JPG to AVIF — Free Online Maximum Compression Converter
Convert JPG to AVIF for superior compression — smaller files with better quality, ideal for performance-focused sites that can provide format fallbacks. Local processing, no upload.
AVIF is based on the AV1 codec and is typically far smaller than JPG at the same visual quality. It also supports HDR and wide colour gamut, making it a strong choice for web performance. Note: AVIF compatibility is still maturing — older browsers do not support it, so a JPG/WebP fallback is recommended. Some browsers also do not yet support AVIF encoding; this tool will show a clear status if that is the case.
Current Compatibility (Time-Sensitive)
As of 2025, Chrome, Edge, Firefox, and recent Safari all support displaying AVIF, but coverage is not yet as broad as WebP; older environments cannot display it. Compatibility data source: caniuse.com, recorded in 2025 — refer to the latest data for current figures.
Browser-side encoding support varies
In-browser AVIF encoding support is limited. This tool will give a clear status if your browser does not support it.
