Zstandard spread fast through modern backends, package systems and data tooling, and files escape those contexts onto ordinary machines with no zstd anywhere. Conversion closes the gap: the zst layer decompresses, an inner tarball unpacks if present, and a plain ZIP emerges holding the same tree. The recipient's machine needs nothing newer than the nineties. Decompression is quick, zstd's specialty, and everything stays in the browser.
Questions
Where do .zst files usually come from?
Backup systems, package managers and data pipelines that adopted Zstandard for its speed; the files then travel to machines that never did.
Is decompression slow?
No, zstd decompresses very quickly; the rebuild into ZIP is the bulk of the work.
Local processing?
Yes, in-memory in the browser.
