Convert any JPG or JPEG file to AVIF online for free. Upload your image and download an AVIF in seconds. Works in Chrome 101+ and Firefox 113+. No signup, no software, no watermarks.
AVIF is the most efficient image format currently available for web delivery. At the same perceived quality level, AVIF produces files 30 to 50 percent smaller than JPG and 20 to 30 percent smaller than WebP. Converting to AVIF is one of the most effective ways to reduce image payload on a website while maintaining high visual quality.
Note: AVIF output requires Chrome 101+ or Firefox 113+, which include a built-in AVIF encoder. If you are using Safari, switch to Chrome or Firefox to use this conversion.
AVIF is the next step beyond WebP for web image delivery — smaller files, higher quality, with growing browser support.
AVIF is now supported by Chrome, Firefox, Edge and Safari (for display). Sites that serve AVIF can reduce their image payload by 30 to 50 percent compared to JPG, directly improving Largest Contentful Paint (LCP) scores — one of the three Core Web Vitals that Google uses as ranking signals. For performance-focused engineering teams, AVIF conversion is a high-impact optimisation.
Product image galleries are often the heaviest part of an e-commerce page. Converting product photography from JPG to AVIF reduces the per-page image payload dramatically. For sites serving millions of page views, the bandwidth savings are substantial. Most major CDN providers now support AVIF delivery alongside WebP fallbacks.
News sites, magazines and content platforms serve dozens of images per article. Converting article photography to AVIF reduces page weight, speeds up initial render and improves the reading experience on mobile connections. The quality difference is negligible at typical article display sizes while the file size reduction is significant.
Quick answers about how this tool works and how to get the best results.
AVIF output relies on a built-in encoder included with the browser. Chrome and Firefox both include AVIF encoders. Safari supports AVIF for viewing but does not yet include an AVIF encoder — use Chrome or Firefox to create AVIF files.
Compared to JPG at the same visual quality, AVIF is typically 30 to 50 percent smaller. The exact saving depends on the image content — photographs with smooth gradients and varied tones see the greatest gains. At quality 60 in AVIF you can often match the visual quality of JPG at quality 85 while producing a smaller file.
Chrome, Firefox, Edge and Safari 16+ all display AVIF natively — covering over 90% of global browser traffic. For the remaining users, you should serve a WebP or JPG fallback using the HTML picture element. Most modern image delivery CDNs handle this automatically through content negotiation.
Yes. Conversion runs in your browser. Your JPG is never sent to a server. Close the tab and the data is cleared from memory.
