Screenshot Markup Tool: Draw and Annotate in Chrome

A screenshot markup tool focuses specifically on drawing and visual markup — including freehand pencil, lines, arrows, shapes, and highlighting — directly on a captured image. Capture Full Page includes a full drawing panel with adjustable line thickness, Undo/Redo, Zoom, and a professional color picker with RGB/HSL/HEX and eyedropper. All markup happens locally — your images are never uploaded. For the complete editing workflow including cropping and export options, see the screenshot editing workflow. To add structured elements like step numbers and text labels, see how to add annotations to screenshots.

3 Ways to Get It Done

1

  1. 1Capture any screenshot — the image opens in the editor automatically.
  2. 2Click Edit to open the drawing panel with all markup tools.
  3. 3Pencil: draw freehand lines and sketches with adjustable thickness.
  4. 4Line & Arrow: draw straight lines and directional arrows to point out elements.
  5. 5Rectangle: frame areas of interest with outlined or filled rectangles.
  6. 6Highlighter: apply semi-transparent color overlays to emphasize content without obscuring it.

Method 2: OS Markup Tools

Windows Snip & Sketch and macOS Markup offer basic drawing tools but lack the depth needed for professional annotation.

  1. 1Capture a screenshot with OS tools and open it in the built-in editor.
  2. 2Use basic pen, highlighter, and ruler tools.
  3. 3Limited shapes — no arrows, no step numbering, no advanced color controls.
  4. 4Save the file — only PNG output, no PDF export.

Method 3: Dedicated Markup Apps (Skitch, Monosnap)

Standalone markup apps offer dedicated annotation features but require installation, often need an account, and some have premium paywalls.

  1. 1Install a dedicated markup application.
  2. 2Capture or import a screenshot into the app.
  3. 3Use annotation tools — typically arrows, text, shapes, blur.
  4. 4Export — some features require paid subscriptions.

Frequently Asked Questions

What drawing tools does the markup panel include?
The drawing panel includes: pencil (freehand), straight line, arrow, rectangle, highlighter (semi-transparent), text tool, and step numbering (auto-incrementing). You also get a full color picker (RGB/HSL/HEX + eyedropper), line thickness slider, Undo/Redo, and Zoom controls.
Can I adjust the line thickness?
Yes. A thickness slider in the drawing panel lets you control the stroke width for all drawing tools — from thin precise lines to thick bold strokes. The setting applies to pencil, line, arrow, rectangle, and highlighter.
Is there an eyedropper / color picker?
Yes. The color picker supports three input modes — RGB sliders, HSL sliders, and HEX code input. Additionally, the eyedropper tool lets you click on any pixel in your screenshot to pick that exact color, making it easy to match brand colors or existing elements.
Can I export marked-up screenshots as PDF?
Yes. After marking up your screenshot with arrows, text, highlights, step numbers, or any other tool, click the PDF button in the toolbar. The exported PDF includes all your markup exactly as it appears in the editor. You can also save as PNG or copy to clipboard.
Does the screenshot markup tool work offline?
Yes. Capture Full Page works entirely offline — no internet connection required. All markup, editing, and export happens locally in your browser. Your screenshots are never uploaded to any server, making it safe for confidential or sensitive content.
