Exif question

[9mm]

Hello,

I was wondering if the --remove-all option were 100% effective on removing all EXIF data. I know EXIF information can be quite nuanced with lots of versions, etc. Specifically these images will be public online, so to protect user upload I want to remove all GPS/location data, etc.

If it's not a locktight solution I could use exiftool in addition. My follow up question is, if I remove EXIF using exiftool before using jpegoptim, will that affect the ability for jpegoptim to compress effectively (I don't know what things are stored in the EXIF that might help a better optimization result... like color profiles, color space information, etc).

Thanks!
