I feel a warning is appropriate for JPEGs. Removing EXIF data would definitely not be considered lossless by most photographers.

Same goes for comments in all file formats.

Neat idea but I'd be happier to use it if I knew it was an unqualified benefit rather than having to think about whether it might strip data I need.

Thanks for being the first one to comment. I understand EXIF is important to photographers.

The initial goal of this tool is to reduce software release size. Most of the formats it supported for now are likely to be part of a software. Software don't need comments, only human needs them.

Maybe I'll add an option to keep EXIF and comments later.
