- Alpha channel support (transparency) - something JPG can't do
- Better Core Web Vitals - smaller images mean faster LCP (Largest Contentful Paint)
Every major browser now supports WebP: Chrome, Firefox, Safari, Edge, and Opera. There's no reason not to use it in 2026.

Best Quality Settings for JPG to WebP
- Quality 75-80: Best for most web images. Virtually indistinguishable from the original.
- Quality 85-90: For photography portfolios or when detail matters.
- Quality 50-70: For thumbnails, previews, or background images.
- Lossless: When you need pixel-perfect conversion (usually larger than JPG).
Our recommendation: start at 80% and adjust down until you notice quality loss. Most people can't tell the difference between 75% and 95% WebP.
