JavaScript Compress Base64 Image
/*
Maybe string compression is the solution for you.
This converts the data to byte arrays.
There are multiple implementations and algorithms around, for instance
LZMA-JS A standalone JavaScript implementation of the Lempel-Ziv-Markov chain (LZMA) compression algorithm.
