Why are you surpried? It’s actually possible. You just need so much computing power like around 64 GB ram and High End CPU to Pack and Unpack both.

No way media compressed 5x.

Because modern media formats are already compressed by default and have very little redundancy in them.

Was thinking the same thing

Maybe they store images as uncompressed .bmp for some reason
Lichtblitz@discuss.tchncs.de 12 hours ago
bmp should not compress more than other media files. jpeg, png, etc. can compress so much because they are lossy

Png is lossless

You’re right. png can be lossy but that’s uncommon in the wild.

Three files of the same image: A png (15.7MiB), a bmp (28.8MiB) and a bmp.zip (16.4MiB)

The image doesn’t look like a photo. The meme is about porn. Digital images can contain large areas of repeating patterns (uniform color areas for example) that can be compressed losslessly pretty well. Even slight noise from an image sensor can block that kind of compression pretty well.
