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

  1. Choose or drag one or more images into the box.
  2. Read the dimensions table.
  3. Add more images if needed, or clear the list.
  4. Download the CSV if you want a record.

Examples

Upload requirement

A marketplace requires 1000 × 1000 minimum: check that all product photos meet it before uploading.

Common use cases

  • Checking upload requirements
  • Auditing website images
  • Sorting photos by orientation

Features and benefits

  • Private by design — your data is processed on your device and never uploaded.
  • Free with no account, no watermark and no usage limits.
  • Works on phones, tablets and desktops in any modern browser.

Limitations to know

  • Dimensions are read from the image as the browser decodes it, which already applies any EXIF rotation.

Width and height are divided by their greatest common divisor, and common ratios are recognised (e.g. ≈16:9).
