PDF measure

Measure lengths, areas, angles and radii on a PDF drawing.

Open a PDF, JPG or PNG drawing, set the scale from one known dimension and measure directly on the sheet: lines and polylines, spline lengths, areas, circles with radius, diameter and circumference, a radius through three points and angles. Totals appear in a legend and export to CSV, PNG or an annotated PDF. The drawing stays on your own computer, and you can save your work as a project file or install the tool as an app to use it offline.
