JPG to AVIF converter

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.

• Start with quality 85 – this is typically the sweet spot for AVIF compression, offering significant file size reduction with minimal visible quality loss.
• Batch convert for efficiency – if you have many JPG files, use the batch conversion feature to process them all at once. This saves considerable time compared to one-by-one conversion.
• Compare before downloading – use the live preview to compare the original JPG with the AVIF result. Adjust quality settings until you find the right balance for your specific use case.
• Keep your originals – always save a copy of your original JPG files. Lossy compression is irreversible, so having the originals allows you to re-convert with different settings later.

The quality slider lets you set a value from 60% to 95%. Higher values mean better image quality but larger file sizes.

• 80% (default) – a good balance for most use cases: business websites, blogs, articles. The visual difference compared to the original JPG is virtually unnoticeable.
• 85–90% – for product photography, portfolios, and galleries where every detail matters.
• 60–70% – when minimizing file size is the priority, e.g. thumbnails in category grids.

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:
