Useful information about Image Dimensions Checker.

Which image formats can it inspect?

The checker supports bounded JPG, PNG, WebP, GIF and BMP headers. It does not claim AVIF, SVG or TIFF support.

Does checking dimensions decode the full image?

No. It reads validated header fields, which avoids creating a full-size canvas or uploading the file.

What information does it show?

It reports width, height, detected format, file size and aspect ratio.
