Well, it’s sort of possible to compress large things into small sizes. But I don’t think it would work for this situation.

There are things called “.zip bombs”. Where an otherwise small file, when unpacked, can take up a large amount of space.

A famous example of a zip bomb is titled 42.zip, which is a zip file of unknown authorship consisting of 42 kilobytes of compressed data, containing five layers of nested zip files in sets of 16, each bottom-layer archive containing a 4.3-gigabyte file for a total of 4.5 petabytes of uncompressed data.
