Image Resolution Checker
Find out the true resolution of any image — pixel dimensions, megapixels, aspect ratio, orientation, format and file size. Analysis happens locally, so your image is never uploaded to a server.
What the checker reads from your image
Pixel dimensions
The true width and height in pixels, read directly from the file. These are the numbers that determine how large the image can be printed before it looks soft.
Megapixels
Total pixels in millions — width × height ÷ 1,000,000. A 12 MP image from a phone is around 4032 × 3024 pixels, for example.
Aspect ratio & orientation
The shape of your image (such as 4:3, 3:2 or 16:9) and whether it's landscape, portrait or square — useful before ordering prints so you know if cropping will be needed.
Format & file size
The format detected from the file and its size on disk. Where EXIF resolution metadata is safely available it is shown too.
