What is unzip-online.com?

Updated

unzip-online.com is a browser-based file extraction tool for .zip and .rar archives. It is aimed at situations where you cannot install WinZip or WinRAR — for example, a school or office computer with restricted software — and it accepts files up to 200MB. You upload an archive, the site extracts it, and you download the uncompressed files. No software installation is required on your side.

What it does

The site handles two of the most common archive formats:

  • .zip — the standard format produced by Windows, macOS, and most "compress" options in file managers.
  • .rar — a format that normally requires WinRAR or a compatible extractor.

According to the site, you can unzip .zip and unrar .rar files "for free without having winzip/winrar installed." That makes it a fallback when the machine you are using has no extraction software and you cannot install any.

Key limits and conditions

Item Detail
Supported formats .zip, .rar
Maximum file size Up to 200MB
Software required None — runs in the browser
File retention Uploaded files are deleted after 24 hours
Visibility Uploaded files "can only be viewed by you"

The 200MB ceiling is the main practical constraint. If your archive is larger, this tool will not accept it, and you would need a desktop extractor or a service with a higher limit.

When it is a good fit

Use unzip-online.com when:

  • You are on a shared, locked-down, or borrowed computer where you cannot install WinRAR or WinZip.
  • The archive is 200MB or smaller.
  • You only need to extract once and do not want to set up software for a single task.

It is less suitable when:

  • The archive exceeds 200MB.
  • You are handling sensitive material and prefer not to upload it to a third-party server at all — even with the stated 24-hour deletion, the file leaves your machine.
  • You need to extract many files repeatedly, where a local tool is faster and avoids upload/download time.

How to use it

  1. Open unzip-online.com in your browser.
  2. Upload your .zip or .rar file (must be 200MB or under).
  3. Let the site extract the archive.
  4. Download the uncompressed files it presents.

The expected result is the contents of your archive, downloaded to your device without any installation step.

Points to keep in mind

  • Upload time counts. A 200MB archive still has to travel to the server and the extracted files have to come back, so a slow connection can make this slower than a local extractor.
  • 24-hour deletion is a stated policy, not a guarantee you control. If the contents are confidential, treat uploading as a disclosure decision.
  • Password-protected archives are not mentioned in the site's description, so do not assume encrypted .zip or .rar files will work.
  • Format coverage is limited to .zip and .rar; other formats such as .7z or .tar.gz are outside what the site advertises.
