Description
PixelZoomer captures a screenshot of the current webpage and equips you with a suite of pixel-level analysis tools. It is designed for designers, developers, and quality assurance professionals who need to inspect fine details, measure elements, or extract colors from any website. The extension works on any open page, providing an overlay that lets you interact with the captured image without altering the original site.
Features
- Pixel-perfect ruler: Measure distances between any two points on the screenshot with precision down to single pixels. Useful for verifying layout alignment, element spacing, or image dimensions during front-end development or design review.
- Zoom and pan tool: Magnify the screenshot from 100% up to 3200% to examine tiny details, such as anti-aliasing effects, icon edges, or pixel art. Pan across the enlarged image to navigate to different areas without losing context.
- Eye dropper: Click on any pixel to instantly get its color in both HEX and RGB formats. Ideal for matching brand colors, extracting palette references, or checking color consistency across a design.
- Undo and redo: Revert or reapply your last action when using the ruler or other tools, providing flexibility during measurement or color picking without restarting.
- Open screenshot in a new tab: Export the captured screenshot as an image file that opens in a separate browser tab, allowing you to save, edit, or share it with other applications.
Whether you are debugging CSS pixel discrepancies, verifying responsive design, or collecting color samples for a project, PixelZoomer streamlines these tasks directly within your browser without needing external software.
