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

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:
Three files of the same image: A png (34.5MiB), a png.zip (34.5MiB), a jpg (4.9MiB), a bmp (98.2MiB) and a bmp.zip (65.1MiB)

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.
