Exifpurge.com. A portable Windows app to remove all exif data from multiple photos.

Cool.

Can anyone recommend a linux tool for removing exif data from images and metadata from pdfs?

For jpg: jhead -purejpg, exiftool looks like it only has "remove this specific kind" (like -gps:all= .)

(The more boring use case for this: putting images up on a web page - if you use jhead -autorot to correct the orientation, then the browser sees the metadata and rotates it again...)

exiftool is the standard. Should be in your distros repo...
