Mesuro

Measure distances, angles, areas, diameters and perimeters directly in any image or PDF file. Set a real-world scale once, get precise measurements in mm, cm, inches or any unit. Load PDF technical drawings with automatic page selection. Edge snap technology locks onto detected contours for sub-pixel precision. Add text annotations, export annotated images or PDF reports. Works entirely in your browser — no upload, no account, no install required.
