How to Open RAR Files Online
You can look inside — and sometimes extract — a RAR file in your browser without installing anything. Here's what that route can and can't do.
Get an archive tool for your computer
Download the installer and start opening RAR, ZIP and 7z archives in a few minutes.
Browser-based archive tools generally fall into two categories: ones that upload your file to a server to process it, and ones that process it locally in your browser without ever sending it anywhere. That distinction matters if the archive contains anything sensitive.
What browser-based options can do
- List the files inside an archive without fully extracting them.
- Extract small archives, depending on the specific service and any size limits it enforces.
- Work without installing software, useful on a locked-down or shared computer.
Upload considerations
Our local inspector: no upload
RareExplorer's archive inspector parses an archive's headers directly in your browser, with nothing sent to a server. It lets you see what's inside a RAR, ZIP, or similar archive — file names, structure, and basic metadata — without uploading it anywhere. It inspects rather than fully extracts or converts the archive.
When to install software instead
- You need to fully extract a large archive rather than just look at what's inside.
- You need to repeatedly open archives and want the convenience of a context-menu integration.
- The archive is password-protected and the online tool doesn't support entering one.
- You want to create new archives, not just read existing ones.
If you decide to install something, see WinRAR alternatives for free options on both Windows and Mac, or how to extract RAR files without WinRAR for the no-cost route on each platform.

Frequently asked questions
Is it safe to open a RAR file online?
It depends on the tool. Ones that upload your file to a server introduce more exposure than one that processes the archive locally in your browser, like our [archive inspector](/tools/archive-inspector).
Can an online tool extract a password-protected RAR file?
Support varies by service; many browser-based tools have limited or no support for entering a password, in which case a desktop tool is more reliable.
Does the archive inspector extract files?
No, it inspects the archive's headers and structure locally in your browser. For full extraction, use a desktop tool as described in [how to extract a RAR file](/how-to-extract-rar-file).
Is there a file size limit for online RAR tools?
Most browser-based services impose some size limit, which varies by provider; very large archives are usually better handled by installed software.
