Convert WebP files to AVIF. Even better compression in a modern format. All processing happens locally in your browser - files never leave your device.

WebP and AVIF are both modern formats, but AVIF typically achieves 20–30% better compression than WebP at equivalent visual quality. AVIF is based on the AV1 video codec and excels particularly at low bitrates — where WebP may show visible artifacts, AVIF maintains clean details.
AVIF is supported in Chrome 85+, Firefox 93+, Safari 16.4+, and Edge 121+. If you already serve WebP images and want even smaller files, converting to AVIF is the next optimization step. Use the HTML <picture> element to serve AVIF with WebP as a fallback.
AVIF encoding is more computationally intensive than WebP, so conversion may take slightly longer for large images. The resulting files, however, are significantly smaller.
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 WebP 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.
AVIF encoding is more computationally intensive than WebP, so conversion may take slightly longer. The result, however, is a smaller file with comparable or better visual quality.
AVIF typically achieves 20–30% better compression than WebP. Example comparisons:
Camera photo
WebP: 240 KB → AVIF: 180 KB
Product image
WebP: 115 KB → AVIF: 85 KB
Screenshot
WebP: 160 KB → AVIF: 120 KB
Savings are most pronounced at lower bitrates. For very high quality settings (90%+), the difference between WebP and AVIF narrows.
