Frequently Asked Questions

How much smaller is AVIF compared to JPEG?

At equivalent perceived quality, AVIF files are typically 40-60% smaller than JPEG. A 500KB JPEG photo often converts to a 200-300KB AVIF with no visible quality difference at normal viewing sizes.

Is AVIF supported on all browsers?

AVIF is supported in Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+. As of 2025, these browsers cover over 95% of global web traffic. For the remaining 5%, serve JPEG as a fallback using the HTML picture element.

What quality setting should I use for AVIF?

Quality 60 (the default) is a good starting point for web images — it produces files that look sharp at normal screen sizes while keeping file sizes small. For high-fidelity product photos or print-preview images, use 75-85.
