Free Online Image Size Checker
Before uploading a photo to a website, attaching it to an email, or submitting it to a print service, it helps to know exactly how big it is — both in file size and in pixel dimensions. LovePDFImg's Image Size Checker reads this information directly from your image and displays its width and height in pixels, file size, aspect ratio, and megapixel count, all at a glance.
You can check a single image or drop in a whole batch to compare several files side by side. The tool reads the image dimensions by loading the file into the browser and inspecting its natural size, and reads the file size directly from the file object — no server upload required.
