Smaller than base64, only use ASCII, can run in web browser.

Setup

npm i base128-ascii

import base128 from "base128-ascii"

const encodedTemplate = base128.encode(Uint8Array.from(fs.readFileSync("example.gz"))).toJSTemplateLiterals()

const decoded = base128.decode(eval(encodedTemplate))

Char Code (ASCII) :

'\0\1\2\3\4\5\6\7\b\t\n\v\f\r\x0E\x0F\x10\x11\x12\x13\x14\x15\x16\x17\x18\x19\x1A\x1B\x1C\x1D\x1E\x1F !"#$%&\'()*+,-./0123456789:;<=>?@ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\]^_`abcdefghijklmnopqrstuvwxyz{|}~\x7F'

Encode this jpg file, use base128 is 102KiB smaller than base64:
