What Makes AVIF Special?
AVIF (AV1 Image File Format) is the newest and most efficient image codec for the web, developed by the Alliance for Open Media—a consortium that includes Google, Mozilla, Netflix, and Amazon. It was designed specifically to replace JPEG and offer better compression than WebP.
Why Top Websites Choose AVIF:
50% Smaller Files Than JPEG
Same visual quality at half the file size means faster downloads and lower bandwidth costs
Improved Core Web Vitals
Smaller images directly improve LCP (Largest Contentful Paint) scores for better SEO
Superior Image Quality
Supports HDR, wide color gamut, and 12-bit color depth for stunning visuals
90%+ Browser Support
Chrome, Firefox, Safari, and Edge all support AVIF natively since 2020-2022
Performance Benefits for Your Website
Faster Page Load Times
A typical 500 KB JPEG becomes 250 KB as AVIF. With multiple images per page, this can reduce total page weight by 40-60%, dramatically improving load times especially on mobile networks.
Real example: An e-commerce product page with 20 images goes from 10 MB → 5 MB
Reduced Bandwidth Costs
For high-traffic websites, bandwidth is expensive. 50% smaller files = 50% lower bandwidth bills. Sites serving millions of images monthly can save thousands of dollars.
Cost savings: 100 TB/month bandwidth → 50 TB/month with AVIF
Better Core Web Vitals
Google's Core Web Vitals are ranking factors. AVIF directly improves LCP (Largest Contentful Paint) by loading hero images faster, and reduces CLS (Cumulative Layout Shift) with faster rendering.
SEO impact: Better CWV = higher search rankings
Improved User Experience
Faster loading images mean users see content sooner, reducing bounce rates. Studies show 1-second delay = 7% conversion loss. AVIF helps eliminate that delay.
Result: Higher engagement + lower bounce rates
How AVIF Improves SEO Rankings
Direct SEO Benefits:
1. Page Speed is a Ranking Factor
Google officially confirmed page speed affects rankings. AVIF's 50% file size reduction directly improves speed metrics, giving your site a competitive edge.
2. Core Web Vitals Score Higher
LCP (Largest Contentful Paint) measures when your main content loads. Hero images are often the LCP element. Smaller AVIF files = faster LCP = better rankings.
3. Mobile-First Indexing
Google indexes mobile versions first. Mobile users on 4G/5G benefit massively from smaller images. AVIF helps your mobile experience rank better.
4. Lower Bounce Rates
Faster pages retain users longer. Google tracks user engagement signals. Better UX from AVIF → lower bounce rates → positive ranking signal.
AVIF vs JPEG vs WebP: Real Numbers
| Format | File Size (1920x1080) | Quality | Browser Support |
|---|---|---|---|
| AVIF | 250 KB ⭐ | Excellent | 90%+ |
| WebP | 320 KB | Very Good | 95%+ |
| JPEG | 500 KB | Good | 100% ⭐ |
| PNG | 2.1 MB | Lossless | 100% |
💡 Recommendation: Use AVIF with JPEG/WebP fallbacks for maximum compatibility and best performance. Modern CDNs can handle this automatically.
How to Use AVIF on Your Website
HTML Picture Element (Recommended)
Use the <picture> element with multiple formats for automatic fallbacks:
<picture>
<source srcset="image.avif" type="image/avif">
<source srcset="image.webp" type="image/webp">
<img src="image.jpg" alt="Description">
</picture>Browsers automatically select the best format they support, falling back to JPEG for older browsers.
Use a CDN with Auto-Conversion
Modern CDNs like Cloudflare, Fastly, and Cloudinary can automatically convert and serve AVIF:
- • Cloudflare: Enable "Polish" and "WebP/AVIF" in dashboard
- • Cloudinary: Add
f_autoto URLs - • imgix: Add
auto=formatparameter - • AWS CloudFront: Use Lambda@Edge for dynamic conversion

Frequently Asked Questions
Is AVIF better than WebP for websites?

Will AVIF images slow down my website?
No, AVIF images load faster than JPEG/PNG due to smaller file sizes. However, decoding can be slightly slower on older devices. Always provide JPEG fallbacks and test performance on your target devices.
