Frequently Asked Questions

How are megapixels (MP) calculated from image dimensions?

Megapixels equal (Width in pixels × Height in pixels) divided by 1,000,000. For example, a 4000 × 3000 pixel photo is 12.00 MP.

Can I check dimensions for a folder of images at once?

Yes. Select multiple files to generate a complete side-by-side specification table and download it as CSV or JSON.
