Make a free pie or doughnut chart in minutes: add labels and values, get automatic percentages, and download a clean PNG or SVG.
A pie chart maker turns a short list of labels and values into a circle divided into slices, where each slice shows one part's share of a whole. CodexFuse's free Pie Chart Maker does exactly that: you add your labels and values, it works out the percentages, and you download the result as a PNG or SVG.
That simplicity only works when the data fits a whole. If your numbers do not add up to a meaningful total, a pie chart will invent a story that is not there.
What is a pie chart maker, and what does it actually do?
A pie chart maker is a free online tool that converts categories and their values into proportional slices of a circle, with each slice labelled by its percentage of the total, so you can see at a glance which parts dominate and which are small. You enter the data, the tool calculates the angles and percentages, and you export a finished chart instead of drawing angles by hand.
The CodexFuse version keeps the workflow short. Add labels and values, switch on doughnut style if you want a centre hole, then download a PNG or SVG. It highlights the biggest slice automatically and includes a shares table, so a reader who wants exact figures does not have to guess from slice sizes alone.
When does a pie chart help, and when does it mislead?
A pie chart helps when your question is about shares of a single whole, such as where a budget went or how a week's orders split across products, because the circle itself represents 100% and every slice is read against that total. It misleads when the question is about change over time, ranking many items, or comparing values that are close together, because slices hide small differences and a circle has no time axis.
Use this quick test before you open the tool:
- One whole, few parts: your categories add up to a total that means something, with five or six parts at most.
- Shares differ enough to see: the largest and smallest parts are not nearly identical, or the chart will look like equal slices.
- No negative values: a negative slice cannot exist in a circle, so debts or losses need a different chart.
- Not a timeline: if the point is what changed month by month, you need a line or bar chart, not a pie.
If you have more than six categories, do not force them into a pie. Group the smallest into "Other", or switch to a bar chart where long lists stay readable. A pie with twelve thin slices tells the reader nothing except that you did not want to choose.
How do you make a pie chart with the CodexFuse tool?
You make a pie chart by entering each category and its value, checking that the percentages look right, choosing pie or doughnut style, and downloading the file you need for print or for the web. Most of the time should be spent checking the data, not styling the chart.
- Add your labels and values: open the Pie Chart Maker and type each category with its number — for example, Bread 420, Cakes 360, Pastries 240, Drinks 180.
- Check the automatic percentages: confirm the shares table matches what you expect before you export anything.
- Pick pie or doughnut: switch on doughnut style only if you want a centre label; the hole adds no data.
- Download PNG or SVG: take a PNG for slides and documents, and an SVG for a website, where it stays sharp at any size.
Read the shares table before publishing. If a slice says 35% but you expected 25%, the error is almost always in the input — a mistyped value or a missing category.
A worked example: one bakery, one week, one clear picture
Fictional scenario: Maria runs a small neighbourhood bakery and wants a simple chart for her staff noticeboard showing where last week's sales came from. She wants her team to see, without a spreadsheet, which lines carry the week.
- Bread: 420 units sold.
- Cakes: 360 units sold.
- Pastries: 240 units sold.
- Drinks: 180 units sold.
The total is 1,200 units. The tool turns those four numbers into 35% bread, 30% cakes, 20% pastries and 15% drinks, with bread highlighted as the biggest slice. Maria downloads a PNG for the noticeboard and keeps an SVG for the bakery's website, beside the weekly menu.
The result changes the conversation in a useful, limited way. Bread and cakes together make 65% of sales, so a stock problem in either line matters far more than one in drinks. What the chart does not do is explain why bread sells well, or whether Maria should change her prices. A chart frames decisions; it does not make them.
Keep labels short and plain. "Bread" and "Cakes" read instantly; "Artisanal sourdough product line (retail channel)" does not. If a label needs explaining, put that explanation in the paragraph beside the chart, not inside the slice.
If your budget, sales split or survey results live in rows of numbers that nobody reads, CodexFuse gives you this free pie chart maker plus fully managed hosting on credits — so the page your chart lives on stays fast, backed up and looked after, with no subscription to babysit.
Get Started with CodexFusePie, doughnut or bar: which one fits your data?
A doughnut chart shows the same shares as a pie chart but with a hole in the middle, which is useful only when you want a centre label or a less heavy layout, while a bar chart is better when you need exact comparisons, many categories, or values that are close together. The data should choose the chart, not the other way round.
| Chart type | Best for | Avoid when |
|---|---|---|
| Pie | Shares of one whole, 2–6 parts | More than six parts, or nearly equal values |
| Doughnut | Same shares, with a centre label | You need precise reading — the hole makes slices harder to judge |
| Bar | Ranking, many categories, close values | The whole-total story matters more than the ranking |
If you are torn, ask one question: does the reader need "what share is this of the total" or "which is bigger, and by how much"? The first points to a pie; the second to a bar chart. A general chart maker lets you test both, and an infographic maker is the next step if you want to combine the chart with a short written story.
What are the honest limits of a pie chart maker?
A pie chart maker cannot show change over time, cannot handle negative values, and cannot make small differences readable — if two slices are 24% and 26%, most readers will see them as the same size, and no colour choice fixes that. It also hides absolute numbers unless you include the shares table, so a 50% slice of 100 sales looks identical to a 50% slice of 100,000 sales.
How to use your pie chart on a website without babysitting a server
Most pie charts die in a downloads folder. The useful version lives where people see it: a report page, a team update, or a small business website. That page still needs hosting, backups and email that work while you run the business, which is where CodexFuse's managed platform fits.
- Make the chart first: build it in the free tool and download the SVG version for the web.
- Put it on a managed site: host the page on CodexFuse, where hosting, updates and security are handled for you.
- Pay with credits, not a subscription: top up credits and use them across hosting, business email and backups as you need them.
- Keep the source numbers backed up: store the original labels and values with your site backups, so you can rebuild the chart next month.
This is not a reason to move your whole business for one chart. But if site updates, email fixes and backups already eat your weekends, one managed platform on credits removes several small chores at once.
If your chart is part of a bigger report, see how a status report turns scattered updates into something people read, and how a flowchart maker explains a process when a share chart is not enough.
Frequently Asked Questions
Is the CodexFuse pie chart maker really free?
Yes. The tool page states it is free and unlimited: add labels and values, choose pie or doughnut style, and download a PNG or SVG. Paid CodexFuse services are separate.
How many slices should a pie chart have?
Two to six slices work well. Beyond six, group the smallest into "Other" and show the full breakdown beside the chart.
Should I choose a pie chart or a doughnut chart?
Choose a pie chart by default, and a doughnut chart only for a centre label such as the total. The shares are identical either way.
Can I use the chart on my website or in a presentation?
Yes. Use PNG for slides and documents, and SVG for a website. Include the shares table nearby so readers can check the figures.
Why do my pie chart percentages look wrong?
Almost always, the inputs are wrong: a mistyped value, a missing category, or a wrong total. Re-check the shares table against your source data.
When should I not use a pie chart at all?
Do not use one for change over time, ranking many items, negative values, or nearly identical values. A bar or line chart is clearer there.
Make the chart, check the shares, then publish it where it will be seen
A good pie chart is a small thing done properly: one whole, a few honest parts, percentages you have checked, and a file format suited to where it will live. Start with the question — "what share is this?" — and only then open the tool.
Try it now: open the free Pie Chart Maker, enter your own labels and values, and download a chart your readers can actually understand. Then, if your website, business email and backups are still eating your weekends, move them to CodexFuse — one fully managed platform on credits, no subscriptions, no server babysitting.
