Build a pie chart from labels and values with percentage labels, a legend and six colour themes — download as SVG or PNG.. Pie Chart Maker is a free online tool from the ToolsRift Charts & Data Tools collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Enter one label and one number per line as CSV, choose a colour theme and decide whether to show values or percentages, then download the finished pie chart as SVG or PNG.
Each slice angle is its value divided by the total of all values, so the percentages always add up to 100%. The tool ignores blank cells and skips zero or negative values, since a pie chart cannot represent a negative share.
Between two and about eight slices is readable. Beyond that the labels start to collide, so the tool automatically hides the inline label on any slice smaller than a few percent and relies on the legend instead, keeping the chart clean.
Yes. The SVG export is pure vector geometry with real text, so it prints at whatever resolution your printer or press supports. The PNG is rasterised at 2x for crisp on-screen use, and you can switch the export background to white so it drops straight into a document.
