JPG to AVIF — FAQ

Why convert JPG to AVIF?+
AVIF delivers 40–60% smaller files than JPEG at the same visual quality. Using AVIF reduces bandwidth costs, speeds up page loads, and improves Core Web Vitals.
Is AVIF widely supported?+
AVIF has 93%+ global browser support — Chrome 85+, Firefox 93+, Safari 16+, Edge 121+. Use a <picture> tag with a JPG fallback for older browser compatibility.
Will my photos lose quality when converting JPG to AVIF?+
At quality 80 (our default), the visual difference from the JPG source is imperceptible. AVIF's advanced codec produces cleaner results than JPEG at equivalent quality.
Does AVIF support transparency?+
Yes, AVIF supports full alpha transparency — but JPG does not. When converting JPG to AVIF, the result has no transparency since the source had none.
Is JPG to AVIF conversion worth it?+
Yes, if file size matters. AVIF typically reduces file size by 50%+ versus JPG at equivalent visual quality — ideal for website images. Modern browsers support AVIF natively. Picovert converts locally in your browser with no upload required.
Is AVIF better than WebP for web use?+
Generally yes — AVIF provides 20–30% better compression than WebP at the same perceptual quality. However, AVIF encoding is slower and browser support is slightly lower (90% vs 96% for WebP). For maximum compatibility, WebP is safer; for maximum compression, AVIF wins.
