I built a browser-based image comparison tool for subtle differences

Hi HN, I built this after getting frustrated trying to compare small differences in AI-generated images and game graphics settings. A lot of tools I tried either felt bloated or required uploading files somewhere. So I made a simple image comparison tool that runs entirely in the browser. Everything stays local — no uploads. It supports slider, split view, fade mode, pan & zoom, and a few other viewing options like grayscale and basic color frequency info to help spot subtle changes. The goal was to keep it lightweight, precise, and easy to use. Curious what you think. https://picdiff.dev/
