIP file with all the original pictures and results we mention here. Since it is very easy to write a few numbers and statistics, we’ve gone ahead and run quite a few tests comparing how each format is performing. We also find, of course, bugs and problems that must be worked out to ensure the AV1 image file format outshines its competitors, although this is something normal one can expect from every new software. On browsers, for example, we can only enjoy AVIF on Google Chrome and, if you enable a flag, on Firefox: The first version was released in February 2019, and because of this, only very few applications support it. The main and probably only drawback we can find nowadays, in 2020, is that the format is very new. Here at ShortPixel we are already working on implementing the AVIF format on our services and plugins, so you can start enjoying the benefits of it as soon as possible!Īs of now, you can already use the parameter “ to_avif” when calling our API to get an image in AVIF format as described in this article: ShortPixel’s API parameters. For those who like technical reading, you’ll love it. On February 2020, Netflix published a blog article with objective measurements on AVIF’s image quality & compression efficiency in comparison to JPEG. We can find now AVIF support in Google Chrome, VLC or GIMP, and companies like Microsoft are jumping in the train. The first images in AVIF format were published in February 2018 by Netflix, and since then more applications and companies have been adding support for it, albeit rather slowly. Behind it we find companies like Amazon, Google, Apple, Intel or Samsung, so it is no short of resources.It was created in a royalty-free format, which will speed up all the adoptions, as developers won’t have to deal with legal or financial barriers.It provides the highest lossless and lossy compression possible.It supports HDR, transparency and wide color gamut.Now, AVIF promises images 50% smaller than JPG, and still keeping the same image quality. A few years ago, WebP came on the scene, developed by Google, delivering images 30% smaller than JPG, keeping the same image quality. We could say that, currently, the most popular image file formats for web are JPG and PNG. Behind AOMedia we find big companies like Netflix, Google, Facebook, Apple or Microsoft. AOMedia’s goal is to develop open, royalty-free technology for multimedia delivery, which means that nobody will have to pay anybody to use the new AVIF format (as opposed to JPG, for example). Experts believe that it is the next step in media compression. AVIF is an image file format developed by Alliance for Open Media which is supposed to make our images smaller while keeping the same image quality.
