Image Specs – Dimensions, File Size & Page Audit

Description

Inspect image dimensions, file weight, aspect ratio, ALT text and page-wide image issues without opening DevTools. See exactly what an image is doing on a webpage without opening DevTools. Image Specs gives you fast image details on the page you are already viewing, then goes a step further with a one-click page audit that can flag common image problems. INSPECT ANY IMAGE Choose Inspect Images, then hover over an image to see: • Natural image dimensions • Rendered dimensions on the page • Aspect ratio • File type • File weight when Chrome exposes it • Pixel-density / source-to-display ratio • ALT text • Lazy-loading behavior • Responsive source usage • CSS object-fit Click an image to pin the specs card while you work. AUDIT THE WHOLE PAGE Choose Audit This Page to scan visible images and quickly spot things worth checking: • Images being upscaled beyond their natural resolution • Oversized source images displayed much smaller than their original dimensions • Missing ALT attributes • Aspect-ratio mismatches • Heavy images when file-weight data is available Image Specs adds compact dimension badges directly over images and shows a summary panel so you can review the page without hovering every image individually. COPY WHAT YOU NEED Copy a clean specs summary for an image or copy ready-to-use Markdown image syntax directly from the pinned inspector. NO EXTRA IMAGE REQUESTS FOR FILE SIZE Image Specs uses resource timing information already exposed by the browser when it is available. It does not download image files again just to calculate their size. If Chrome does not expose the file weight for an image, Image Specs simply says that the value is unavailable. BUILT FOR DESIGNERS, DEVELOPERS, SEO AND CONTENT WORK Use Image Specs when checking responsive images, debugging blurry assets, reviewing image optimization, checking ALT coverage, validating source dimensions, or just figuring out how large an image actually is. PRIVATE BY DESIGN Image Specs runs only on the webpage where you explicitly invoke it. The extension uses temporary activeTab access and does not request permanent access to every website. Inspected image information stays in your browser and is not stored, transmitted, or used for analytics. No account. No advertising. No backend. No remote code.
