PlainCanvas is a simple browser sketchpad for drawing ideas, diagrams, notes, and transparent PNG graphics without installing software or creating an account.
Use the pen, eraser, line, rectangle, circle, fill, and text tools for fast visual notes. The canvas is designed for quick sketches rather than complex project management.
Switch between pen, eraser, line, rectangle, circle, fill, and text with simple letter shortcuts so quick diagrams take fewer clicks.
Insert a flowchart, meeting-note, or wireframe layout before drawing so common visual notes do not start from an empty canvas.
Save or copy your drawing as a PNG for documents, slides, emails, or simple design mockups. Choose a white, colored, or transparent background before exporting.
Start drawing immediately. PlainCanvas stores the latest work in your browser to reduce accidental loss, but important sketches should still be exported manually.
Use rectangles, straight lines, and short labels to explain a process before moving it into a document or slide deck.
Add text to identify steps, objects, arrows, or rough interface ideas without opening a heavier design app.
Turn decisions, relationships, and next steps into a small PNG that can be saved with the rest of your notes.
Block out a website, app screen, or landing page idea before moving into a heavier design tool.
