What does the Image Dimensions Checker do?
Choose or drop several images at once to see a table with each file’s width, height, simplified aspect ratio (such as 16:9 or 4:3, with orientation), megapixels, file size and format. Download the table as CSV to keep a record.
This is useful before uploading to platforms with strict requirements, and for auditing image sizes on a website project.
How to use the Image Dimensions Checker
- Choose or drag one or more images into the box.
- Read the dimensions table.
- Add more images if needed, or clear the list.
- Download the CSV if you want a record.
Examples
