Visual Whiteboard — Free Online Diagram Maker

Draw a flowchart, process diagram or architecture sketch

Choose a template or begin with a blank canvas. Drag rectangles, circles, arrows and connectors; type labels, move or resize shapes, and use freehand drawing. Zoom, pan and undo directly in the editor.

Real editable drawings, stored locally

Download an Excalidraw scene (.excalidraw) and reopen it later with its shapes and text intact. Export PNG or SVG for documents or further image processing. Drawings are autosaved to this device. If browser storage is cleared, only your downloaded backup survives.

Whiteboard or Mermaid diagrams?

This visual whiteboard is for freehand sketching and direct manipulation of shapes. Mermaid Diagram Studio creates diagrams from source text instead. SVG and PNG imports are flattened images, not converted into editable Excalidraw shapes.

Next steps

Download PNG for Image Converter, Compress Image, or Image Difference Checker. Save SVG for a compatible SVG editor. No remote collaboration or third-party storage is enabled.
