The format your operating system will not open

ZIP is built into everything. RAR is not, and never has been, because it is a proprietary format whose compressor is licensed rather than open. Windows and macOS will both show you a .rar file and neither will open it.

So the usual path is to go and find a desktop utility, which for most people means a trial version that nags, or a search result that installs something you did not want. For a single archive somebody emailed you, that is a disproportionate amount of trouble.

Decompression, unlike compression, is freely available: the official unrar implementation is published as source and compiles to WebAssembly. That build is bundled with this page, so opening a RAR here needs nothing more than the browser you already have, and the archive never leaves your machine.

Opening an archive

  1. Drop your .rar file on the box or use Choose a file. One archive at a time.
  2. Click RAR Extractor Online. The archive is read, checked and unpacked in your tab.
  3. If it holds a manageable number of files, you get one download link per file plus a zip of the whole set, named after the original archive. A single file inside comes back on its own, with no zip.
  4. If it holds more than two hundred files, that zip is all you get.
  5. Process another clears the box for the next one.

There is no preview and no file list. Extraction is one action, which keeps the tool simple and means you cannot pull out a single file from a large archive without receiving the rest.

Two limits, for two different reasons

The first is a count. Whenever an archive holds more than one file, the results include one zip of everything alongside the individual download links, so grabbing the lot is a single click. Above two hundred extracted files those individual links stop being useful and become a wall, so the zip is handed back on its own instead. Both halves of that are a user experience decision rather than a technical one.

The second is a memory limit and it is real. Everything has to be held uncompressed in your tab at once, so the sum of every entry’s uncompressed size is checked before extraction begins and an archive over roughly a gigabyte is refused before extraction starts rather than being attempted.

That check is on the uncompressed total, not the archive’s own size. A heavily compressed archive of text can be small on disk and enormous once expanded, which is exactly the case a size check on the .rar file itself would miss.

Passwords and corruption are told apart

A RAR archive can be locked in two different ways, and both are detected.

The whole header can be encrypted, in which case even the list of file names is unreadable until a password is supplied. Or the names can be readable while individual files are encrypted, which is the mode that lets you see what is in an archive without being able to open it. Either way, extraction here is refused, and the message raised internally names the problem and the practical fix, which is re-saving the archive without a password in a desktop tool.

Failures that are not password related are reported as corruption instead. That distinction is made from the library’s own specific error reasons rather than from guesswork, so a truncated download and a locked archive do not produce the same message.

One caveat worth knowing: the shared layout around this tool replaces any error it raises with one fixed generic sentence, so those carefully separated messages do not reach the screen. If an archive is refused, work through the possibilities yourself, starting with whether it is password protected.

Folders come out flat

A browser download writes a file, not a directory tree. There is no way around that, so nested paths inside the archive are flattened to plain file names on the way out.

Where flattening would cause two files to collide, the names are made unique rather than one silently overwriting the other. The zip bundle is built from those same flattened names, so the two routes out of the tool behave consistently.

That does mean the zip is not a way to recover the folder structure. It is a convenience, so you can take everything in one click instead of one link at a time. If the original tree matters, keep the .rar itself and open it with a desktop tool.

Unzip Files is the ZIP equivalent and shares this tool’s naming, bundling and safety limits directly rather than reimplementing them. Zip Files goes the other way and packs files up.

For the other formats that also need software on a fresh machine, 7z Extractor and Tar.gz Extractor cover them. If what came out of the archive is data rather than documents, Excel to JSON and JSON to CSV handle the conversion. The rest is on the dev tools hub.

Frequently asked questions

Do I have to install WinRAR to open a RAR file?

No. Neither Windows nor macOS opens RAR natively, which is the whole reason this format sends people looking for software, but the extraction itself is just code and it runs here in your tab. The unpacking library is a WebAssembly build of the official unrar implementation, bundled with the page rather than fetched from anywhere.

Does the archive get uploaded?

No. The file is read into memory in your browser and unpacked there. That matters more for archives than for most file types, because a RAR is usually somebody's whole project folder, backup or document set rather than a single file, and a free web unpacker that takes an upload is being handed all of it.

Can it open a password-protected archive?

No. Both cases are detected, namely an archive whose entire header is encrypted, so even the file list is unreadable, and one where the names are visible but individual files are encrypted. The refusal reaches the screen as the layout's one fixed generic sentence rather than as a password message, so if an archive is refused, try re-saving it without a password in a desktop tool.

Why is there a zip download as well as the individual files?

Because both are useful. Any archive holding more than one file gives you every extracted file as its own download and one extra zip containing all of them, named after the original archive, so you can take the single file you came for or the whole set in one click. Past two hundred files those individual links stop being a convenience and become a wall, so above that count the zip is all you get. An archive holding exactly one file just gives you that file, with no zip around it.

How big an archive can it handle?

Roughly a gigabyte of uncompressed content, checked against the sum of every entry's real size before anything is extracted. Everything has to fit in your tab's memory at once, so the cap exists to refuse the archive up front instead of crashing the tab, even though the refusal shows as the same generic sentence as any other failure. It is the uncompressed total that matters, not the size of the .rar file itself.

What happens to the folder structure inside?

It is flattened. Browsers cannot write a folder tree from a download, so files from nested directories come out as individual downloads, and names that would collide after flattening are made unique. The zip bundle carries the same flattened names inside it, so it is not a way to get the original tree back either.

Can I see what is inside before extracting?

No. There is no file listing step and no preview, so extraction is all or nothing. That is a real limitation of the single action shape this tool uses. If you only want one file out of a large archive, you will still receive everything.

What does it do with a corrupt file?

Reports that it could not be read and stops. The failure reasons are distinguished internally, so a missing or wrong password is separated from genuine corruption, and an archive containing only empty folders gets its own message rather than looking like a failure. The surrounding layout replaces those specific messages with one generic sentence, so if a file is refused, check first that it is a real, complete, unencrypted RAR.
