UniSS by therealmutlusen

Capture, annotate, and save web pages with UniSS.

Take a screenshot of the visible area, a selected region, or a full web page. Use the built-in editor to highlight important details, add notes, and prepare your image without leaving your browser. Useful for bug reports, work notes, tutorials, and visual feedback.

• Visible area: Capture the part of the active tab currently on screen.
• Region or element: Select a page element or drag to define a custom area within the visible viewport.
• Full page: Automatically scroll the page and combine captured sections into a single image.

• Draw freely with the pen tool, or add lines and arrows.
• Highlight important details.
• Create filled or outlined rectangles and ellipses.
• Add text with adjustable colors, fonts, sizes, bold, and italic styles.
• Select, move, resize, or delete your annotations.
• Crop your image and undo the last action.

Save screenshots as PNG, JPEG, or WebP, with adjustable quality for JPEG and WebP. In browsers that support image clipboard writing, copy your screenshot as PNG and paste it into other applications.


Choose your default capture mode, image format, and export quality. Optionally capture immediately when you click the extension icon, or include the page title and URL in your screenshot.

Choose from 71 interface languages, including English. Some languages use English fallback text for untranslated items.


UniSS requires no account. Screenshots and settings are processed locally on your device, and captures are never uploaded to remote servers. UniSS sends no analytics or tracking data.

Clear temporary captures from Settings without changing your preferences or deleting downloaded files.

• Capture works on HTTP and HTTPS web pages. Internal browser pages and extension stores cannot be captured.
• Full-page capture is subject to browser image-size limits on very long pages.
• Copying images to the clipboard depends on browser support.
