Check the image properties that affect the next upload
An image inspector answers a practical question: what exactly is this file before I send it to another system?
Check dimensions and file size together
Pixel dimensions tell you the canvas size. File size tells you how many bytes you are asking the destination to accept. Neither one alone describes the whole quality picture.
Aspect ratio and megapixels are useful context when a form, website or print workflow gives you a specific requirement.
Treat destination rules as the final authority
Upload requirements differ between services. Use the inspector to understand your file, then compare those properties with the destination instructions before editing.
Frequently asked questions
How can I check image dimensions?
Load the image and inspect its width and height in pixels. The tool also reports aspect ratio and megapixels.
What is the difference between image size and dimensions?
File size is the amount of data in bytes. Dimensions are width and height in pixels.
Does a larger image file mean better quality?
Not necessarily. File size depends on format and compression as well as pixel dimensions.
What is a megapixel?
One megapixel is one million pixels. It is the product of the image width and height divided by one million.
