WebP for Websites: When to Use It (and When JPG Still Wins)

WebP was designed to cut page weight without a visible quality hit. For photographs, lossy WebP is often 25–35% smaller than a comparable JPG. For graphics with transparency, lossless WebP can replace bulky PNGs while keeping sharp edges.

Use WebP when you control the website stack and your audience is on modern browsers—which is nearly everyone in 2026. Pair it with sensible dimensions and lazy loading for the best Largest Contentful Paint scores.

Keep JPG when maximum compatibility matters: print labs, older email clients, or partners who cannot open WebP. Keep PNG when you need lossless editing headroom or simple transparency workflows in design tools that still prefer PNG.

Convert existing assets with PixelsKits Convert and Compress tools, then A/B check sharpness at 75–80% quality. Because conversion is local, you can iterate quickly without uploading your media library to a third party.
