I have noticed when I save a picture from email, Facebook, or text thread it shows where the photo was saved from. I don’t want this information shared when I forward the picture. How do I stop it without deleting the other metadata, like location and date.
With xattred.app strip "com.apple.metadata:kMDItemWhereFroms" flag or Edit the URL.

Via the Terminal check extended attributes (you might have to install xattr if macOS does not have it built-in):
xattr image.jpg
xattr -l image.jpg
Remove one extended attribute:
xattr -d com.apple.metadata:kMDItemWhereFroms image.jpg
Remove one extended attribute from all files in the current folder:
xattr -rd com.apple.metadata:kMDItemWhereFroms .
Remove all extended attributes:
xattr -c a.jpg
Remove all extended attributes recursively in the current folder:
xattr -rc .
If the photo is in your Photos library just export it as a JPEG (not as an original) and it will lose the source info.
The reason for the size difference is that the original was Apple's HEIC file which was much smaller than the resulting JPEG file.
Stop showing the App from which photos are saved
