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.
| uncompressed | gzip -9 | brotli -9 | |
