Full dimension readout
Width, height, exact pixel count, megapixels, and aspect ratio โ everything you'd normally need Photoshop just to check.
Platform size matching

Multi-image compare
Drop up to 8 images at once to compare file sizes, dimensions, and formats side-by-side. Great for QA-ing export batches.
