Free Online Pie Chart Maker
Pie Chart Maker turns your raw numbers into clean, proportional pie charts directly in your browser. Enter labels and values on the left, pick your slice colors, and watch the chart render instantly on the canvas. You can toggle between five distinct chart types within one workspace: standard pie, donut, exploded, semi-circle, and rose (Nightingale). Populate your slices automatically by uploading CSV or JSON files, then fine-tune labels, legends, and rotation to achieve the perfect look. When you are ready, download your chart as a PNG or SVG, or copy it straight to your clipboard. Since all rendering takes place locally on your device, your data stays private and never touches a server.
Pie Chart
Standard circular chart divided into proportional slices with customizable colors, labels, and percentage display.
Donut Chart
Hollow-center pie chart showing the total value in the middle with an adjustable ring width for flexible layouts.
Exploded Pie
Separates every slice from the center for emphasis, making individual segments stand out in presentations.
Semi Circle
Half-pie format ideal for dashboards and gauge-style layouts where vertical space is limited.
Rose Chart
Nightingale-style chart where slice radius varies by value, creating a flower pattern for magnitude comparison.
Online Pie Chart Maker with File Upload and Customization
Building a compelling pie chart starts with getting your data in. Type labels and values directly into the panel, or drag and drop a CSV or JSON file to populate slices in seconds. Each slice gets its own color picker so you can match your brand or presentation theme exactly. The chart title field sits below the data rows, and the live preview updates instantly as you make changes, so there is no guessing about the final result.
Upload CSV or JSON Data Files
Click the Upload button in the toolbar or drop your file into the data panel. This generator supports CSV files with comma, tab, or semicolon separators and JSON arrays using label and value properties. Automatic detection skips header rows so your data imports cleanly without any manual cleanup. Once loaded, tweak individual slice colors or rearrange values to match your preferred order.
Switch Between Five Chart Types Instantly
Switching between Pie, Donut, Semi, Exploded, and Rose modes takes just a single click using the toolbar. Your data stays intact across switches, so you can quickly compare how different chart formats represent the same information. Donut mode adds a center total display and adjustable ring width. Rose mode varies the radius of each slice by its value, creating a Nightingale pattern for magnitude comparison.
Export Pie Charts as PNG, SVG, or Clipboard Image
Once your chart looks right, pick the export format that fits your workflow. High-resolution PNGs are perfect for slides, social media, or reports. SVGs offer perfect scalability for professional print and web projects. If speed matters, the Copy button puts a PNG directly onto your clipboard, ready to paste into Google Docs, Notion, Slack, or any other tool that accepts images. No watermarks, no signup, and no limits on how many charts you create.
High-Resolution Output for Presentations
The canvas automatically matches your device pixel ratio, exporting at 2x or 3x resolution on high-DPI displays. Your pie charts stay crisp and sharp in everything from PDF reports to large-screen presentations without any extra steps.
Customize Labels, Legends, and Rotation
Open Chart Settings to fine-tune every visual detail. Place labels outside the slices, inside them, or turn them off entirely. Position the legend on the right side or at the bottom, or hide it when you prefer a cleaner look. The Start Angle slider rotates the entire chart so you can orient the first slice wherever it looks best. Toggle percentage display, raw values, and sort-by-value to control exactly what information appears on the chart.
Free Pie Chart Maker for Students, Marketers, and Data Analysts
Whether you are a student visualizing survey results for a class project, a marketer breaking down campaign spend, or an analyst presenting quarterly revenue splits, this tool delivers polished visuals in seconds. You gain immediate access to every feature without needing to create an account. Exports come in full resolution and are completely free of branding or watermarks. Because nothing is stored on a server, your data disappears the moment you close the tab, making it a secure choice for sensitive information like company finances or confidential research data.
No Signup, No Watermark, No Limits
You get access to every chart type, customization option, and export format right away. There are no paywalls, no premium tiers, and no restrictions on how many charts you can create. Once you close the browser tab, all session data is permanently removed from memory. Privacy is built into the tool by design.
Client-Side Processing for Data Security
Chart rendering happens entirely within your browser using the HTML Canvas API. No labels, values, or uploaded files ever leave your computer or travel across the network. This client-side approach makes the tool suitable for handling confidential data like internal budgets, academic grades, or proprietary research numbers.
