How it works

Drop your ZIP file

Any standard ZIP archive.

See what's inside

Every file listed, with all of them selected by default.

Download what you need

One file downloads directly, several come as a new ZIP.

Look inside a ZIP before you extract it

Sometimes you only need one file out of a ZIP archive that contains dozens: a single photo from an export, one document from a folder someone sent you, a particular data file from a larger package. Extracting everything to look for the one file you need wastes disk space and time. This tool lists the contents first, so you can pick exactly what to download.

How it works

Drop the ZIP file and its contents are listed, every file inside it, ready to be selected individually or all at once. Choosing a single file downloads it directly with its original name. Choosing several packs just those files into a new, smaller ZIP for you to download.

Why it stays private

The ZIP file is opened and decompressed entirely in your browser, using your device's own processing power; nothing is sent to a server to be unpacked. That matters for ZIP files containing anything sensitive, and it also means there is no server-side size limit beyond what your own device can handle.

What it does not do

This does not open password-protected ZIP files, since that would require handling the password in a way this tool is not built for. It also does not preview the contents of the files themselves, only lists their names; you need to download a file to open it, and formats such as RAR and 7-Zip use a different structure that this tool does not read. To create a ZIP file instead of opening one, use the ZIP creator.

Frequently asked questions

How do I open a ZIP file without installing software?
Drop it here. Its contents are listed immediately, and you can download the files you need directly from your browser.
Can I extract just one file from a ZIP?
Yes. Untick everything except the file you want and press download; that single file downloads with its original name.
Does it work with password-protected ZIP files?
No, encrypted ZIP files are not supported.
Is there a size limit?
ZIP files up to 300 MB are accepted. Larger files depend on how much memory your device has available.
Can I preview what's inside the files?
No, only the file names are listed. Download a file to open and view it.
Is my ZIP file uploaded to a server?
No. It is opened and read entirely in your browser.
