Do all modern browsers support AVIF?

Yes. Google Chrome, Apple Safari (iOS 16+ & macOS Ventura+), Mozilla Firefox, and Microsoft Edge all support AVIF natively.

Is my image uploaded to an external server?

No. Transcoding is performed directly in your browser using client-side image encoders.

How does AVIF compare to WebP?

AVIF typically achieves 15% to 20% smaller file sizes than WebP at equivalent visual fidelity, especially on high-contrast photographic textures.

What happens if a user's older browser doesn't support AVIF?

You can use the HTML5 element with an AVIF source and a WebP/JPG fallback so all browsers get the fastest supported format.
