This evening I started browsing the Web in search of a simple image tool that could be used to quickly remove exif data from JPEGs. A few links later I came across SmallImage. It’s a nice batch JPEG processing tool and can indeed remove exif data very easily. Note that it is capable of doing much more, but so far I’ve only used it for this one task.
SmallImage is donationware and available for OS X (a Snow Leopard version is available).
