Measurement Demo

Manual markup only. Upload a photo, add lines and labels, type measurements, then export a PNG. Work is saved locally in your browser.

Tip: drag a line by its body, drag the white dots to adjust endpoints, and drag a point to reposition. Tap a point to edit it. Select a line, set name/measurement, and tap Confirm to show line text. Select an item and press Delete (or use the Delete button) to remove it. Nothing is uploaded to a server.
