This is when the little known utility developed by David Crowell named jStrip comes in handy. jStrip removes optional data chunks, such as Exif Data or Photoshop thumbnails, from the JPEG’s. By doing so it usually shaves around a half-dozen kilobytes off of the image size.

I originally began using jStrip to prevent an incident similar to what happened to Cat Schwartz in 2003. Whilst you won’t catch me naked in any of my Exif thumbnails, there is obviously a bit of risk associated in uploading images straight from your image-editing software to your website.

For that matter, jStrip is a great tool for removing unexpected materials and reducing file-size.
