Your friend have just sent you an email containing a file attachment. Apparently, the file is an archive file in the ZIP format and you have no unzip tool installed on your computer. If you have to open the archive right away now, you can use online unziper tool to unpack the archive, without having to install an unzipper app first.

Some online unzipper tools has the capability to open password-protected archive files. Some are not. In addition to ZIP, most online unzipper tools are also capable of extracting other archive file formats, including RAR.

If you are on the scenario like I mentioned above, below is the list of the tool you can use.

1. B1 Online Archiver

B1 Online Archiver is one of the best tools to extract an archive file online. Not only you can extract an archive file in the ZIP file, you can also use it to extract other archive formats like RAR, JAR, 7z and so on. B1 Online Archiver has a capability of extracting a password-protected archive. It takes only 2 steps to extract archive files using this tool. In addition to being able to use B1 Online Archiver online, offline version is also available for Linux, Windows, macOS and Android.

2. Unzip-online.com

If you have a password-protected archive file and don’t know the password, try to use Unzip-online.com. I have tried it and worked. At the time of writing this tool only supports two archive file formats; ZIP and RAR. It also only takes two steps to extract an archive file using this tool. Once extracted, your files will only be available for 24. Afterwards, your files will be deleted from the Unzip-online.com server. You can extract up to 200 MB of file using this tool.

3. ezyZip

ezyZip is a pure online unzipper tool. This tools (at the time of writing), has no capability to open other archive file formats. It also has no capability to extract a password-protected ZIP file. However, if you want to give it a try, then there is no bad at all. In addition to extract, you can also use this tool to create a ZIP file.

Extract.me is probably the best online unzipper tool out there. Not only you can use it to extract an archive file in the ZIP format, but also other formats including RAR, TAR, 7z and so on.

5. Funzip
