This is image compression, which uses visual tricks, not simple binary file compression

Isn't a JPEG already compressed.
I'm confused.

The service is taking an encrypted image and compressing it without decrypting it

What would you use this for?

As a technological demonstration of homomorphic encryption and its benefit.

Compressing images into jpeg without anyone else ever seeing them.
I personally would prefer something like Homomorphic encryption for say sql queries on a database that the server can never read.

There's no information in the repo, but I suppose this means jpeg compression of an encrypted image without decryption, right?

Yes. Homomorphic encryption means that you can do math to the encrypted file to produce a new encrypted file. The operator doing the math cannot read either version, but the owner of the original file can.

Without anyone ever seeing them?

TIL you can get on the front page of HN without a README, explanation of what your project does, no commits in 3 years and less than a dozen stars.
Amazing...
"Compression" and "Encryption" seem like two words I wouldn't expect in the same sentence.
Wouldn't you compress the file independently ... regardless of anytype of encryption (homomorphic or not).
