Why Convert JPG to AVIF?

AVIF represents a generational leap in image compression technology. Developed by the Alliance for Open Media using the AV1 video codec, AVIF achieves approximately 50% better compression than JPEG and 20-30% better than WebP at equivalent visual quality. For photographs, AVIF particularly excels at preserving skin tones, gradients, and fine textures that other formats struggle with at low bitrates. Major technology companies including Netflix, Google, Apple, and Meta have adopted AVIF for image delivery. Converting your JPEG library to AVIF can dramatically reduce bandwidth costs and improve page load times. With browser support now exceeding 93% and growing, AVIF is rapidly becoming the standard for next-generation web images.

JPG vs AVIF Comparison

JPEG was revolutionary when introduced in 1992 and remains the most widely used photo format. AVIF, standardized in 2019, uses far more advanced compression algorithms derived from AV1 video encoding. At the same visual quality, AVIF produces files roughly half the size of JPEG. AVIF additionally supports 10-bit and 12-bit color depth, HDR, alpha transparency, and both lossy and lossless modes, all of which JPEG lacks. JPEG has 100% compatibility everywhere while AVIF has 93% browser support with software adoption accelerating. The one downside of AVIF is slower encoding speed due to the complexity of AV1 compression. For web performance, AVIF is definitively superior. For maximum compatibility, JPEG with AVIF served as progressive enhancement is the optimal strategy.

Frequently Asked Questions

How much smaller is AVIF compared to JPG?▶
AVIF achieves approximately 50% better compression than JPEG at equivalent visual quality. A 1 MB JPEG photo might become 400-500 KB as AVIF with no perceptible quality difference. For web delivery, this translates to significantly faster page loads.
Is AVIF better than WebP for photographs?▶
Yes, AVIF generally outperforms WebP by 20-30% in file size at the same quality level, especially for photographs with gradients, skin tones, and fine textures. AVIF also handles low-contrast areas and subtle color transitions better than WebP.
Can all browsers display AVIF images?▶
AVIF is supported by Chrome 85+, Firefox 93+, Safari 16+, and Edge 85+. This covers approximately 93% of web users. For full compatibility, use the HTML picture element to serve AVIF with JPEG or WebP fallbacks for older browsers.
Is JPG to AVIF conversion slow?▶
AVIF encoding is computationally intensive compared to JPEG or WebP because the AV1 codec uses advanced algorithms. However, our dedicated AVIF converter runs entirely in your browser using optimized WebAssembly, making it practical for batch conversion without uploads.
