How to Use the RAR Viewer Online

RAR Viewer opens a .rar and lists what is inside without WinRAR, 7-Zip or any install. It reads both RAR 4 and RAR 5 headers and shows every entry with its size, whether it is encrypted, the total uncompressed size and how much smaller the archive is. Use it to check that a RAR someone sent you contains what they said before you go looking for a tool to unpack it.

Lists what is inside a RAR archive without WinRAR. RAR is a proprietary format with a free decompressor and a licensed compressor, which is why plenty of software can open one and very little can create one.

No software to install Free Works on any device

Why Use File and Archive Tools?

A ZIP from a colleague, a download with no extension or a folder full of badly named files can stop work for a while. These tools unpack, identify, hash and rename files inside your browser, so nothing is uploaded to find out what it is.

“Know what a file is before you open it.”

Archives opened without software
Downloads checked with hashes
Duplicate files found
Big files packed smaller

Unknown files identified
Files renamed in bulk
Folders compared quickly
Contents never leave your computer

Best Times to Unpack or Check a File

Tidying a messy downloads folder
Emailing a folder of documents

Tips and Good to Know

Listing is all it can do. To unpack, use 7-Zip on Windows, The Unarchiver on a Mac or unrar on Linux.
A password does not stop the listing, but encrypted entries are marked and cannot be checked any further.
For ZIP, TAR or 7z, Archive Viewer handles those formats and can extract ZIP and TAR as well.

Frequently Asked Questions

Answers to common questions about this tool.

Do I need to install anything to use the RAR Viewer?

No. RAR Viewer runs entirely in your browser — there is nothing to download, no extension and no desktop program. It works the same on Windows, macOS, Linux, Android and iPhone.

Is it safe to use the RAR Viewer online?

Safer than the usual alternative, yes. Most online tools upload your file to a server you know nothing about, where it sits until someone deletes it. Here the file never leaves your device — the processing happens in the page itself, so there is no server copy to leak, retain or sell.

What is a checksum and why check one?

A checksum is a short code worked out from a file’s contents. If your copy gives the same code as the one the publisher lists, the file arrived complete and unchanged.

Is there a size limit in RAR Viewer?

It depends on your device rather than on the site. Everything is processed in memory in the browser, so a computer handles bigger archives and folders than a phone does.

Is RAR Viewer free to use at work?

Yes. It is free for personal and work use with no account. Because files stay on the machine, it also fits workplaces that do not allow uploading documents to outside sites.
