What Diagram Studio does
Sketch flowcharts and mind maps — add boxes, drag them, connect with arrows, and export PNG or SVG. Runs entirely in your browser. The result is a PNG, SVG+XML file you download directly.
How it works
crypto.getRandomValues, qrcode-generator for QR, and color.js for OKLCH-aware color manipulation. The processing code runs inside the page, so your file is not uploaded to a server — you can confirm this in your browser's DevTools → Network tab.
