In our implementation in Image Resizing we’re supporting only still standard-range images. Browsers will support only a fraction of these features. Most of its features are for smartphone cameras, such as "live" photos, depth maps, bursts, HDR, and lossless editing. Our Image Resizing is implemented in Rust, so we've chosen the rav1e encoder to create a pure-Rust implementation of AVIF. This is a sign of a healthy adoption and a prerequisite to be a Web standard. AVIF and AV1 are already ahead with multiple independent implementations: libaom, Intel SVT-AV1, libgav1, dav1d, and rav1e. Non-standard image formats usually can only be created using their vendor's own implementation. #Cloudflare image resize freeAV1 is free to use by anyone, and the alliance of tech giants behind it will defend it from patent troll's lawsuits. This has created a huge incentive for Web giants like Google, Netflix, and Amazon to get behind the royalty-free alternative. Nowadays, when video is mostly consumed via free browsers and apps, the old licensing model has become unsustainable. Costs and complexity of patent licensing used to be acceptable when videos were published by big studios, and the cost could be passed on to the customer in the price of physical discs and hardware players. It's covered by thousands of patents, owned by hundreds of companies, which have fragmented into two competing licensing organizations. #Cloudflare image resize softwareIn countries that allow software patents, H.265 is illegal to use without obtaining patent licenses. The difference is that HEIC is based on a commercial, patent-encumbered H.265 format. AVIF and HEIC offer similar compression performance. Latest GPUs from Nvidia, AMD, and Intel already have hardware decoding support for AV1.ĪVIF uses the same HEIF container as the HEIC format used in iOS’s camera. The AV1 codec is already seeing faster adoption than the previous royalty-free codecs. However, this time Apple is one of the companies in the Alliance for Open Media, creators of AVIF. Apple hasn't announced whether Safari will support AVIF. It’s a work in progress in other Chromium-based browsers, and Firefox. Safari only added WebP support very recently, 10 years after Chrome.Ĭhrome 85 supports AVIF already. VP8 and WebP suffered from reluctant industry adoption. They are usually correlated, so a good guess gives smaller file sizes and sharper edges. AVIF uses the brightness channel to guess what the color channel may look like. Most image formats store brightness separately from color hue. #Cloudflare image resize fullAVIF supports 10- and 12-bit color at full resolution, and high dynamic range (HDR).ĪV1 also uses a new compression technique: chroma-from-luma. This causes edges of saturated colors to be smudged or pixelated in WebP. WebP is limited to 8-bit color depth, and in its best-compressing mode of operation, it can only store color at half of the image's resolution (known as chroma subsampling). WebP uses the old VP8 version, while AVIF is based on AV1, which is the next generation after VP10. These two formats are technically related: they're both based on a video codec from the VPx family. #Cloudflare image resize upgradeWebP is over 10 years old, and AVIF is a major upgrade over the WebP format. One of the big things AVIF does is it fixes WebP's biggest flaws. Compression and image quality in AVIF is better than in all of them, and by a wide margin. However, these formats offered only modest compression improvements, and didn't always beat JPEG on image quality. There have been many previous attempts at replacing JPEG, such as JPEG 2000, JPEG XR and WebP. It's doing remarkably well for its age, and it will likely remain popular for years to come thanks to its excellent compatibility. #Cloudflare image resize isoThe compression in AVIF is so good that images can reduce to half the size of JPEG and WebP What is AVIF?ĪVIF is a combination of the HEIF ISO standard, and a royalty-free AV1 codec by Mozilla, Xiph, Google, Cisco, and many others.Ĭurrently, JPEG is the most popular image format on the Web. Improved image compression can save bandwidth and improve overall performance of the web. More than a half of an average website's bandwidth is spent on images. It's supported in Chrome desktop today, and support is coming to other Chromium-based browsers, as well as Firefox. It compresses images significantly better than older-generation formats such as WebP and JPEG. We've added support for the new AVIF image format in Image Resizing.
