Lightroom - How To Remove Metadata From My Images

If you want to remove metadata from your images, I am making an educated guess, that it is because you don't want other people to see it. Therefore, whilst in theory, you can go ahead and directly remove the metadata from the image in the Metadata panel, this doesn't necessarily make sense. Doing this potentially makes the image harder for you to find, later on, e.g. if you are searching for it. I, therefore, recommend that people remove the metadata when they export an image, but leave it intact in the original file.

During the export process, there is a Metadata section. You can choose to remove all metadata, keep all metadata, or selectively remove elements like the person and location info.
