exiftool (OSINT image metadata utility) in the browser (via WebAssembly!)

Overview

The exiftool-webDemo is a groundbreaking web application that simplifies metadata extraction from images, making it accessible for non-programmers. Built with frontend technologies, specifically Svelte, this tool runs entirely client-side and requires no installation, thereby lowering the barrier to entry for users engaged in open source intelligence (OSINT) research. By utilizing advanced technologies like WASI and OPFS, it serves as a modern substitute for traditional command-line tools and outdated GUIs.

This project is noteworthy not only for its functionality but also for its innovative use of existing packages. It leverages zeroperl for Perl emulation and browser_wasi_shim to ensure smooth operation within web browsers. As OSINT researchers increasingly look for reliable tools to analyze publicly available data, this application meets that demand with a user-friendly approach.

Features
