Convert JPG to AVIF Online — Next-Gen Compression

AVIF is the next-generation successor to JPEG. Based on the AV1 video codec, AVIF achieves 40-60% smaller file sizes compared to JPEG at equivalent visual quality, resulting in:

• Superior compression: Better than WebP and far better than JPEG
• Excellent detail retention: Preserves fine textures even at high compression
• Faster page loads: Smaller files = faster downloads on all networks
• Lower bandwidth costs: Reduced data transfer for you and your users
• Wide browser support: 92% global support (Chrome 85+, Firefox 93+, Safari 16.4+)

Yes, with fallback. AVIF is supported by 92% of global browsers as of 2025:

• Chrome: 85+ (September 2020)
• Firefox: 93+ (October 2021)
• Safari: 16.4+ (March 2023) — macOS 13+ and iOS 16.4+
• Edge: 121+ (January 2024)

Not supported: Internet Explorer, Safari 15 and earlier, older Android browsers. Always use the <picture> element with WebP or JPEG fallback for production. Need broader browser support without fallback complexity? Try JPG to WebP for 97% compatibility and 25-35% file size reduction.

JPG to AVIF conversion typically achieves 40-60% file size reduction with quality 75 encoding (visually equivalent to JPEG Q90-95).

Examples:

• 1 MB JPEG photo → 400-600 KB AVIF (40-60% reduction)
• 5 MB JPEG portrait → 2.0-3.0 MB AVIF (40-60% reduction)
• 500 KB JPEG product shot → 200-300 KB AVIF (40-60% reduction)

AVIF excels at preserving fine detail even at high compression. Complex textures (foliage, fabric) compress slightly better than smooth gradients (sky, skin tones).

Minimal loss for single conversion. AVIF Q75 is visually equivalent to JPEG Q90-95 in perceptual quality tests. For web delivery (social media, e-commerce, blogs), the output is indistinguishable from the JPEG original.

Important: Like all lossy formats, avoid repeated re-encoding (JPEG → AVIF → JPEG → AVIF). Each conversion introduces generation loss. Always keep your high-quality originals and convert from the source.

For archival or editing workflows where lossless quality is required, use PNG or lossless WebP instead.

Use the HTML <picture> element to provide multiple formats. The browser automatically selects the first supported format:

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

How it works: Modern browsers load the smaller AVIF. Safari 15 and older fallback to WebP. IE and legacy browsers fallback to JPEG. This ensures maximum compression with universal compatibility.

Format comparison:

• AVIF: Best compression (40-60% smaller than JPG). Use for modern web delivery with <picture> fallback. Ideal for bandwidth-sensitive applications.
• WebP: Good compression (25-35% smaller than JPG), 93% browser support. Best balance of compression and compatibility without fallback.
• JPG: Universal compatibility (100%), but largest file sizes. Use as final fallback or when compatibility is critical (email, PDF, legacy systems).

Recommendation: Use AVIF + WebP + JPG with <picture> for optimal delivery. If fallback is too complex, try our JPG to WebP converter for the best balance of compression and compatibility without fallback.
