Color Picker, JSON Viewer & QR Tools

Color picker, JSON viewer, QR code generator, and page inspector — 4 offline dev tools, nothing leaves your browser.

Color Picker, JSON Viewer & QR Tools — 4 offline developer utilities in one popup. Pick any color from a webpage, format and validate JSON, inspect page details, and generate a QR code for the current tab — all without leaving the page you're on. Everything runs locally in your browser. Nothing is collected, tracked, or sent anywhere. 🎨 COLOR PICKER Sample any pixel on any webpage using Chrome's native eyedropper tool. Get the color instantly as HEX, RGB, and HSL, copy any format with one click, and keep a running history of your last 12 picked colors for the session. 🔧 JSON VIEWER Paste JSON to format and validate it with syntax highlighting, or click "Format this page" to pretty-print a raw JSON API response you're currently viewing. Catch syntax errors instantly, minify for sharing, copy the formatted result in one click. ℹ️ PAGE INFO See the current page's title, URL, meta description, viewport settings, canonical link, screen resolution, device pixel ratio, and your browser's user agent — all in one glance, no digging through DevTools required. 📱 QR CODE GENERATOR Instantly generates a scannable QR code for the current tab's URL (or any text you type), with adjustable error-correction level and one-click PNG download. Built on a from-scratch QR encoder — no third-party service, no data leaves your device.
