Frequently asked questions
Will the AVIF look better than the original JPG?
At the same file size, AVIF typically looks better. At the same quality setting, AVIF is much smaller. You can achieve visually equivalent images at roughly half the file size.
Can I use AVIF images on my website right now?
Yes, with a fallback. Use the HTML picture element to serve AVIF to supported browsers and JPG or WebP to others: <picture><source type='image/avif' srcset='image.avif'><img src='image.jpg'></picture>
How long does AVIF conversion take?
AVIF encoding is computationally intensive. Conversion typically takes 2-10 seconds depending on image size. This is a one-time cost - the resulting file serves faster on every subsequent load.
What is the main difference between JPG and AVIF?
JPG uses lossy compression with universal compatibility. AVIF achieves the smallest file sizes with both lossy and lossless modes, plus transparency and animation support.
