Are you sure about this? I usually send images/videos via WhatsApp because, AFAICT, they are sent unchanged (unlike Facebook messenger, for example), and know multiple people who do the same thing.

I never checked the file hashes, though.

Afaik there's a mysterious 'send as file' in WhatsApp that I haven't mastered that will indeed send the files unmodified, but if you just send from your gallery they will recompress.

I generally don't care about my photos THAT much to figure out how to send them completely unmodified.
