WebPlotDigitizer vs PlotDigitizer: Which Free Tool Wins?
⚡ Quick Answer
WebPlotDigitizer is completely free and open-source in your browser — best for quick, no-install jobs. PlotDigitizer’s free online version is feature-limited (no auto-tracing, no dataset storage); full power needs the $40 Pro desktop app, which adds ternary/pie/map graph types and a modern UI. Rule of thumb: WebPlotDigitizer for free-and-fast, PlotDigitizer Pro if you pay for polish and exotic chart types, Engauge Digitizer if you want a free offline desktop app.
