What is AVIF?
AVIF is an open, royalty-free image file format specification for storing images or image sequences compressed with AV1. While JPEG relies on technology from the 90s and WebP on tech from 2010, AVIF leverages the AV1 video codec, which was built for the 4K and 8K streaming era.
Because it is royalty-free, big tech players like Google, Apple, Microsoft, and Netflix have all thrown their weight behind it. It is essentially a "super-compressed" container that can handle everything from simple icons to high-dynamic-range (HDR) photography.
🎯 Industry Backing: AVIF is supported by the Alliance for Open Media (AOMedia), which includes Google, Apple, Microsoft, Netflix, Amazon, and Meta. This unprecedented industry support ensures long-term viability.
The Technical Power of AV1
The magic of AVIF lies in its use of the AV1 codec's sophisticated "tools." Unlike JPEG, which sees an image as a collection of 8×8 blocks, AVIF uses a much more flexible approach.
Intra-prediction and Film Grain Synthesis
AVIF uses advanced intra-prediction, which allows the encoder to describe complex patterns more efficiently. Furthermore, it features "Film Grain Synthesis." Instead of trying to compress the "noise" or grain in a photo (which takes up a lot of data), AVIF removes the grain, compresses the smooth image, and then adds the grain back digitally at the end. This keeps photos looking natural while slashing the file size.
Chroma Subsampling
AVIF supports full 4:4:4 chroma subsampling, ensuring that color transitions are razor-sharp. This is particularly important for graphics with text or high-contrast interfaces where color "bleeding" can be an issue.
Technical Edge: AVIF's film grain synthesis is revolutionary. Traditional formats waste bandwidth encoding natural grain; AVIF strips it out, compresses efficiently, then reapplies it algorithmically—saving 10-15% in file size.
Why AVIF Beats WebP and JPEG
The numbers are hard to ignore. In most industry tests, AVIF achieves:
- 50% smaller files than JPEG for the same visual quality
- 20% to 30% smaller files than WebP
In the world of mobile browsing, where every kilobyte matters for page load speed, these savings are revolutionary. A page that previously took 3 seconds to load with JPEGs might load in under 1 second using AVIF, drastically reducing bounce rates.
📊 Real-World Impact: Netflix reported a 40% reduction in image bandwidth after switching to AVIF for promotional imagery. For a streaming platform serving billions of images, this translates to massive infrastructure savings.
Advanced Features: HDR and 12-bit Color
One of the standout features of AVIF is its support for High Dynamic Range (HDR). While JPEG is limited to 8-bit color (standard), AVIF supports 10-bit and 12-bit color depth.
This means AVIF can display more detail in the brightest highlights and the deepest shadows. If you are viewing images on a modern OLED or HDR-capable monitor, AVIF images look significantly more lifelike, with smoother gradients and more accurate colors.
HDR Advantage: With 12-bit color support, AVIF can represent 68.7 billion colors compared to JPEG's 16.7 million. This 4,000x increase eliminates banding in gradients and enables true HDR photography on the web.
Browser and Software Support
In 2026, AVIF support is nearly universal across modern browsers:
- ✅ Chrome: Full support since version 85 (2020)
- ✅ Firefox: Full support since version 93 (2021)
- ✅ Edge: Full support since version 121 (2024)
- ✅ Safari: Full support since iOS 16 and macOS Ventura (2022)
Design Tools: Adobe Photoshop, GIMP, and Figma now all support AVIF natively, making it easy to export and work with AVIF files in your creative workflow.
⚠️ Legacy Considerations: For older browsers and systems, use the HTML <picture> element to serve AVIF to modern browsers while providing JPEG/PNG fallbacks for legacy support.

Conclusion: Implementing AVIF in 2026
AVIF is no longer the "format of the future"—it is the format of the now. If you are looking to maximize your Core Web Vitals and provide the best possible visual experience for your users, you should be migrating your image library to AVIF.
The combination of royalty-free licensing, superior compression, and HDR support makes it the most capable image format ever released. Start by converting your largest "hero" images to AVIF and watch your site speed scores soar.
🚀 Implementation Strategy: Start with your homepage hero images and largest assets. These provide the biggest performance wins. Use progressive enhancement with <picture> elements to serve AVIF with JPEG fallbacks.

Is AVIF better than WebP?
Yes, in terms of compression efficiency and color depth, AVIF outperforms WebP. An AVIF file is typically 20-30% smaller than a WebP file of the same quality, and AVIF supports 12-bit HDR while WebP is limited to 8-bit.
Can I use AVIF for everything?
While it is excellent for photos and web graphics, AVIF can take more CPU power to encode (create) than JPEG. For a small blog, this doesn't matter, but for a massive platform like Facebook, the server costs of encoding millions of AVIFs are a consideration.
How do I open an AVIF file?
Most modern browsers can open them if you drag the file into a tab. Additionally, Windows 11 and recent versions of macOS support AVIF previews in the file explorer.
Does AVIF support animation?
Yes! Much like WebP, AVIF supports animated sequences (AVIS), which are far more efficient than GIFs and support full 24-bit color with transparency.
Is AVIF good for SEO?
Absolutely. Because AVIF reduces file size without losing quality, your pages load faster. Google rewards fast-loading pages with better search rankings, making AVIF an excellent choice for SEO optimization.
