Free chart maker

Paste or type your numbers, pick a chart type, and download a clean PNG or SVG. It's free, there's no sign-up and no watermark.

The preview is drawn in your browser. PNG is rendered by the Render API from the same data, which isn't stored. Image URLs contain the data, so anyone with the link can read it.

How to use it

  1. Type or paste your data: the first row holds the series names, the first column the labels.
  2. Choose a chart type, title and theme.
  3. Download PNG or SVG, or copy the image URL to embed it anywhere.

What you can make

  • Grouped or stacked bar charts, vertical or horizontal
  • Line and area charts with up to 12 series
  • Pie and doughnut charts with automatic percentages
  • Value labels, $ or % prefixes and suffixes, axis titles

Your chart as a link

Every chart you make here has a permanent image URL on render.cuelark.com. Paste it into a README, a Notion page, an email or a Markdown doc and the image renders there, so you don't upload anything. The URL holds the chart data itself, so anyone with the link can see the numbers. Don't put private data in a shared chart link.

Charts from code or an AI assistant

The same renderer runs behind the Chart image API and the MCP server. Your scripts, spreadsheets, n8n flows or Claude and ChatGPT can make the identical chart from JSON.

Frequently asked questions

Is this chart maker really free?

Yes. Making charts and downloading PNG or SVG is free with no account. There's only a per-minute rate limit to stop abuse.

Do you keep my data?

No. The preview is drawn in your browser. When you download a PNG, the data is sent once to our renderer and isn't stored or logged. A chart image URL holds the data in the link itself.

Can I use the charts commercially?

Yes. Charts you make are yours to use anywhere, with no watermark and no attribution required.

What's the biggest chart I can make?

Up to 2000 × 1500 pixels at 1x, and PNG export goes up to 3x for sharp slides and print. A chart can have up to 500 points per series and 12 series.
