Check dimensions and ratios of multiple images
Import a batch of images to instantly get a summary table of their dimensions, aspect ratio, orientation, and file size — handy for checking the consistency of a set of photos before publishing.
How it works
Before publishing a batch of photos on an online store or website, it's useful to check that they all share the same proportions and a sufficient resolution. This tool reads the header of each selected image (without sending them anywhere) to extract the width, height, simplified aspect ratio, orientation, and file size, then presents everything in a table exportable as CSV.
How is the aspect ratio calculated?
The displayed ratio is the width/height fraction simplified to its smallest integer form via the greatest common divisor of the two dimensions (for example 3000×2000 becomes 3:2). This lets you spot at a glance images that don't share the same format within a supposedly homogeneous batch.
What should I do if an image shows an error?
An error appears if the file is not an image recognized by the browser or if the file is corrupted/truncated. The other images in the batch are still analyzed normally; simply remove and replace the failing file if needed.
100% local analysis: your images are read directly by your browser to extract their metadata, and are never sent to a server.
