How to Extract RAR Files Without WinRAR (Any Device)
By the UtilityNest team · · 5 min read
Your cousin finally sent the wedding photos, all 312 of them, as wedding-final.rar. You are on a Chromebook. You double-click and the Files app shrugs. A search for "open rar" offers you a 40-day trial of WinRAR and a lot of download buttons that look a little too eager.
RAR is a popular archive format, especially for big photo sets, game mods and files passed around forums. Opening one does not require WinRAR, and it does not require installing anything at all.
The short version: drop the file onto Extract RAR in your browser. Browse what is inside, preview it, and download one file, a selection, or everything. RAR4 and RAR5 both work, and so do password-protected archives if you know the password.
Extracting a RAR in your browser
- Open Extract RAR and drop in the .rar file (a self-extracting RAR .exe works too).
- If it is password-protected, type the password and click Unlock.
- Browse the folder tree, search by file name, and click the eye icon to preview images or text.
- Download single files, tick several and download them as a ZIP, or in Chrome and Edge use Extract to a folder to write everything straight to your disk.
The archive is read on your device by the official UnRAR decompression code, compiled to run inside your browser. It handles real RAR4 and RAR5 archives, including solid archives and files packed with RAR's strongest settings. Nothing is uploaded, which is not true of many sites that promise to "extract RAR online".
A worked example: the wedding photos
wedding-final.rar, 1.4 GB... which is a bit much for a browser. Your cousin re-sends it as two smaller archives of about 700 MB each.
- Drop the first one in. The engine (about 200 KB) loads the first time, then the folder tree shows
Ceremony,ReceptionandPortraits. - Preview a couple of photos with the eye icon to make sure it is the right set.
- In Chrome, click Extract to a folder and pick
Downloads/Wedding. Repeat with the second archive.
A file nothing on the Chromebook can open, plus a pile of sketchy download links.
312 photos in a folder, original names and subfolders intact, nothing installed.
Only need a handful of files from a big archive? Search by name and download just those. You do not have to unpack the whole thing to get three photos out.
Password-protected RAR files
Enter the password and click Unlock. If the creator also used WinRAR's Encrypt file names option, you will not see the file list until the password is right; once it is, the list appears. The password is used only in that browser tab. And to be clear, the tool does not guess or crack passwords: if you do not have it, ask the person who sent the file.
Multi-part RAR sets
Big archives are sometimes split into .part1.rar, .part2.rar and so on. In the browser, each part is read on its own: files that sit entirely inside the part you open can be extracted, but a file that continues into the next part needs all the parts together in desktop software such as 7-Zip or WinRAR. If you get to choose, ask the sender for one archive per batch instead of one split archive.
Other ways to open RAR files
| Device | Without WinRAR |
|---|---|
| Windows 11 | File Explorer opens RAR natively (version 23H2 and later) |
| Windows 10 | 7-Zip (free), or the browser tool |
| Mac | Keka or The Unarchiver (free), or the browser tool |
| Chromebook | The browser tool |
| iPhone and Android | The browser tool in Safari or Chrome |
Is it safe to open a RAR?
Opening and browsing an archive does not run anything. The risk is in what you do next. Be wary of archives from strangers, and especially of any .exe, .bat or .scr file inside something that was supposed to be photos or documents. Previewing first is a good habit: if a "PDF" turns out to be invoice.pdf.exe, delete it.
Sending files back? Use ZIP
If you need to send files to someone else, ZIP is the friendlier choice: Windows, macOS, iOS and Android all open ZIP files without extra software. Create ZIP packs files or a whole folder in your browser.
When the RAR will not open
"This is not a RAR file"
The extension may be wrong. The archive tools here detect the format from the file itself, so try dropping it on Unzip, which also opens ZIP, 7z, TAR and GZ files. A download that stopped halfway is another common cause: compare the file size with what the sender expected.
"Wrong password"
RAR passwords are case-sensitive. Check Caps Lock, and watch for a space copied along with the password from an email or chat.
A file inside is damaged
Archives get damaged in transit more often than you would think, especially large ones sent through chat apps. If a file will not extract or comes out broken, try opening the archive in 7-Zip, which reports exactly which files fail their checksum, then ask the sender to re-upload it, ideally through a different service.
It is very slow on a phone
Big solid archives need a lot of memory to decompress. A laptop or desktop browser copes much better than a phone with the same file.
Quick answers
Does it support RAR5?
Yes. Both RAR4 and RAR5, including solid archives.
Is my RAR file uploaded?
No. It is decompressed in your browser and never leaves your device.
How big a RAR can I open?
That depends on your device's memory. Archives of a few hundred megabytes are comfortable on a laptop; for multi-gigabyte archives, desktop software is the safer bet.
What about ZIP, 7z and TAR files?
The same engine opens those too. Unzip handles ZIP files, including AES-encrypted ones.
