What information does it show?

For each image: file name, dimensions in pixels, format (JPEG, PNG, WebP, GIF, AVIF and more), file size, and aspect ratio.

How is the aspect ratio calculated?

Dimensions are reduced to their simplest ratio, like 16:9 or 4:3. Unusual sizes show a decimal ratio such as 1.33:1.

Does it change or compress my images?

No. This is an inspection-only tool. Your files are read, never modified, and nothing is downloaded unless you want it.

Can I check many images at once?

Yes, drop up to 50 images and they all appear in one table, perfect for auditing a folder before upload.

Are my images uploaded to a server?

No. Everything is read locally in your browser. Your files never leave your device.

Why do dimensions matter?

Platforms reject or downscale wrong-sized images. Checking first saves you from blurry uploads and failed form submissions.
