Hey, I am the creator of https://www.photopea.com and if a user decides to publish their work, it compresses PSD files (inside a browser) and sends them to the server for storing. Right now, we have about 2 TB of files. I use the DEFLATE compression which I fully implemented myself (compressor and decompressor, inside a library called UZIP.js).

I wish I could use something better :D but it must be implemented in Javascript to run inside a browser, and the library should not be too large (mine is about 8 kB ZIPped). I would love to switch to ZSTD once someone implements a compressor in Javascript that is under 40 - 60 kB. Or do you think that bzip3 could be re-implemented easily in JS using some AI?

I really admire you for being so smart at such a young age :) I wish you best of luck in your scientific career! I visited Warsaw this year, but I am not sure if that is where you are from :D
