AVIF vs WebP vs JPG — Which Image Format Should You Use?

The Quick Answer

• JPG: Universal compatibility. Use when you need to work everywhere (email, print, old software).
• WebP: 25-50% smaller than JPG. Use for websites, blogs, and anywhere modern browsers are guaranteed.
• AVIF: 50-70% smaller than JPG. Use for maximum optimization on modern platforms.

File Size Comparison

Same photo at equivalent visual quality:

• JPG: 500 KB (baseline)
• WebP: 300 KB (40% smaller)
• AVIF: 175 KB (65% smaller)

AVIF's advantage is dramatic. A website serving 20 images saves megabytes per page load by switching from JPG to AVIF.

Browser Support (2026)

• JPG: 100% — every device, every browser, ever.
• WebP: 97%+ — all modern browsers including Safari since 2020.
• AVIF: 93% — Chrome, Firefox, Opera, Samsung, Edge, Safari 16+.

The Best Strategy: Serve All Three

Modern websites serve the best format each browser supports:

<picture>
  <source srcset="photo.avif" type="image/avif">
  <source srcset="photo.webp" type="image/webp">
  <img src="photo.jpg" alt="Photo">
</picture>

Frequently Asked Questions

Is AVIF better than WebP?

For file size, yes — AVIF produces 20-30% smaller files than WebP at the same quality. But AVIF encodes slower and has slightly less browser support (93% vs 97%). Both are dramatically better than JPG.

Should I use AVIF on my website now?

Yes, with fallbacks. Serve AVIF first, then WebP, then JPG as the final fallback. This gives the smallest files to browsers that support it while still working everywhere.

Yes. Use our JPG to AVIF or PNG to AVIF converters. Free, no upload, instant conversion in your browser.
