I understand it’s to save file space, but like…how?
Follow-up: If you have to compress a photo to save on file size (when emailing, for example) couldn’t it just send essentially a text file on how to uncompress it back to its original size and quality? (ex. “Set the resolution to XxY and add X color at Y pixels”)
Thank you!

Which is why data lacking any patterns (such as random data or already compressed data) can not be compressed any further.
