Engauge Digitizer vs GetData Graph Digitizer: Free vs Paid
⚡ Quick Answer
GetData Graph Digitizer (~$30, Windows only, shareware) and Engauge Digitizer (free, Windows/Mac/Linux) do the same core job: trace curves in graph images and export the numbers. Pay the $30 only if you prefer GetData’s specific workflow — for features alone, the free tool matches or exceeds it.

Frequently Asked Questions
Is GetData Graph Digitizer worth the $30?
It depends. GetData is a polished, simple Windows tool with a long track record — worth $30 if you specifically like its workflow. But Engauge Digitizer performs the same core task (XY curve tracing with CSV export) for free, on Windows, Mac, and Linux.
What are the limitations of GetData Graph Digitizer?
The main ones: it is Windows-only (no Mac or Linux version), it handles XY graphs but not specialized plot types, and there is no online version. Check the official site for the current version’s exact limits.
Can Engauge Digitizer fully replace GetData?
For the core job — extracting (x,y) data from graph images and exporting CSV — yes. Engauge additionally offers logarithmic/polar axes, cross-platform support, and offline privacy, all free.
Is there a free trial of GetData Graph Digitizer?
Yes, GetData is sold as try-before-you-buy shareware, so you can evaluate it before paying the ~$30 license fee.
