🗃️ZIP Content Viewer

See what’s inside a ZIP file as a folder tree — names, sizes and dates — without extracting it. Pull out just the files or folders you need.

Your ZIP file is never sent to a server (analyzed in your browser)

How to use

Choose the ZIP file, or drag it onto the box. Its contents appear as a folder tree without extracting anything.
Click a folder to expand or collapse it. Each folder shows how many files it contains and their total size.
Use "Extract" to save a single file, or "Extract folder" to save a whole folder as a new ZIP.
Type in the filter box and press "Save shown files as ZIP" to save just the matching files.

How it works without extracting

Every ZIP file ends with a table of contents that lists each file’s name, size and location. This tool reads only that table, so nothing needs to be extracted and even multi-gigabyte ZIPs list instantly.

Extracting a whole folder

"Extract folder" saves a new ZIP with that folder at the top level. The data is copied as-is, without decompressing or recompressing, so even large folders are quick and nothing about the contents changes.

File names in the new ZIP are written as UTF-8 (with the UTF-8 flag), so names that looked garbled extract correctly on both Windows and Mac, and the paths become shorter by the levels above the folder.

If file names look garbled

ZIPs made on different systems store file names in different encodings, which can turn names into gibberish elsewhere. This tool detects the encoding for each file (the UTF-8 flag, the UTF-8 name that 7-Zip and others store, then legacy encodings). If names still look wrong, pick another option under "File name encoding".

If a ZIP won’t extract on Windows (paths too long, invalid characters and so on), use Fix a ZIP That Won’t Extract to get a ZIP that does. For more on the causes, see “ZIP Won’t Extract? Fix “Compressed Folder Is Invalid” and “Path Too Long””.

FAQ

Is my ZIP uploaded to a server?

No. Reading the ZIP and extracting files all happen inside your browser.

Does it work with large ZIP files?

Yes. Listing reads only the table of contents, so even multi-gigabyte ZIPs appear instantly. Extracting reads only the files you choose.

Can it open password-protected ZIPs?

You can see the list of contents, but encrypted files can’t be extracted.

What about ZIPs inside a ZIP?

An inner ZIP is shown as a single file. Extract it, then open it in this tool again.

A ZIP won’t extract on Windows.

Common causes are paths that are too long, characters Windows doesn’t allow, or an incomplete download. Fix a ZIP That Won’t Extract diagnoses and fixes these. For more on the causes, see “ZIP Won’t Extract? Fix “Compressed Folder Is Invalid” and “Path Too Long””.
