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.
JXL browser support trails WebP's ubiquity. Serve WebP today from JXL masters, keep JXL archived for the future.
WebP runs ~20–30% larger than JXL at equal quality — still far smaller than JPEG. Acceptable bridge cost.
85 for photos preserves JXL fidelity visibly; 75 for thumbnails. One batch per use-case.
No — conversion runs locally in your browser on Canvas. Only saves touch the network — downloads are unlimited.
WEBP to JXL
WEBP to JXL output is not produced here — Canvas cannot encode JXL, so conversion fails locally. Convert WEBP to JPG or PNG instead — local, unlimited saves.
Bulk Image Format Converter
Convert image batches between JPG, PNG, WebP, and AVIF outputs (JPEG/PNG/WebP/AVIF/HEIC/HEIF/GIF/BMP/ICO/SVG inputs; HEIC via heic2any, SVG rasterized at intrinsic size or 1024px fallback) with a quality slider (10–100, default 80). Pair pages (?from/?to) preset the output. Flat ZIP renamed per file — local, 5-file guest batches, 25 signed-in, 500 Pro.
Image Format Converter
Convert one browser-decodable image to PNG, JPG, or WebP — the only outputs canvas can encode. HEIC/SVG/JXL/TIFF and other exotic targets fail honestly instead of pretending. Nothing is uploaded; every conversion runs in your browser.
