Image Info Viewer
Quick Answer
It reads the image header and shows dimensions, file size, format, aspect ratio, colour depth, and resolution in megapixels.
What Is Image Info Viewer?
Image Info Viewer is a free online image & media tool that view image dimensions, file size, type and basic metadata. An image info tool extracts basic metadata from an image file: dimensions (width and height in pixels), file size, MIME type, and colour depth. Unlike an EXIF viewer, it does not need camera-specific metadata — it reads the image header that every bitmap format includes. The tool supports JPEG, PNG, GIF, WebP, BMP, and TIFF formats. You upload an image or paste an image URL, and the information is displayed instantly. The tool also shows the aspect ratio and the resolution in megapixels. All data is read client-side; the image is never uploaded to a server. Unlike many similar tools, it runs entirely in your browser — no data is sent to any server, no account is required, and there are no usage limits. Whether you are a developer, writer, SEO professional, or casual user, this tool provides instant, accurate results without friction.
