d8code

Encode binary data as a UTF-8 string that may compress efficiently.

It may be an interesting alternative to base64 and hex encoding to inline WebAssembly code in a Javascript module.

wasm-crypto

wasm-crypto mainly contains code. The data section is small.

| | uncompressed | gzip -9 | brotli -9 | | --------------------- | ------------ | ------- | --------- | | non encoded | 230204 | 66807 | 56528 | | base64 encoded | 306941 | 78534 | 72305 | | hex encoded | 460408 | 73352 | 70044 | | d8 encoded | 278523 | 72009 | 65816 | | d8 encoded, pshift=35 | 268758 | 71737 | 65212 |

libsodium

libsodium mainly contains optimized code. The data section is small.

| | uncompressed | gzip -9 | brotli -9 | | -------------- | ------------ | ------- | --------- | | original | 142651 | 73847 | 67085 | | base64 encoded | 190205 | 91460 | 83944 | | hex encoded | 285302 | 84001 | 75940 | | d8 encoded | 183114 | 82821 | 71612 |

tanks

The Tanks game contains code, but also a solid amount of already compressed binary data.

Base64 encoding performs the best here, even though any kind of encoding should be avoided here.
