How to Unzip or Unrar Files With unzip-online.com

unzip-online.com is a browser-based tool for extracting .zip and .rar archives without installing WinZip or WinRAR. It accepts files up to 200MB, requires no software or registration, and deletes uploaded files after 24 hours. It fits situations where you're on a locked-down or shared computer (school, office, library) and can't install extraction software — but it isn't the right choice for archives larger than 200MB or for content too sensitive to upload to a third-party server at all.

What the site supports

The site states it is "ideal for at school/office where winrar/winzip is not available."

Step-by-step: extracting a file

1. Open the site. Go to unzip-online.com in your browser. No download or install step is involved.
2. Upload your archive. Select the .zip or .rar file you want to extract. Keep it at or under 200MB — larger files are outside the stated limit.
3. Wait for extraction. The site processes the archive server-side and returns the uncompressed contents.
4. Download the extracted files. Retrieve the uncompressed files from the results. You don't need to create an account to do this.

Expected result: you end up with the individual files that were packed inside the archive, downloaded to your machine, without ever installing an extraction program.

Things to watch for

• The 200MB ceiling is per file. If your archive exceeds it, you'll need to split the archive before uploading or use a desktop tool instead.
• Upload speed matters. A 200MB upload on a slow connection can take a while, and the extraction only starts once the upload finishes.
• Password-protected archives. The site's description covers .zip and .rar extraction but doesn't state whether encrypted/password-protected archives are handled. If your archive is password-protected, test with a small file first rather than assuming it will work.
• The 24-hour deletion is a retention window, not a guarantee about your data. The site says files are deleted after 24 hours and viewable only by you. If your archive contains confidential material and your organization prohibits uploading files to external services, use a local tool instead — the convenience of no-install extraction doesn't override that policy.

When to use it vs. a local tool

Use unzip-online.com when: you're on a machine where you can't install software, the archive is under 200MB, and the contents aren't sensitive enough to rule out a third-party upload.

Use a local extractor when: the archive is over 200MB, you need to handle password-protected or unusual formats, you're offline, or your files can't leave your device or network under your organization's rules.
