As websites demand faster load times and richer visuals, legacy formats like JPG and PNG are being replaced by modern alternatives: WEBP and AVIF. Both offer superior compression and quality—but they’re not created equal.
Technical Comparison
Compression Efficiency
AVIF generally provides **20–30% smaller files** than WEBP at the same visual quality, thanks to its foundation in the AV1 video codec. For high-traffic sites, this can mean significant bandwidth savings.
Image Quality
AVIF supports 10-bit and 12-bit color depth, HDR, and wider color gamuts—ideal for premium photography or e-commerce. WEBP is limited to 8-bit but still outperforms JPG in most cases.
Transparency & Animation
Both support alpha transparency and animation. However, WEBP’s animation support is more mature and widely used (e.g., in Google products).
Browser Support in 2025
WEBP: Supported by **all major browsers** since 2020 (Chrome, Firefox, Edge, Safari 14+).
AVIF: Supported in Chrome, Firefox, and Edge—but **Safari only added full support in iOS 16 / macOS Ventura (2022)**. Older Apple devices still can’t display AVIF.
When to Use Which?
✅ Use WEBP if:
You need broad compatibility (including older iOS)
You’re optimizing a general-purpose website
You want a safe, proven upgrade from JPG/PNG
✅ Use AVIF if:
Your audience uses modern browsers
You prioritize maximum compression (e.g., image-heavy portfolios)
You work with HDR or wide-color content
