Image Dimensions Checker

See all your image dimensions in one table

Websites, marketplaces and forms often require specific pixel sizes. The Image Dimensions Checker lists the width and height, megapixels, file size and orientation (landscape, portrait, square) of every selected image in a single table.

Aspect ratio and real format

For every image the tool calculates the simplified aspect ratio (e.g. 3:2) and the nearest standard ratio (16:9, 4:3, 1:1 and so on). It also detects the real format from the file's bytes rather than its extension, so you notice files with a wrong extension.

Batch and private

Drop dozens of images at once. All reading happens in your browser.

1. Drop one or more images into the upload area.
2. Review width, height, ratio and megapixels in the table.
3. Check the orientation and real file format columns.
4. Move on to the resize or crop tools if needed.
