Dimensions, ratio and file size
Three different numbers get called an image's 'size'. Dimensions are the width and height in pixels — what matters for uploads and printing. Aspect ratio is the shape those dimensions form, like 16:9. File size is how many kilobytes the file occupies on disk, which is what upload limits measure.
This checker reports all of them at once, plus megapixels, for as many files as you drop in. If you need the camera and exposure details instead, the EXIF viewer decodes the photo's full metadata.

Frequently asked questions
How do I find the dimensions of an image?
Drop the file above and the width and height in pixels appear instantly, along with the aspect ratio and megapixels. Nothing is uploaded.
What is the difference between image size and file size?
Image size usually means the pixel dimensions (for example 1920 × 1080), while file size is how much storage the file uses (for example 850 KB). This tool shows both.
Can I check several images at once?
Yes. Drop a whole batch and each image gets its own row with full details.
