Venn Diagram Maker: Type into Every Overlap, Save the Picture
Name your sets, then fill in what belongs to only one, to two, or to all of them. The diagram redraws as you type, and the labels tell you which box fills which part.
The diagram is drawn in your browser and your text is never uploaded. What you type is kept on this computer for next time.
For comparing two or three things on one slide
A Venn diagram earns its place when you want to show what two options share and where they differ. A designer comparing two page builders, a teacher showing two kinds of animals, a team deciding which product ideas overlap with which customers. Three circles is the practical limit, since after that the overlaps stop being readable.
Pick Two or Three under Circles. Give each set a name. The boxes below are named after your sets, so the box for the overlap of A and B reads as the names you typed, followed by the words only or and. Write one item on each line, and the diagram places them in the right part.
Which box fills which part
| Box | It fills |
|---|---|
| Only A, Only B, Only C | The part of a circle that no other circle touches |
| A and B | The overlap of two circles |
| A and C, B and C | The other overlaps, in the three circle version |
| All three | The middle where all circles meet |
In the two circle version the A and B box is the whole overlap. In the three circle version it holds the part that is in A and B but not in C, so the labels say only to keep this clear.
Colour, title and saving
- Title. A short heading above the circles. Leave it empty to give the circles more room.
- Colours. Violet, red and green, Blue, yellow and pink, Soft, or My colours, where you pick one colour for each set.
- Background. White, Dark or See-through.
- Output. Save PNG, SVG or PDF, or Copy picture to paste straight into a document.
The circles are see-through, so the overlaps show a blend of the colours. SVG is the right choice if you plan to restyle the diagram later in a design app, since the circles and text remain separate objects.
A worked example to copy
The form opens with a small sample so you can see the idea at once. Two sets are named Cats and Dogs. Purr and Climb trees sit in the first circle only. Bark and Fetch sit in the second only. The overlap holds Pets and Four legs. Replace each line with your own and the picture follows.
The same method works for business questions. Put the services you offer in one circle and the problems a customer has in another. The overlap shows where you can actually help, and the single-set parts show gaps on either side. Three circles can add a third view, such as what a competitor offers, though the middle part gets crowded quickly.
Print the result on paper before a meeting if you can. Colour overlaps that look clear on a laptop sometimes blur when printed in grey.
Keeping the text readable
Each part of a diagram has a fixed amount of space. If you type more lines than fit, the extra lines are cut off from the picture and a warning names the box that is too full. The fix is to shorten the items, or to use fewer of them.
- Use single words or short phrases, not sentences.
- Count the lines in each box before you save, and keep the busiest box to a handful of items.
- Move detail into the slide text beside the diagram.
- Check dark backgrounds on a projector, where pale colours can wash out.
When a comparison is meant for a sales page, a table is often clearer than circles. Our guide to Webflow versus WordPress for a service business uses that approach.
Frequently asked questions
How many circles can I use?
Two or three. The choice is at the top of the form, and the extra boxes for the third set appear when you pick Three.
How do I add items to the overlap?
Type them in the box for that overlap, one per line. The labels above each box are named after your sets.
Why is some of my text missing in the picture?
A part of the diagram only has room for a limited number of lines. The tool warns you which box is too full, and shortening the items brings the text back.
Can I choose my own colours?
Yes. Pick My colours and set one colour for each set.
Can I put the diagram on a dark slide?
Yes. Choose the Dark background, or See-through to place the diagram on any colour.
Is my text sent anywhere?
No. It is drawn in your browser, and it is kept on this computer only so the form is filled in next time.
