Can't delete metadata from tif, svg images

I am new to exiftool and new to this forum.  I am simply trying to remove all metadata from all images in a given directory.  I am getting the following two messages:

"Warning: [minor] Can't delete IFD0 from TIFF image"    and   "Error: ExifTool does not yet support writing of SVG images"

Is there any way I can get around this?  If not is there any other tool that will remove metadata from all images?

Thanks!

Hi,

Until Phil jumps here (with more precise info)...

From my experience, you can't delete all metadata from TIF files... because that would (somehow) mean, deleting image data itself. That means (if I'm right), some metadata tags must be kept inside TIF -but I didn't checkout which of them.

No idea about SVG -sorry.

Greetings,

Bogdan

Thank you for the response.  That is fine as it deleted everything else.  I guess the only question left is about the SVG.  We only have a few SVG images but still need to make sure the metadata won't be searchable once they are in PDF format.

You can use exiftool to delete tags individually from a TIFF
image, but only the ExifIFD is removed when performing
a group delete (ie. "-all=") on a TIFF image.  This results
in some meta information tags remaining in IFD0 which
must be deleted individually.  IFD0 can't be removed because
it contains the image.

ExifTool doesn't write SVG images, but these types of images
are XML based, so you can remove the meta information
with any XML or text editor if you really need to.
