WebP is a modern image format built for the web: at the same visual quality, it typically produces files 25-35% smaller than JPG and up to 80% smaller than PNG. Smaller images mean a faster-loading page, which directly helps Core Web Vitals metrics like Largest Contentful Paint - a factor search engines like Google use when ranking pages.
Export a PNG or JPG from Figma, Sketch, Adobe XD or Illustrator, then convert and compress it here - transparent backgrounds on icons and logos stay clean instead of picking up the white or black fringing that some converters introduce around edges. The Alpha quality slider under Advanced settings gives you direct control over how sharply that transparency compresses, and Sharp YUV keeps hard edges - icon outlines, wordmarks, flat UI graphics - crisp instead of soft. The result is a lighter asset for your app icon set, favicon, or website UI without a visible quality hit.
Yes. WebP fully supports alpha transparency like PNG. Use the Alpha quality slider in Advanced settings to control how sharply transparent edges - like icon and logo outlines - get compressed.
No. Conversion runs 100% locally in your browser using WebAssembly - the same libwebp encoder used by native apps. Your image never leaves your device.
Lossy (the Quality slider) gives the smallest file size and is usually indistinguishable from the original for icons and photos alike. Lossless (the Lossless toggle) is pixel-perfect but produces a larger file - reach for it only when exact fidelity matters, e.g. pixel art or flat, solid-color icons.
Yes - this tool is built with icons and logos in mind. Export a PNG or JPG from Figma, Sketch, Adobe XD or Illustrator, then convert and compress it here without losing transparency or crispness.
Not if you keep quality above roughly 80, or turn on Sharp YUV in Advanced settings to keep hard edges like icon outlines and text crisp. A lower filter strength also helps preserve fine detail.
