ZIP archive content viewer
The archive is read entirely in your browser using JSZip - it is never uploaded anywhere, and no file contents are extracted or previewed, only the listing.
What it is for
Checking what is actually inside a ZIP file before extracting it - the file list, folder structure, and each entry's uncompressed and compressed size - without unpacking it anywhere. Useful for a ZIP received from somewhere you would rather not extract blindly, or simply to confirm a download contains what it is supposed to before committing disk space to it.
What is shown
Every entry's path within the archive, whether it is a file or a folder, its uncompressed size, its compressed size, and the resulting compression ratio - so an archive that claims to be a small download but unpacks to something enormous is visible before that happens, not after.
What this does not do
It does not extract file contents or preview what is inside individual files, and it cannot open a password-protected archive's file list on every ZIP format variant - encryption metadata varies enough between tools that some protected archives may show only partial information. For extracting files themselves, see the ZIP file extractor.
Privacy
The archive is read entirely in your browser using JSZip - it is never uploaded anywhere.
