Convert AVIF images to high-quality JPEG instantly — 100% in your browser. No uploads, no servers, complete privacy.
AVIF (AV1 Image File Format) is a modern image format derived from the AV1 video codec. It offers 20–50% better compression than JPEG at the same quality, supports HDR, wide color gamut, and transparency (alpha channel).
JPEG enjoys near-universal compatibility — every device, app and platform supports it. Converting AVIF to JPG ensures images display correctly in older browsers, email clients, social media, and printing workflows that don't support AVIF yet.
This tool uses the HTML5 Canvas API. The AVIF file is decoded by the browser's native image decoder into a bitmap, drawn onto a canvas with the selected background color, then re-encoded to JPEG via canvas.toDataURL('image/jpeg', quality).
Quality 92 is the default — visually near-lossless while keeping file sizes reasonable. For web use, quality 80 offers a great size/quality balance. Quality 100 produces the largest file with no additional visible benefit beyond ~95 in most cases.
