Image Size Inspector

Description

Inspect images and pick colors from anywhere on your screen — dimensions, palette, hex codes, all auto-copied. 100% local. Image Size Inspector — inspect any image, pick any color, in one right-click. Right-click any image on any webpage to see its full technical details in a clean inline panel. Click the toolbar icon to sample colors from anywhere on your screen. Built for designers, developers, SEO specialists, and accessibility auditors who need pixel-level facts without opening DevTools or downloading the file. 100% local. Zero data collected. No accounts, no telemetry, no remote servers. WHAT YOU SEE WHEN YOU RIGHT-CLICK AN IMAGE - Original (intrinsic) dimensions and currently-displayed dimensions, shown side by side, so you can spot oversized images at a glance. - File size, computed accurately from the actual image bytes — works on CDN-served and lazy-loaded images. - File format and colour profile (sRGB or embedded ICC), detected from the file's own header. - A five-colour palette extracted from the image, with HEX codes one tap away from your clipboard. - Alt text and ARIA label, surfaced for quick accessibility checks. SCREEN COLOUR PICKER (new in v3.0) Click the toolbar icon and the native eyedropper opens. Sample any pixel visible on your screen — anywhere, not just inside a webpage. The HEX value is auto-copied to your clipboard and saved to a recent-colours list that persists between sessions. Powered by Chrome's built-in EyeDropper API, so the sampling is precise and no screen-recording permissions are needed. BROAD IMAGE FORMAT SUPPORT The inspector handles every common raster and vector format you'll meet on the modern web, including older legacy formats. If your browser can render the image, the inspector can read it. WHO IT'S FOR - Designers — match colours across mockups, screenshots, and live sites without leaving the page. - Developers — sanity-check image dimensions and file sizes during a build review. - SEO specialists — spot oversized hero images and missing alt text in seconds. - Accessibility auditors — verify alt attributes and ARIA labels on any page. - Photographers and editors — sample colours from references and extract palettes from inspiration. PRIVACY The extension makes no network requests of its own. Image bytes are fetched from the same origin your browser already loaded them from. Picked colours are stored locally with chrome.storage.local — never synced to your Google account, never transmitted, automatically deleted when you uninstall. FREQUENTLY ASKED Does it work on lazy-loaded or CDN-hosted images? Yes. The inspector reads the image's actual rendered state on the page. Does it work on single-page apps? Yes. The inspector binds to the live DOM and continues working after client-side navigation. Is the colour picker accurate? It uses Chrome's native EyeDropper API, so it samples real on-screen pixels. Can I clear my recent colours? Yes, anytime via the Clear button in the toolbar popup. Is the extension free? Yes — free forever, no paid tier, no ads inside the extension.
