Why Use This Tool?
AVIF is the new king of image compression — smaller files than WebP at the same quality. Drop your JPGs here and the tool encodes AVIF whenever your browser supports it, falling back to WebP automatically when it doesn't.
Either way you get a modern, much lighter file. The result card tells you exactly which format you downloaded, so there are no surprises.
How It Works
- Drop your JPG files — batches are welcome.
- Set your quality. AVIF shines at lower settings, so 70 is a great start.
- Download AVIF files, or WebP with a clear fallback badge.
Frequently Asked Questions
Why the WebP fallback?
Browser support for encoding AVIF is still rolling out. When the browser can't produce AVIF, the tool downloads WebP instead — still dramatically smaller than JPG.
Is AVIF smaller than WebP?
Usually 20–30% smaller at the same quality. Where AVIF isn't available yet, WebP is the best browser-ready alternative.
Can I control the quality?
Yes — the quality slider applies to both AVIF output and the WebP fallback.
Tips & Things to Watch
- Try 60–70 first — AVIF tolerates lower quality gracefully.
- Check the badge to know which format you actually downloaded.
- Serve AVIF with a WebP fallback in production for full coverage.
