Capture & edit screenshots with privacy-first design RadKit is a free, open-source screenshot and screen recording extension that runs entirely on your device. No accounts, no servers, no data collection — just fast, private capture tools. SCREENSHOT CAPTURE • Five capture modes: visible viewport, select area, full page, timed delay, and screen/window picker • Built-in annotation editor with arrows, text, shapes, blur, crop, pencil, and lines • Export as PNG, JPEG, or copy straight to your clipboard • All captures saved locally so you can revisit them later SCREEN RECORDING • Record your entire screen, a single window, or a browser tab as WebM video • Choose your frame rate (15/24/30/60 fps) and resolution (up to 4K) • Optional audio: microphone, system audio, or both • Circular webcam overlay you can drag anywhere on screen • Floating control bar with pause, resume, stop, and discard • Preview recordings in the browser before saving PRIVACY FIRST RadKit makes zero network requests. Every capture, edit, and export happens inside your browser. There is no analytics, no telemetry, and no tracking. Your data never leaves your machine. KEYBOARD SHORTCUTS • Alt+S — Capture the visible viewport instantly • Alt+D — Pick a screen or window to capture Free and open source under the MIT License.
