Zpng: a pure JavaScirpt JsExe
Developed with Subzey and Anders Kaare.
JsExe is a Windows program that allows to encode JS code inside a PNG's pixels, and append some HTML code at the end to extract and execute it. This technique is called "PNG bootstrapping", and it's often used in ~1kb JS demos because of the nice gzip compression allowed by the PNG format.
Zpng is a pure JS app performing the same job, with a stronger compression (zopfli) and more simplicity for the user because everything is done in the browser.
