Why convert JPG to AVIF?
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.

- 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.
