EnglishWhat file size and formats does unzip-online.com support?
Updated
unzip-online.com accepts .zip and .rar archives and supports files up to 200MB. It is a browser-based service, so you don't need WinZip, WinRAR, or any other installed software to extract the contents. The site states the service is free to use, and uploaded files are deleted after 24 hours.
Supported formats
| Format | Supported | Notes |
|---|---|---|
| .zip | Yes | Standard ZIP archives |
| .rar | Yes | RAR archives, including the common case where WinRAR isn't installed on the machine you're using |
| Other formats | Not stated | The site only lists .zip and .rar, so don't assume 7z, tar, or gz will work |
File size limit
The maximum archive size is 200MB. That limit applies to the file you upload, not to the total size of the files after extraction. A highly compressed archive under 200MB can still expand into a much larger set of files.
What this means in practice
The 200MB ceiling and the two-format support make the service a fit for everyday tasks, for example:
- Opening a .rar file on a school or office computer where WinRAR isn't installed
- Extracting a .zip of documents, images, or a small project folder on a machine where you can't install software
- Checking the contents of an archive before deciding whether to install a dedicated tool
It is not the right tool for large archives (over 200MB), for formats other than .zip and .rar, or for repeated bulk extraction where a desktop utility would be faster.
How to use it
- Open unzip-online.com in your browser.
- Upload your .zip or .rar file (must be 200MB or smaller).
- Wait for the site to process the archive.
- Download the extracted files.
No installation step is involved at any point.
Points to keep in mind
- Size: Files above 200MB are outside the stated limit, so plan to use another method for those.
- Format: Only .zip and .rar are listed. If your archive is another type, this service isn't the answer.
- Retention: Uploaded files are deleted after 24 hours, so download your extracted files within that window.
- Privacy: The site says uploaded files can only be viewed by you, but as with any upload service, avoid sending sensitive or confidential archives unless you're comfortable with a third-party server handling them.
