Screenshot Export

Export the current viewport as a PNG with all Calipers measurements, guides, and overlays baked in.

How to export

Press S while Calipers is active. The extension captures the visible tab via chrome.tabs.captureVisibleTab() and triggers a download.

The file is saved as calipers-{timestamp}.png.

What is included

The screenshot captures exactly what you see — dimension labels, measurement lines, alignment guides, box model rings, and ruler overlays are all included in the export.

Tips

• Position your measurements before exporting — the capture is instant.
• Use screenshot exports to attach spacing checks to PRs, design reviews, or bug reports.
