No way media compressed 5x.
Maybe they store images as uncompressed .bmp for some reason
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.
PNG actually uses the same compression algorithm as ZIP (DEFLATE).
Here are the files.
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.
With a picture from Unsplash:
ZIP compression of bmp is worse, but still compresses more than png. Here are the files.
Fascinating. That's much more than I expected. Thanks for taking the time.
Was thinking the same thing
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.
Because modern media files are already compressed by default and have very little redundancy in them.
