No more switching between tabs or squinting at two screens side by side. How it works: install the extension, open any page, and drop in an image — drag and drop, paste a URL, paste from clipboard, or use the file picker. Position and scale the overlay, then adjust opacity to compare. - Overlay any PNG, JPG, or SVG on any web page - Adjustable opacity for real-time visual comparison - 4 blend modes (Difference, Invert, Multiply, Overlay) plus Normal — each useful for catching different types of mismatches - Lock the overlay to click through it and interact with page elements underneath - Per-domain persistence: your layers stay saved per site and restore automatically across browser sessions - Multiple layers per domain - Scaling, repositioning, and centering controls - Keyboard shortcuts for common actions - Unlimited simultaneous layers (free tier supports 2) - Folders to group layers - Layer rotation - Dark theme - Custom icon, accent color, and custom CSS Built for frontend developers, QA engineers, agencies, and development teams who need to verify that what they shipped matches what was designed. 350,000+ developers. 10+ years on the Chrome Web Store.

PixelSharp

Sets the image scaling of the page to Nearest Neighbor for sharp pixels PixelSharp changes the scaling of images on the current page to be pixel-perfect when activated. Scaled up pixel art in the browser often ends up very blurry due to the default "linear" scaling method. This scaling works well for general browsing, as most images on the web are high resolution, but is detrimental to pixel art and low resolution images. Activating PixelSharp changes the page scaling to "nearest neighbour", the intended scaling method for pixel art. How to use: The extension was designed to be pinned so that you can simply click the icon to activate it. You can also activate PixelSharp by first pressing the "Extensions" button next to the URL bar and then clicking on PixelSharp in the list of installed extensions. You will need to enable "Allow access to file URLs" for the extension to work on images loaded from your computer. Technical details: The extension only activates when clicked. Clicking the extension icon will trigger a single update to the current page which modifies the display styles to use nearest neighbour scaling. After the page has been updated the extension stops. Reloading the page will clear the page modification, essentially reverting the images on the page back to the original browser scaling behaviour. Image attribution: The "before and after" image was created from real screen captures of the same image at 500% browser zoom scale, before and after using the PixelSharp extension.
