Description
Compare web pages with reference images using a floating pixel overlay, layers, blend modes, grids, and saved settings. DiffPixel helps you check whether a web page matches a design or screenshot. Click the extension icon, upload a reference image, and compare it directly on the page. You can adjust opacity, position, scale, blend mode, and grid size from a floating panel while the page stays visible. Images and settings stay on your device. DiffPixel does not send your uploaded images to a server. User manual: https://diffpixel.ritastella.com/manual#ja DiffPixel is a simple visual comparison tool for web pages. It is made for the moments when a page looks almost right, but you still want to check spacing, alignment, size, or layout against a design reference. Instead of switching between tabs or image tools, you can place the reference image over the live page and compare them in the browser. After installation, open a page, click the DiffPixel icon, and upload a local PNG or JPG. A floating panel appears on the page, so you can keep the page visible while adjusting the overlay. DiffPixel can help you: - Compare a live page and a reference image in one place. - Spot small visual differences with Difference blend mode. - Adjust position, opacity, and scale with fine control. - Use multiple layers for variants, responsive states, or component checks. - Turn on a grid when you want to inspect spacing and alignment. - Save overlay settings per site, locally in Chrome. - Keep uploaded images private on your own device. DiffPixel does not try to replace design tools or full QA platforms. It focuses on one job: making visual checks easier inside the browser. Highlights: - Floating in-page panel instead of a small browser popup. - Multiple overlay layers with visibility, lock, invert, and delete controls. - Blend modes including Difference, Multiply, Screen, Overlay, Hard Light, and Exclusion. - Fine scale control with decimal input and keyboard arrow adjustment. - Toggleable pixel grid with adjustable size. - Local-only operation. Images and settings stay on the user's device.
