Image Error Level Analyser « le: novembre 02, 2012, 23:30:03 pm »

Image error level analysis is a technique that can help to identify manipulations to compressed (JPEG) images by detecting the distribution of error introduced after resaving the image at a specific compression rate. You can find some more information about this tequnique in my blog post about this experiment and in this presentation by Neal Krawetz which served as the inspiration for this project. He also has a nice tutorial on how to interprete the results. Please do not take the results of this tool to seriously. It's more of a toy than anything else.
Drag & Drop an image onto this page to analyze it.

You are identified
You are alone
You forgive
