From capture to handoff

Capture the part you need

Grab a region for a bug report, a window for context, or an entire display.

  • Stitch a long page into one image so the steps stay in order.
  • Switch to manual scrolling for an app that ignores automatic scrolling.

Point out the details

Add an arrow, a label, or numbered steps so someone reading your report can find the exact spot.

  • Blur details before you share the image.
  • Copy an error message without retyping it, or read a QR code. Recognition runs on your computer.
  • Measure a gap between edges or copy a colour from the image.

Share the capture or keep it in view

Edit, copy, save, or pin from the floating thumbnail. Use its top grip to move the thumbnail.

  • On macOS, drag the image itself to send a PNG file to another app. Copy and save are available on macOS and Windows.
  • Pin an image above other windows to compare layouts or follow instructions. Zoom in to read it, or turn on click-through to use the app underneath.
