Why convert JXL to WebP?

JXL (JPEG XL) — Official JPEG successor. Superior compression, performant lossless mode, and reversible conversion from existing JPG files.

WebP (WebP (Google)) — Modern format from Google, roughly 25–35% lighter than JPG for equivalent quality. Supports transparency, animation, and both lossy and lossless modes.

Converting JXL to WebP typically reduces file size while preserving a visual quality close to the original.
