JXL
JPEG XL
A next-generation image codec offering both lossless and lossy compression with progressive decoding and HDR support.
Detalle técnico
File jxl reduces storage and transmission size. DEFLATE (used in ZIP and gzip) combines LZ77 dictionary coding with Huffman coding. Brotli (RFC 7932) achieves 15-25% better compression than gzip for text content and is supported by all modern browsers for HTTP compression. Zstandard (zstd) offers tunable compression levels from fast (comparable to lz4) to high (comparable to LZMA). For files already in compressed formats (JPEG, MP3, ZIP), re-compression provides negligible benefit and may slightly increase file size.
Ejemplo
```javascript
// Create ZIP archive in browser (using JSZip)
const zip = new JSZip();
zip.file('readme.txt', 'Hello World');
zip.file('data/report.csv', csvContent);
const blob = await zip.generateAsync({
type: 'blob',
compression: 'DEFLATE',
compressionOptions: { level: 6 },
});
saveAs(blob, 'archive.zip');
```
