How it Works

Five steps. Almost no learning curve. Built so a first-time visitor can finish without a tutorial.

1. 1

   Upload your image

   Drag and drop a PNG, JPG, or JPEG. Preview appears immediately.

2. 2

   Crop the plot region

   Keep only the plotting area. Ignore titles, legends, captions, and margins. You can adjust later.

3. 3

   Calibrate the axes

   Click Origin, Maximum X, and Maximum Y. Enter min/max values. Choose linear or log scale for each axis.

4. 4

   Extract automatically

   Plot2CSV finds the number of visible line or scatter series and labels them Y1, Y2, and more. Review each overlay before export.

5. 5

   Edit and download

   Select any series, drag/add/delete points, then download aligned X, Y1, Y2 columns as CSV or Excel — edits included.
