JPG to AVIF converter
Convert JPG/JPEG to AVIF online. Requires browser AVIF encoding support.
Overview
Hand off JPEGs into AVIF for modern delivery stacks. The JPEG is decoded and re-encoded, so you do not regain lost detail, but file size may drop. If the browser cannot encode AVIF, use PNG/JPEG/WebP converters here instead.
Converting JPG → AVIF. Processing stays in your browser.
Frequently asked questions
Why convert JPG to AVIF instead of keeping JPEG for the web?
AVIF often beats JPEG on size at similar perceived quality when the encoder is available.
Why does JPG to AVIF conversion fail, and how can I fix it?
Try a Chromium-based browser with current AVIF encode support, or export WEBP/PNG instead.
Is JPG to AVIF private—are images uploaded?
No. Everything runs locally in the tab.
