CODE IMAGE OBFUSCATOR

This library lets you store any data inside any image and retrieve it later. It can be a text, a script or another image. Please use it responsibly! Do not use it for an illegal purpose.

Motivation

Attempt to hide a javascript file during transmission.

Attention

Support only png without transparency. Because the transparency destroy the data
