Most people rely on a built-in snipping tool, only to find it missing on a shared computer, a Chromebook, or a MacBook. This browser-based snipping tool fixes that immediately. Capture any area of your screen, annotate it with a full suite of drawing tools, and export it as a clean PNG file without downloading any software or creating an account.
How It Works
- Capture or Upload: Click "Capture Screen" and drag to select the region you want. The tool uses the browser's native Screen Capture API to pull that area directly onto the canvas. If you already have an image, click "Upload Image" to load a PNG, JPG, or WebP file from your device instead.
- Annotate on Canvas: Select any drawing tool (pen, highlighter, line, rectangle, circle, or arrow), pick a color, adjust brush size, and mark up the image. All rendering happens client-side using the HTML5 Canvas API, so no data is processed on a remote server.
- Save as PNG: Click "Save as PNG" to download the annotated image directly to your device. The export is generated in your browser, meaning your screenshot never leaves your machine.
Compatibility & Support

- Screen Capture: Any browser-visible window, tab, or full screen on Chrome, Edge, Firefox, or Safari

Unsupported Formats

Who Should Use This Tool?
- Students: Capture diagrams, charts, or slides from online courses and annotate them with arrows and highlights before saving as revision notes. No more cropping screenshots manually in Paint.
- Freelancers and Designers: Take precise UI screenshots from a client's live website, draw rectangles around problem areas, and send annotated PNGs as feedback without opening Photoshop or Figma.
- Office Professionals: Document software errors by capturing dialog boxes, circling the exact error text, and attaching the PNG to a helpdesk ticket or internal report.
- Developers: Grab console errors or layout glitches during QA testing, annotate the affected element with an arrow, and drop the PNG directly into a GitHub issue or Slack thread.
Key Features
Here's what separates this tool from generic alternatives:
Browser-Based Screen Capture
Works on Windows, Mac, Linux, and Chromebook with no installation. Any modern browser is all you need.
Full Annotation Suite
Draw with a pen, highlighter, freehand, line, rectangle, circle, or arrow tool. Each is purpose-built for clear visual communication.
Custom Color and Brush Size
Pick any hex color and set stroke size precisely. This level of control is rare in free screen annotation tools.
Multi-Step Undo and Redo
Use Ctrl+Z to undo individual strokes without clearing the whole canvas. Redo restores them just as easily.
Upload and Annotate Existing Images
Load any PNG, JPG, WebP, or BMP from your device directly onto the canvas and annotate it alongside or instead of a screen capture.
Clean PNG Export, No Watermark
One-click download produces a lossless PNG with zero watermarks, branding, or added compression. What you see is exactly what you get.
Why This Tool Beats the Alternatives
- No account creation at any point; many browser-based annotation tools gate export behind a login wall
- No watermark on exported PNGs, which is a common restriction on free tiers of competing tools
- All processing happens client-side, so sensitive screenshots of internal dashboards, financial data, or personal documents never reach a third-party server
- Works across all major operating systems without a browser extension or desktop app install
- All drawing tools including the highlighter, arrow, and smooth anti-aliased pen are available without a paid upgrade
- History panel lets you track and revert changes in a single session, a feature absent from most lightweight screenshot tools
Pro Tips
- Use the Rectangle tool with a bright red color to draw clean bounding boxes around UI elements before sharing screenshots in client feedback documents.
- If you need to annotate a PDF page, convert it to PNG first using the PDF to PNG tool, then load it here for markup.
- After annotating, reduce your PNG file size for email attachments using the Image Compressor tool without losing visible quality.
Select your annotation tool, capture your screen, and download a clean PNG in under 30 seconds. Everything you need to mark up a screenshot and share it is already on this page.
