ExifCleaner lets you remove privacy-invading information from your photos.
Metadata is information that is part of the image file and contains information about the image itself and the creation of the image. It can set textual information such as title, description, exposure time, ISO value, focal length, and copyright.
Metadata is useful for many reasons. First, it provides the photographer with a great way to learn. When you capture an image and you want to see why it works (or doesn’t), the metadata will help. However, sometimes it’s advisable to scrub EXIF metadata from photos before sharing them. Besides protecting your privacy, removing the metadata reduces the file size.
