    Export a clean, high-resolution PNG without an account, paywall, or watermark.

Private by default

Your chart data stays on your device

ChartMaker processes the values you enter directly in your browser. Your datasets are not uploaded to our servers, so you can make a chart without creating an account or storing a project online.

Built for focus

Useful chart tools, without the clutter

This is not a design suite or a dashboard. ChartMaker gives each common chart type a focused workspace with sensible defaults, accessible data, and a quick export path.
