Why Convert JPEG to AVIF?
AVIF achieves up to 50% better compression than JPEG at equivalent visual quality. Converting your JPEG library to AVIF can dramatically reduce storage and bandwidth costs.
Common Use Cases
- Modernizing image libraries for the web
- Maximum compression for photograph-heavy sites
- Improving page load speed and Core Web Vitals
- CDN cost optimization
Source Format
JPEG
Joint Photographic Experts Group
JPEG is the most widely used lossy image format, optimized for photographs and complex images with smooth color transitions. It achieves excellent compression ratios at the cost of some quality loss.
+ Excellent compression for photographs
+ Universally supported everywhere
+ Adjustable quality-to-size ratio
- Lossy compression degrades quality with each save
- No transparency support
Target Format
AVIF
AV1 Image File Format
AVIF is a next-generation image format based on the AV1 video codec. It offers significantly better compression than JPEG and WebP while maintaining high visual quality, transparency, and animation support.
+ 50% smaller than JPEG at equivalent quality
+ Better compression than WebP
+ Supports transparency, animation, and HDR
- Slower encoding and decoding than JPEG or WebP
- Limited support in older browsers and software
Quality & Size Notes
AVIF handles photographs exceptionally well. Quality 50-70 in AVIF often looks comparable to JPEG quality 80-90 at a fraction of the file size. Encoding is slower than JPEG.
Frequently Asked Questions
How much smaller is AVIF than JPEG?
AVIF is typically 40-50% smaller than JPEG at equivalent visual quality. A 500KB JPEG might be 250-300KB as AVIF with no visible difference.
Is AVIF better than WebP for photos?
Yes, AVIF generally achieves 20-30% better compression than WebP for photographs, though encoding is slower.
What AVIF quality setting should I use?
For photographs, quality 50-70 produces excellent results. AVIF is much more efficient than JPEG, so lower numbers still look great.
