Can it open password-protected ZIP files?

No. Encrypted archives require the password to decrypt their contents, which this in-browser tool does not handle. Use a desktop tool for those.

Does it keep the folder structure?

Yes. Nested folders are preserved in the file paths, and the Download all option rebuilds the same structure inside a new ZIP.

Are my files uploaded anywhere?

No. Everything is processed in your browser with WebAssembly and JavaScript — your files never leave your device.

What is a ZIP archive?

ZIP is the most common archive format — a single .zip file that bundles many files and folders together with lossless compression. It is what most download links, email attachments, and exports arrive as.

Why extract in the browser?

Desktop unzip tools work, but uploading a ZIP to a website to open it is a privacy risk. Convertur unpacks the archive locally so confidential documents, source code, or design files never touch a server.

How extraction works

The ZIP central directory is read in the browser and each entry is decompressed with the DEFLATE algorithm. You get a full file listing with sizes, per-file downloads, and a one-click re-bundle of everything as a fresh ZIP.

Quality and compatibility

Standard DEFLATE and stored ZIP entries are supported, including nested folders. Encrypted (password-protected) archives cannot be opened without the password and are not supported.
