What OnlineWhiteboard.org is

OnlineWhiteboard.org is a free browser-based workspace for drawing, diagrams, notes, image annotation, and visual brainstorming. Its tools include pens, a highlighter, shapes, text, sticky notes, arrows, and connectors, and it also offers presentation mode. Users can create several boards and switch between them in one session, then export a board as PNG or PDF or save it as an editable JSON project file. The site describes classroom use during Zoom or Google Meet lessons, as well as sharing exported files through email, Google Classroom, Teams, Slack, or other platforms. It supports web, Android, iOS, macOS, and Windows, and lists major browsers and Chromebook support. Board content is processed in the browser and is not sent to or stored on the service’s servers during normal use. However, session data is cleared when the browser tab closes, so save work before refreshing or leaving. The free plan requires no subscription or account and adds no export watermark.
