Venn Diagram Maker

Make a 2- or 3-circle Venn diagram in your browser — name each set, label every overlap, then download a PNG, SVG, PDF or JSON. Free and private.

Import a Venn (.json)

Load a Venn you saved earlier with the Download → JSON option. Importing replaces what's on the canvas.

Name each circle and label every region — the diagram updates as you type.

How to use

  1. Choose 2 or 3 circles, then give each circle a name — for example "Cats" and "Dogs". The diagram updates the moment you type.
  2. Fill in a caption for each region: what belongs only to one circle, and what belongs to the overlaps where the circles cross.
  3. Pick a format — PNG to share a picture, SVG for a sharp file you can scale, PDF to print or attach, or JSON to save and re-open later — then press Download. Everything is drawn in your browser, so nothing is ever uploaded.

FAQ

Is my Venn diagram sent to a server?

No. The whole diagram is built and exported in your browser, so nothing you type is uploaded. The tool works offline and keeps your work private.

Can I make a Venn diagram with more than three circles?

This maker supports the two most useful and readable cases — two and three circles. Four or more overlapping circles can't show every region with plain circles (they need stretched ellipses and a geometry solver), so they tend to be confusing; three circles cover almost every classroom and planning need.

How do I label the overlapping middle part?

Each region has its own caption box in the panel above the diagram. The "A ∩ B" box is the slice where two circles cross, and "A ∩ B ∩ C" (with three circles) is the very middle where all three meet. Leave a box empty to hide that caption.
