PixelGhost - Pixel Perfect Design Overlay, Screenshots & Visual QA

Compare mockups, capture screenshots, inspect CSS and preview devices. Free visual QA tools for your browser, no account needed.

👻 Small details. Better page reviews. PixelGhost brings visual comparison, screenshots and page inspection into one free browser toolkit. Place your mockup over the live page to spot differences in spacing, color and alignment. ⌨️ Show or hide the widget: Alt+Shift+G. 🖼️ COMPARE WITH PRECISION Add reference images from files, folders, your clipboard or an HTTPS link. Work with multiple layers, adjust position, scale and rotation, then use opacity and blend modes to reveal mismatches. 📸 CAPTURE THE DETAILS Screenshot a full page, visible area or element. Add arrows, notes, highlights and blur, or crop in the editor. Combine captures into a Steps walkthrough and save or copy the finished picture. 🛠️ WORK RIGHT ON THE PAGE 🎨 Color Picker: sample colors, explore page palettes and check contrast. 📏 Page Ruler: measure elements, spacing and alignment. 🔎 Inspector: read computed styles, inspect the box model and try temporary CSS or font changes. 📱 PREVIEW MORE SCREENS Compare up to six device frames side by side. Rotate, sync scrolling and save screenshots or video. Previews run in your desktop browser and do not replace real-device testing. 🧭 LOOK BENEATH THE DESIGN 📦 Assets: find and save images, icons, fonts and media. 👁️ Vision: preview color-vision and sight-loss effects. 🔍 SEO: review metadata, headings, links, structured data and search/share previews. Run the separate AI answers Deep scan for answer-engine readiness. 🧩 Stack: detect frameworks, CMS platforms and libraries from page signals. 🎯 Element Selector: find, highlight and export CSS selector matches. 💾 PICK UP WHERE YOU LEFT OFF Save named projects and restore references and settings for each saved page URL. Keep working from the floating widget with the popup closed. Page tools also work without a reference. 🎁 EVERY FEATURE IS FREE No account, paid tier or trial. Choose light or dark mode, five accent colors and an interface in eight languages. 🔒 LOCAL-FIRST BY DESIGN Workspaces, preferences, captures and score histories stay in your browser profile. No PixelGhost analytics, ads, tracking or uploads to an operator or AI analysis server. Selected images, fonts, previews and site checks still make web requests. Device frames load the site with its usual browser session. Page scripts may inspect references displayed on that page. See the privacy policy for permissions, retention and deletion details. ℹ️ GOOD TO KNOW Protected browser pages are unsupported; framing restrictions can limit device previews. Vision effects are approximations, not medical assessments or accessibility certification. AI answers uses a local, deterministic rubric with same-site probes; scores do not predict rankings or citations. Stack detection can be incomplete and is not a vulnerability scan.
