A free Venn diagram maker where the overlap is the point
- Free
- No sign-up
- Works offline
Name the sets, fill the regions, and press Present — each overlap is revealed and explained in turn, which is the part an audience actually came for.
Present reveals your Venn diagram one step at a time, on its own.
A Venn diagram is the fastest way to settle an argument about what two things share and where they differ. It is free to make here, needs no account, and works offline.
Most Venn diagrams fail the same way: the circles are drawn, the overlap is left empty, and the reader is left to guess what belongs there. The overlap is the diagram — everything else is context.
Two circles, three circles, and knowing when to stop
Two circles give three regions: left only, right only, and both. Three circles give seven, and seven is where most Venn diagrams stop being readable — a reader has to hold three memberships in mind at once to place an item.
If you need four sets, you almost always want a different diagram. A comparison table handles many attributes across many options far better, and a concept map handles relationships that are not simply membership.
The discipline that makes a Venn diagram good: write something in every region, including the ones you expected to be empty. An empty region is a claim — it says nothing has both properties — and it is worth making that claim deliberately rather than by omission.
Colour is identity here, not decoration
In most diagrams a colour is styling. In a Venn diagram each set's colour is how a reader tracks which region belongs to which set, so Diagramium treats a set's colour as part of its identity: the bulk-styling tools deliberately do not overwrite it.
Overlaps blend the colours of the sets that meet there, so the visual reinforces what the geometry already says.
Present one region at a time
Press Present and the sets appear first, then each overlap in turn, with narration on whichever region carries the argument. It turns a static picture into a short explanation — useful in a lesson, and useful in a meeting where the shared region is the decision.
How to make a Venn diagram, start to export
Open the editor, add two or three sets, name each one, then type the items into each region — including the overlaps. Adjust the colours if the defaults do not match your deck, then export a PNG or SVG, or present it.
Free, private, and offline
Diagramium is free and there is no paid tier. Draw, present and export PNG or SVG without an account; a free account unlocks the animated export formats — GIF, video and animated SVG.
Your diagram is stored in your own browser, not on a server. It keeps working with the network off, and nothing is uploaded unless you choose to publish it.
Frequently asked questions
Is this Venn diagram maker free?
Diagramium is free and there is no paid tier. Draw, present and export PNG or SVG without an account; a free account unlocks the animated export formats — GIF, video and animated SVG.
Can I make a Venn diagram with three circles?
Yes — two or three sets, with all three or seven regions individually labelled. Beyond three sets a Venn diagram becomes harder to read than the table it is replacing.
Can I change the colours of each circle?
Yes, per set. A set's colour is treated as its identity rather than as styling, so applying a look to the whole diagram will not silently repaint one set to match another.
What is the difference between a Venn and an Euler diagram?
A Venn diagram shows every possible overlap even when a region is empty; an Euler diagram draws only the relationships that actually exist. Writing "none" in an empty Venn region gives you the honesty of an Euler diagram while keeping the familiar shape.
How do I export a Venn diagram with a transparent background?
Export as SVG and place it on whatever background you like — an SVG also stays sharp at any size, which a screenshot will not.
