AVIF vs JPEG: The 2026 Guide
JPEG has been the world's default photo format for decades. AVIF is the modern challenger, and it wins on file size by a large margin.
If you run a website, the choice matters: AVIF can cut your image bandwidth in half without a visible quality difference.
Size: AVIF is typically 30–50% smaller
AVIF (AV1 Image File Format) uses modern video-derived compression. At the same visual quality, an AVIF photo is usually 30–50% smaller than a JPEG. On image-heavy pages that can mean seconds saved on load time.
Quality: equal or better at lower bitrates
AVIF produces fewer artifacts than JPEG at the same file size, especially around text and sharp edges. It also supports HDR and wide color gamut, which JPEG cannot.
Support: all modern browsers
Chrome, Firefox, Safari, and Edge all support AVIF. The main gap is older software and some tools that still handle only JPEG. The standard solution is to serve AVIF with a JPEG fallback using the HTML picture element — modern browsers get the small file, older ones get a compatible one.
When to stick with JPEG
JPEG is still the right choice when you need maximum compatibility: email attachments, print workflows, legacy systems, and anything that must open everywhere without exception.
For web images in 2026, AVIF is the better format — smaller and equal quality. Keep JPEG for maximum compatibility. Try converting a JPEG to AVIF and compare the sizes yourself to see the difference on your own photos.
