Image Forensics

Error Level Analysis (ELA) compares an image to a recompressed version of itself and visualizes the differences. Areas with higher error can sometimes indicate editing, compositing, or different compression histories.

How to use the tool

This tool performs Error Level Analysis (ELA) by comparing an image to a recompressed version of itself and visualizing the differences; areas with higher error levels can sometimes indicate edits, compositing, or differing compression histories in visual content.
It is designed for investigative and OSINT workflows where you want a quick, visual indication of potential manipulation to support deeper analysis, not as definitive proof of tampering for legal conclusions.
