Why do dimensions differ from what my camera claims?

Orientation flags rotate display without changing stored pixels. Decoded dimensions here are the true raster size.

Does it read EXIF too?

No — this covers container facts. Pair with the EXIF viewer for camera metadata.

What counts as portrait vs landscape?

Pure dimension comparison (w>h landscape, w<h portrait, equal square) — orientation flags ignored by design.

About Image Info

Report any image’s dimensions, megapixels, format, size, orientation, and aspect ratio.

Select an image to read its decoded dimensions, MIME format, byte size, megapixel count, orientation, and aspect ratio — the facts upload validators check.

Decoding proves validity too: a corrupt file fails here exactly where uploaders would choke. Files stay in your browser.

Where it is used

Checking upload requirements, debugging layout shifts, verifying exports, and triaging "why won’t this upload" cases.
