WebP is Google's modern image format, supported in all major browsers since 2020. It offers roughly 30% better compression than JPEG and supports both lossy and lossless modes, animation, and alpha transparency. While JPEG XL is technically superior to WebP — achieving 20-30% better compression and supporting HDR, wider gamuts, and progressive decoding — WebP has the critical advantage of near-universal browser support that JXL currently lacks.
Converting JXL to WebP is the practical choice for web publishing today. Google Chrome, Firefox, Safari, Edge, and all Chromium-based browsers render WebP natively. Content delivery networks and image optimization services widely support WebP. If you have adopted JXL for its storage efficiency and need web-compatible output, WebP provides the closest modern alternative with the broadest browser support.
The web needs images that every visitor can see. JPEG XL has been removed from Chrome and has only experimental support in Firefox, meaning the majority of web traffic cannot view JXL images. WebP fills the gap as the most widely supported modern image format — it is natively rendered by browsers representing over 96% of global web traffic.
WebP also outperforms JPEG in both lossy and lossless modes, making it a significant upgrade even when the original JXL provided even better compression. For websites optimizing Core Web Vitals and page load speed, WebP delivers meaningful file size reductions over JPEG while maintaining broad compatibility. Major platforms including WordPress, Shopify, and Cloudflare automatically serve WebP variants.
The converter decodes the JXL image and re-encodes it using libwebp. For lossy mode, WebP uses VP8-based compression with configurable quality (default 80). For lossless mode, WebP uses its own lossless coding scheme. Alpha transparency from the JXL source is preserved in both lossy and lossless WebP modes. EXIF metadata is transferred to the WebP output. Animated JXL sequences are converted to animated WebP with frame timing preserved.
At quality 80, lossy WebP produces visually excellent results that are difficult to distinguish from the source. Quality 90+ approaches transparency for most photographic content. Lossless WebP preserves every pixel exactly but produces larger files. WebP's compression is roughly 30% more efficient than JPEG but 20-30% less efficient than JXL for equivalent visual quality.
