Many other tools that try to repair corrupted PNG images use only very simple mechanisms to recover the image data, so unfortunately they often fail.
This tool tries to recover a valid image even if only the pure data section (IDAT chunk) of the image is left. The other data needed to display the image (IHDR chunk) is determined via heuristics. Even in the case of an incomplete data section, the data is adjusted in such a way that a valid image can be generated again with a large part of the recovered image data.
In this way, it is often even possible to recover image data that has been intentionally disturbed, e.g. in the context of a CTF photo forensics competition.
There are a lot of articles about online image compression tools in the net, most of them are very superficial. Usually they end with a simple: "It generates smaller pictures, so it's got to be better."
Learn why such statements are most of the time meaningless, understand the technical background, and find out which tool you should use as of today.
