About GZip, Deflate & Brotli Compression

GZip, Deflate and Deflate-raw use the native browser CompressionStream / DecompressionStream Web APIs. Browsers have no native Brotli in JavaScript, so Brotli runs through a local WebAssembly build — still fully client-side, no CDN.

No network requests: Your data is processed entirely in local memory.
