Technical Details
AV1 Codec Foundation
AVIF is built on the AV1 video codec, utilizing advanced intra-frame compression techniques originally designed for video. This provides superior compression efficiency through better prediction algorithms, transform coding, and entropy coding compared to JPEG’s DCT-based approach.
Advanced Color Science
While JPEG is limited to 8-bit YUV 4:2:0 color sampling, AVIF supports up to 12-bit color depth with 4:4:4 chroma sampling. This enables better color accuracy, reduced banding, and support for HDR content with wider color gamuts like Rec. 2020.
Container Structure
AVIF uses the ISO Base Media File Format (ISOBMFF) container, allowing for metadata storage, multiple image sequences, and auxiliary image data. This provides more flexibility than JPEG’s simple structure while maintaining efficient random access to image data.

Frequently Asked Questions
What quality settings should I use when converting JPEG to AVIF?
For most images, an AVIF quality setting of 50-60 provides similar visual quality to JPEG at 85-90 quality but with 50-70% smaller file sizes. For photographs, quality 60-70 preserves fine details excellently while achieving significant compression gains.
Will converting JPEG to AVIF improve image quality?
Converting JPEG to AVIF won’t recover quality lost in the original JPEG compression, but AVIF’s superior algorithms often preserve existing quality better at smaller file sizes. You may see reduced compression artifacts and better color gradients in the AVIF version.
Which browsers and devices support AVIF format?
AVIF is supported by Chrome 85+, Firefox 93+, Safari 16+, and Edge 121+. Mobile support includes Android 12+ and iOS 16+. While growing rapidly, consider providing JPEG fallbacks for older browsers.
How much smaller will my JPEG files become as AVIF?
AVIF typically achieves 50-90% smaller file sizes compared to equivalent quality JPEG images. Photographs with complex details see 50-70% reduction, while graphics and images with large uniform areas can achieve up to 90% size reduction.
Can AVIF handle transparency that JPEG cannot?
Yes, AVIF natively supports alpha channel transparency, making it an excellent replacement for PNG images as well. When converting JPEG to AVIF, no transparency is added, but the format capability is available for future editing.
Should I keep my original JPEG files after converting to AVIF?
It’s recommended to keep original JPEG files as master copies since AVIF browser support is still growing. Many websites serve AVIF to supported browsers with JPEG fallbacks for compatibility.
Does AVIF support the same metadata as JPEG files?
AVIF supports metadata storage including EXIF data, color profiles, and other image information from JPEG files. The conversion process can preserve camera settings, GPS coordinates, and other metadata embedded in your original JPEG images.
Is AVIF suitable for print materials like JPEG?
While AVIF offers superior quality and color depth capabilities, JPEG remains more universally supported for print workflows. AVIF is primarily optimized for digital display, though its enhanced color support makes it excellent for high-quality digital viewing before print conversion.
