How it works

The tool reads the archive’s table of contents, shows the list of what it contains, and unzips a file only when you ask. Unzipping relies on a function built into the browser.

Each extracted file is checked against its checksum, the one recorded in the archive. A damaged archive is flagged.

What the tool can and can’t do

It opens standard zip archives, including those created by Windows File Explorer or the Finder, with their folders and accented names.

It reads classic zip archives and zip64 archives, the ones larger than four gigabytes or holding more than 65,535 files. A password-protected archive opens with its password, whether it is encrypted with AES, like the ones made by our protection tool, by 7-Zip or by WinRAR, or with the old zip encryption. It cannot open RAR and 7z archives, which are other formats with their own algorithms: it tells you so plainly rather than failing silently.

Frequently asked questions

Is my archive sent anywhere? No. You can check for yourself in thirty seconds: here is how.

Can I extract everything at once? Yes. Everything is repacked into a single zip, made on your phoneyour tabletyour computer, with one folder per original archive. A single download, whatever the number of files. You can also download a specific file from the list.

Are folders kept? Yes, in the zip produced: each original archive becomes a folder and the internal paths are kept. A file downloaded on its own, however, lands flat in your usual folder, since a browser isn’t allowed to create folders on your disk.

Does a large archive work? Yes; the table of contents is read without loading the whole file.

What about a .docx or .xlsx file? Technically they are zip archives, and the tool will open them. To read a Word document comfortably, use the dedicated tool instead.
