AVIF is the dominant web format in 2026 but many apps still can't open it — email clients, Lightroom legacy, older Windows tools. Converting to JPG makes your images work everywhere, instantly.
AVIF decoding uses the browser's built-in image engine. Your files never leave your device. No server, no cloud, no signup required.
Convert up to 20 AVIF files at once. Quality slider 50-100%. Choose white or black background for AVIF images with transparency.
AVIF (AV1 Image File Format) became the dominant web image format around 2024-2025. Chrome, Edge, Firefox and Safari all serve and download AVIF images by default. But many desktop apps, email clients, and older operating systems still can't open .avif files — including Windows Photo Viewer on older Windows versions, Adobe Lightroom Classic (pre-2024), Microsoft Office, and most email clients.
Converting AVIF to JPG gives you maximum compatibility: every app, every device, every operating system can open a JPG. The tradeoff is file size — JPG is typically 40-50% larger than AVIF at the same visual quality — but for sharing and compatibility purposes that is usually acceptable.
Modern browsers (Chrome 85+, Firefox 93+, Safari 16+) include a native AVIF decoder. omnikitbolt uses your browser's built-in decoder to render the AVIF image onto an HTML Canvas element, then exports the canvas as a JPEG. The entire process happens locally — no file is ever sent to a server.
AVIF supports an alpha channel (transparency). JPG does not. When an AVIF with transparency is converted, transparent pixels are filled with a solid color. omnikitbolt lets you choose white (default, best for most images) or black background. If you need to preserve transparency, convert to PNG instead.
