Method 1: Chrome DevTools
Chrome officially supports capturing an individual node from the DOM Tree.
- Right-click the element and choose Inspect.
- In the Elements panel, make sure the correct node is selected.
- Right-click the selected node.
- Choose Capture node screenshot.
- Chrome saves the image to your downloads.
This is precise and requires no extension, but it is a developer-oriented workflow and does not include Capture's annotation, privacy and reporting tools.
