What OnlineWhiteboard.org is

OnlineWhiteboard.org is a free browser-based whiteboard for drawing, diagrams, notes, image annotation, and visual brainstorming. Its tools include pens, a highlighter, shapes, text, sticky notes, arrows, and connectors, along with presentation mode. Users can create several boards and switch among them during one session. Boards can be exported as PNG or PDF, or saved as editable JSON project files; exports have no watermark. The site describes using the board during Zoom or Google Meet lessons, and says exported files can be shared through email, Google Classroom, Teams, Slack, or other platforms. It lists web, Android, iOS, macOS, and Windows support, plus browsers including Chrome, Firefox, Safari, Edge, Brave, and Opera, as well as Chromebook. Board content is processed in the browser and is not sent to or stored on the service's servers during normal use. The privacy policy says hosting infrastructure may collect standard server logs, and makes no claim of compliance with a specific data-protection regulation. Save work before refreshing or closing the tab: session data is cleared when the tab closes. The free plan costs nothing, with no subscription or account required.

Who it suits

The site names teachers, students, remote teams, designers, creators, project managers, and personal users as audiences. It can suit lesson activities, visual planning, or individual brainstorming where saving work before closing the tab is practical.

Limits

The free session clears its data when the browser tab closes, so work must be saved before leaving. Guest collaboration is unavailable.

Getting started

1. Open https://onlinewhiteboard.org/ in a supported browser
2. Create a board and use the drawing, diagram, note, or annotation tools
3. Switch between multiple boards during the session
4. Save work before refreshing or closing the tab
5. Export the board as PNG, PDF, or editable JSON

Verdict

OnlineWhiteboard.org offers a broad set of whiteboard tools and several export options at no charge. Its key limitation is session persistence: save your work before closing or refreshing the tab.
