Create custom pie charts online for free. Input your data, adjust styles, and instantly generate and download your pie graph in PNG or SVG format.
Separate values with commas, semicolons, or tabs. The first row can be a header. Enter one category per row with a nonnegative value. Percentages are calculated automatically.
Overview
Understand what the tool solves, how it works, and the boundaries of its data.
Enter category names and nonnegative numbers as rows. For each valid row, the chart calculates its share of the valid-value total:
Share = category value ÷ sum of valid values × 100%
Slice angle = category value ÷ sum of valid values × 360°
For example, values of 40, 35, and 25 total 100, producing shares of 40%, 35%, and 25%. If all entries are multiplied by the same positive factor, their shares stay the same. The result includes a pie or doughnut chart, a category/value/percentage table, and the total. Percentage labels are rounded to one decimal place.
A pie chart communicates how categories contribute to one total. It is easiest to compare when there are only a few categories and the shares differ enough to see clearly. The Office for National Statistics recommends three or four categories ideally and advises against more than six; close-sized slices are often easier to compare in a bar chart. A doughnut chart uses a hollow center but still represents the same whole.
Guide
Follow the workflow and verify inputs and outputs with practical examples.
Enter one category and one number per row. Commas, semicolons, or tabs can separate the two columns. A first row whose second cell is text is treated as a header; otherwise the first row is data.
Check the category names, values, percentage table, and total. The chart updates as the input changes. Invalid rows and negative values are skipped.
Add a title, select pie or doughnut, choose a label style, and turn the legend or hover tooltip on or off. Individual slices can be assigned colors.
Download PNG for a raster image or SVG for a vector image. Before exporting, check that labels remain legible and do not collide.
Use cases
See how the tool fits into real work and everyday tasks.
Enter amounts for non-overlapping departments within the same budget period to show how the entered budget is divided.
Use response counts for the options in one single-choice question. Multi-select counts may exceed the number of respondents and do not describe parts of one whole.
Group costs for one project or month into complete, non-overlapping categories. If categories are missing, the visible shares still normalize the values that were entered.
Q&A
Find concise answers to common questions and confusing cases.
No. A first row with a nonnumeric second cell is treated as a header. If its second cell is numeric, that row is included as data.
Each percentage is displayed to one decimal place, so rounding several slices can produce a displayed sum slightly above or below 100%. The shares are calculated from the unrounded values.
The input is pasted or typed as delimited text; the page does not provide spreadsheet-file upload. Copy the relevant two columns as tab-separated rows before pasting.
Notes
Review scope, result limitations, and important precautions before use.
The parser uses the first two columns of each row. Keep category names free of commas, semicolons, and tabs so the name and number stay in the expected columns. At least one valid named row and a positive total are required. If the total is zero, no meaningful shares can be drawn.
A pie chart always redistributes valid entered values across the chart. It cannot reveal categories omitted from the input, represent independent rates, or make multi-select responses into a true part-to-whole distribution. With many slices or similar-sized values, use a chart that supports easier comparisons.
