  A similar approach is (over)used for codegolfing, namely the PNG bootstrapping method [1] [2] [3]: your code is compressed into a PNG image and the bootstrap in HTML gets appended to the PNG file to decompress and eval the code. The exact method requires some experiments, as browsers change their rules to determine which is a valid image and which is a valid HTML.

Yes I wrote that part of code and that required way too much algorithm: https://github.com/xem/terser-online/blob/5cc33125/compress.js#L114-L309 https://github.com/xem/terser-online/blob/5cc33125/compress....)
