JPEG XL 技术精湛，但实际上却被束之高阁——Chrome 浏览器在 2022 年停止了对它的原生支持，而且相关工具的普及率也很低。JPEG 文件几乎可以在任何地方打开。将 JXL 文件转换为 JPEG 格式，即可达到 JPEG 文件 100% 的覆盖率。

支持JPG, JPEG, PNG, WEBP, SVG, GIF, HEIC, HEIF, BMP, TIFF, HDR, JP2, RAF, PSD, CR3, DNG, APNG, AVIF, AVI, ESP, EXR, J2C, J2K, JXL, PFM, PNM, PPM, PSB, SGI, MPEG, PDF
支持所有 .jxl 文件——无论是有损格式、无损格式还是 JPEG 转码格式。libjxl 参考解码器可以处理所有 JXL 变体。
JXL 在浏览器中解码为原始像素。这些像素以质量 90 编码为 JPEG。对于无损转码的 JPEG JXL，原始 JPEG 比特流可能可以恢复。
标准 JPEG 输出可在 1995 年以来的所有应用程序中打开。嵌入 ICC 配置文件，保留 JXL 源中的 EXIF 元数据。

Note, JPEG is a lossy compression. In addition, you cannot create black and white images with JPEG nor can you save transparency. Requires jpegsrc.v8c.tar.gz. You can set quality scaling for luminance and chrominance separately (e.g. -quality 90,70). You can optionally define the DCT method, for example to specify the float method, use -define jpeg:dct-method=float. By default we compute optimal Huffman coding tables. Specify -define jpeg:optimize-coding=false to use the default Huffman tables. Two other options include -define jpeg:block-smoothing and -define jpeg:fancy-upsampling. Set the sampling factor with -define jpeg:sampling-factor. You can size the image with jpeg:size, for example -define jpeg:size=128x128. To restrict the maximum file size, use jpeg:extent, for example -define jpeg:extent=400KB. To define one or more custom quantization tables, use -define jpeg:q-table=filename. These values are multiplied by -quality argument divided by 100.0. To avoid reading a particular associated image profile, use -define profile:skip=name (e.g. profile:skip=ICC).
