How do I check image dimensions and aspect ratios?
Upload any image to instantly see its exact width and height in pixels, centimeters, inches, and standard aspect ratio (e.g. 16:9, 4:3, 1:1).
Can I inspect megapixel count and file size?
Yes. The inspector reports exact width and height in pixels, total megapixel count, and the file size in bytes and kilobytes for every loaded image. These numbers update per file, which is useful for checking marketplace upload limits before submitting.
Which image formats can be inspected?
JPEG, PNG, WebP, GIF, BMP, ICO, and AVIF files all open correctly. The tool reads the decoded bitmap dimensions straight from the browser image parser, so even files with wrong extensions or missing headers report their true pixel geometry.
