Image Information Inspector
Image Information Inspector
Read decoded dimensions, file size, format and alpha presence.
Prepared files
Preview, inspect and downloadChoose an image and prepare it to see your result here.
Downloads are generated files, not links to stored uploads. Batch and layout tools can return several files.
An image's extension alone does not explain its decoded dimensions or format.
Inspect the source before deciding whether it needs resizing, conversion or compression.
How to use Image Information Inspector
