Draw on any webpage. A movable toolbar, screenshots, and a 15-colour palette with Premium. WebPen is a light, fast productivity extension that lets you draw freehand, add annotations, highlight text, and take notes directly onto any webpage using a transparent canvas — no downloads, no sign-up required. It comes packed with a freehand ink pen supporting multiple brush sizes, a quick color palette to toggle between classic drawing colors, an instant eraser, and a "Clear All" command to reset your canvas in one click. You can also capture a screenshot of your annotated page and download it locally with a single click. WebPen is perfect for students annotating research and articles, professionals marking up web content during meetings, or anyone who simply wants to highlight, sketch, or leave notes on any webpage they visit. Your drawings stay completely private — WebPen collects no personal data and works entirely within your browser.
