What it does
ImageSizeChecker checks the width, height, aspect ratio and file size of up to 100 images in one drop. It then tells you which images pass or fail the spec you need. Pick one of the built-in platform presets, or enter your own dimensions.
Why it exists
Most image size checkers stop at reporting dimensions. Designers, marketers and sellers usually need more than numbers. They need to know if an image meets the platform requirement. That pass/fail verdict is the core of this tool.
How it works
The tool reads image dimensions directly from file headers, entirely inside your browser. Your images never leave your device, so there is nothing to upload and nothing to wait for.
