An online plot digitizer with nothing to install
No download, no Java, no account. Drop the graph on the page and the data comes back in the same tab.
What you can drop in
- A PDF: a paper, a report, or a single figure. Up to 20 MB.
- A picture: PNG, JPEG, a screenshot pasted from the clipboard, a scan.
- Bar charts, line charts, scatter plots, pie charts and survival curves.
What comes back
- The data as a table you can edit, with each value drawn back on the chart.
- Excel, CSV, or a copy for pasting into a spreadsheet.
- If something was missed, you add it by clicking on the chart.
What it costs
Charts drawn inside PDFs are free, without limit: reading them takes no AI model.
A picture takes a model call, so one a day is free and more are sold in packs, paid once, with no subscription.
Good to know
When a PDF holds the chart as a drawing (most figures in papers do), the values are read from the drawing itself. Nothing is estimated from pixels, so a point is as precise as the file is.
A picture (a screenshot, a scan, a PNG or JPEG) is read by an AI model. Every value is then drawn back on the picture as a ring, so a wrong one is easy to see and to correct in the table.
Questions
What happens to my file?
It is read and then discarded. The result stays in your browser.
