Features

Capture modes

  • Full page — stitches the entire scrollable page, including content below the fold (Alt+Shift+F)
  • Select area — drag to pick any region of the visible viewport (Alt+Shift+R)
  • Capture element — hover-pick any scrollable element (sidebar, chat pane, modal) and capture its full content
  • Capture delay — 3s or 5s delay to catch menus, dropdowns, and hover states

Shortcuts can be rebound at chrome://extensions/shortcuts.

Editor

Every region capture opens in a dedicated annotation editor:

  • Rectangle, ellipse, line, arrow — customizable stroke color, width, and fill
  • Text labels with Small / Medium / Large sizing
  • Auto-numbered badges for step-by-step tutorials
  • Highlight — translucent marker overlay that keeps text legible
  • Marker — freehand drawing
  • Blur — real pixel blur at Light / Medium / Strong intensity
  • Redact — one-click solid black bar
  • Eyedropper — pick any color directly from the screenshot
  • Frame — wrap the screenshot with padding, gradient or solid background, rounded corners, and drop shadow for share-ready visuals

All annotations remain editable: select, move, delete, unlimited undo/redo.

Save your way

  • Download as PNG (region) or JPG (full page) to your Downloads folder
  • Copy to clipboard — paste straight into Slack, email, Figma, Google Docs
  • Or both at once
