Convert JPG to AVIF

AVIF is the newest generation of image compression, built on the AV1 video codec. It achieves file sizes that are 40–50% smaller than equivalent JPEG images while maintaining or even improving perceptual quality — making it the most efficient format available for photographic content today.

Converting your JPGs to AVIF delivers real-world performance gains. A typical product photo at 1,200 pixels wide might weigh 120 KB as a JPEG and just 65 KB as an AVIF at the same visual quality. That halved file size translates directly into faster Largest Contentful Paint (LCP) times, which is one of Google's Core Web Vitals metrics used in search ranking. Faster pages also reduce bounce rates, which means more engaged visitors.

Browser support for AVIF has matured rapidly. Chrome, Firefox, and Safari on Apple platforms all support AVIF natively. The main caveat is that encoding AVIF is computationally more intensive than WebP. OptiPic uses your browser's native encoding capabilities, so encoding times may be slightly longer than for WebP, but the results are worth it for images that will be served repeatedly to many users.

One particularly powerful use case is converting high-resolution photographs — camera shots, professional product images, editorial photography — to AVIF. The codec is especially effective on complex, natural imagery with many gradients, which is exactly where traditional JPEG compression tends to show blocky artefacts first.

For compatibility-sensitive projects, consider using AVIF as your primary format with a JPEG fallback via the HTML <picture> element. This way, AVIF-capable browsers get the optimal file, and older browsers fall back gracefully. Converting your image library to AVIF now future-proofs your assets for the web.
