The input is the base64 text of a ZIP archive: the page reads your local file and base64-encodes it, while the wasm side only parses.
Frequently asked questions
Is my archive uploaded?
No. The page reads and encodes the file locally and the parsing runs in browser WebAssembly.
Are encrypted archives supported?
Encrypted entries are listed and marked encrypted; their contents are never decrypted.
Which compression methods work?
ZIP store and deflate. Entries using bzip2, lzma or zstd are still listed, but not decompressed.
