Frequently Asked Questions
Why convert JPEG XL to WebP?
JPEG XL (JPEG XL) uses lossy or lossless encoding and is best for next-gen image archival — better compression than JPEG with support for wide gamut and HDR. WebP (Web Picture Format) uses lossy or lossless encoding and excels at modern websites — Google-recommended format with superior compression for faster page loads. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
Why step down to WebP?
JXL browser support trails WebP's ubiquity. Serve WebP today from JXL masters, keep JXL archived for the future.
Size comparison?
WebP runs ~20–30% larger than JXL at equal quality — still far smaller than JPEG. Acceptable bridge cost.
Quality setting?
85 for photos preserves JXL fidelity visibly; 75 for thumbnails. One batch per use-case.
Do next-gen files upload?
No — conversion runs locally in your browser on Canvas. Only saves touch the network — downloads are unlimited.
