Exif.tools is a simple online tool for viewing the metadata embedded in a photo. You upload an image, and it displays the EXIF data — camera model, lens, aperture, shutter speed, ISO, focal length, date taken, and sometimes GPS coordinates. This is useful for photographers who want to learn from someone else's shot, for verifying whether an image has been edited, or for checking the settings you used in a photo you took a while ago.

It works with JPEG, TIFF, and RAW files from most camera brands. The interface is minimal and the tool is free. There's no account required and no file retention. If you're curious about the technical details behind a photo, this is the fastest way to see them.
