Convert JPG photos to modern AVIF. Up to 50% better compression than JPG while maintaining quality. Runs entirely in your browser. No server uploads, no registration required.

JPG has been the standard photo format for decades, but AVIF (AV1 Image File Format) delivers 30–50% better compression at equivalent visual quality. AVIF is based on the AV1 video codec and excels at preserving fine details and smooth gradients even at very low file sizes.
AVIF supports millions of colors, alpha transparency, HDR content, and both lossy and lossless modes. It is supported in Chrome 85+, Firefox 93+, Safari 16.4+, and Edge 121+. Converting JPG to AVIF is one of the most impactful optimizations for website performance.
Google PageSpeed Insights specifically recommends serving images in next-gen formats like AVIF. Use the HTML <picture> element to serve AVIF with JPG as a fallback for older browsers.
All processing happens locally in your browser — nothing is sent to any server. No registration, no limits, no watermarks.
Businesses, developers, and creators worldwide rely on image format compatibility. Whether you are preparing product images for Amazon, eBay, Etsy, Shopify, optimizing graphics for WordPress, Wix, Squarespace, or converting photos for government portals worldwide, having the right format matters.
Modern web standards increasingly favor efficient formats. Google PageSpeed Insights and Core Web Vitals metrics reward pages that use optimized images. Converting JPG to AVIF can directly improve your Largest Contentful Paint (LCP) score, which impacts both search rankings and user experience.
For email marketing campaigns and social media, AVIF provides excellent compression while maintaining visual quality. Whether you are a freelancer, small business owner, or enterprise user, this converter handles your image conversion needs reliably and securely.

The quality slider lets you set a value from 60% to 95%. Higher values mean better image quality but larger file sizes.
At 80% quality, AVIF typically produces files 30–50% smaller than the original JPG while maintaining visual quality indistinguishable to the human eye.
Savings depend on the original JPG’s compression level. Below are example results:
Camera photo
2.4 MB → 650 KB
Product image
500 KB → 150 KB
Screenshot / banner
350 KB → 120 KB
Actual savings vary depending on image content and quality settings. The converter shows the exact size before and after conversion for each file.
