Compress AVIF Files
AVIF is the newest and most efficient image format available, offering 20-50% smaller files than WebP at equivalent quality. But AVIF files exported from editors or converted from high-resolution originals can still benefit from quality tuning. Pixotter compresses AVIF files in your browser — no upload, no server processing, instant results.
When to Compress AVIF
- Web performance — AVIF is already efficient, but quality tuning can save an extra 20-40% on file size
- Image-heavy sites — Galleries, portfolios, and e-commerce sites benefit most from AVIF compression
- Progressive enhancement — Serve optimized AVIF to supported browsers with JPEG/WebP fallbacks
- Storage optimization — Compress AVIF archives and backups to save disk space
AVIF Browser Support
AVIF is supported in Chrome, Firefox, Safari 16+, and Edge. For older browsers or platforms that don't support AVIF, consider converting to WebP (next best compression) or converting to JPEG (universal compatibility). Most modern websites serve AVIF as the primary format with WebP and JPEG fallbacks.
How It Works
Drag and drop one or more AVIF images. Batch processing handles up to 20 files at once.
Use the quality slider to find the perfect balance. AVIF retains excellent quality even at low settings.
Download individual files or grab them all as a ZIP. The before/after slider shows the quality difference.
