Compress AVIF
Re-encode AVIF assets to hit aggressive performance budgets on sites that already serve the format.

or click to browse — JPEG, PNG, WebP, GIF, AVIF, HEIC
AVIF can outperform WebP and JPEG on many photographic scenes, which is why performance-minded teams adopt it. This compressor tightens AVIF files that left design tools larger than your budget allows.
Encoding is computationally heavier than older formats; give the browser a moment on large photos. Always soft-proof brand colors—wide-gamut sources can surprise you after a tough quality setting.
Provide fallbacks (WebP/JPEG) for browsers without AVIF. If your asset is still JPEG, convert through your usual pipeline first, then compress the AVIF derivative here.
How to use
- Upload an AVIF image — Select a .avif file exported from your imaging pipeline.
- Choose a quality target — Start conservative; AVIF often remains small even at higher visual quality.
- Preview carefully — Check gradients and fine text for smearing unique to modern codecs.
- Download the optimized AVIF — Replace the heavy asset in your CDN or static folder.
- Verify fallbacks — Confirm <picture> or CDN rules still serve WebP/JPEG where AVIF is unsupported.
Use cases
- Next-gen hero images — Keep large landing visuals sharp under tight transfer budgets.
- Commerce galleries — Ship multiple product angles without blowing the network waterline.
- Performance audits — Respond to Lighthouse image opportunities with a smaller AVIF pass.
Tips
- Always keep a widely supported fallback format in production.
- Encode from high-quality masters; do not AVIF-crush a tiny JPEG twice removed.
- Test Safari/Chrome/Firefox versions you actually support.
- If AVIF encode fails on a device, fall back to WebP compression workflows.
FAQ
Support is broad on modern browsers but not universal. Keep fallbacks.
Intended to run in the browser; large images may take longer to encode.
This page prioritizes web-sized lossy delivery. Preview any lossless experiments carefully.
Use your conversion pipeline first if this tool expects AVIF input; then compress.
AVIF is heavier than JPEG encode. Smaller dimensions finish faster.
compress-webp and jpg-to-webp remain strong alternatives for broader support.
