Frequently asked questions
Why is there no .7z option?
There's no browser API or lightweight WASM encoder for 7-Zip's LZMA format that we're comfortable shipping — ZIP and TAR/TAR.GZ cover the vast majority of use cases and are fully supported.
Does ZIP here compress as well as desktop tools?
Yes — it uses the same DEFLATE algorithm at level 6, close to typical desktop ZIP defaults.
