Make a pie chart online, free
A pie chart answers one question: how is this whole divided? A budget, survey answers, traffic sources, or a vote. Paste the categories and the numbers, and Chartsuno draws the chart in the browser.
How it works
- Paste the categories and the numbers. Two columns are enough: a label and a value. Copy them from a note, a doc, or a spreadsheet.
- Fix any cell in the data editor. Change a value, rename a slice, or group a small category into Other. The chart updates as you edit.
- Choose pie in the chart editor. Set the title and keep the number of slices small enough to read on a slide or a phone.
- Save, export, or share. Previewing does not require an account. Sign in free to keep the chart in My Charts, download a PNG, or copy a share link. A free account includes 10 saved charts a month.
When a pie chart is the right chart
Use a pie when every value is a part of one total and you only have a few categories. If people need to compare numbers that are close together, a bar chart is easier to read. If the story is change over time, use a line graph instead.
Tips for a pie people can read
- Aim for six slices or fewer. Roll the long tail into one Other slice.
- Put the largest slice first so the eye lands on the main share.
- Write the takeaway in the title, for example “Most traffic is direct”, not only “Traffic”.
- Skip the pie when the values are not parts of one whole.
- Is it free?
- You can paste data and preview a chart without an account and without paying. A free account saves up to 10 charts a month, and those saved charts can be exported as a PNG or CSV and shared with a link. Paid plans remove that monthly cap. There is no credit card for the free plan.
- Do I need to sign up?
- Not to paste data and see the chart. Saving to My Charts, downloading a PNG or CSV, and copying a share link need a free account. On the web, Continue with Google creates the account. The iOS app also offers Sign in with Apple.
- Can I change the numbers after the pie is drawn?
- Yes. Edit any label or value in the data editor and the slices update. Save the chart if you want My Charts and the share link to show the new numbers.
- How do I put the pie in my slides?
- Sign in, export a PNG, and drop it into PowerPoint, Keynote, Google Slides, or a doc. You can also copy a share link to the saved chart.
- What if I have too many categories?
- A pie with a dozen slices is hard to read. Keep the largest categories and combine the rest as Other, or switch the chart to bars.
