Why can’t I convert a ZIP back into a RAR file?

Creating RAR archives is legally restricted to licensed WinRAR software — the compression format is proprietary to win.rar GmbH, and no free or open-source tool can legally produce new RAR files. Reading existing RAR files, which this tool does, is a separate and much more open capability.

Does this work with password-protected RAR files?

No. Encrypted RAR entries require the original password to decrypt, and this tool doesn't currently support entering one — attempting to convert an encrypted archive will show an error instead of a broken output.

Will the converted ZIP have the exact same files as the RAR?

Yes — every file, its original name, and its folder structure inside the archive are preserved exactly when repackaged into the ZIP.

Does the ZIP end up larger or smaller than the original RAR?

It varies. RAR and ZIP use different compression algorithms, and RAR is often slightly more space-efficient, so the resulting ZIP may be a bit larger than the original RAR for the same files — though both remain much smaller than the uncompressed originals.

Why would I need this instead of just installing WinRAR?

If you're on a Mac or Linux system without RAR support built in, or you just received one RAR file and don't want to install dedicated software to open it once, converting to ZIP — which every OS opens natively — is faster than installing an archive tool.

Is there a size limit on the RAR file I can convert?

No hard limit is built into the tool. Since everything processes in your browser's memory, very large archives may be slow or hit your browser's memory ceiling, but there's no server-imposed cap.

Is my RAR file uploaded anywhere during conversion?

No. The entire read-and-repackage process happens locally in your browser using WebAssembly — nothing is sent to a server.

What RAR versions does this support — RAR4, RAR5, or both?

The underlying libarchive engine supports both RAR4 and the newer RAR5 format, covering archives created by recent and older versions of WinRAR alike.

Does this modify or delete my original RAR file?

No. The tool only reads the archive to generate a new, separate ZIP file — your original .rar file on disk is left completely untouched.

Can I convert a RAR that contains other archives inside it?

Nested archives (a ZIP or another RAR inside this RAR) are extracted as regular files into the new ZIP, not automatically unpacked further — you’d need to open that inner archive separately afterward.

What is RAR to ZIP?

RAR is a proprietary archive format owned by win.rar GmbH — reading a RAR file is openly documented and widely supported, but CREATING one legally requires a licensed copy of WinRAR or its SDK, which is why free online tools (including this one) can open RAR files but can't produce new ones. This tool reads your RAR archive's contents using libarchive compiled to WebAssembly, then repackages everything into a standard ZIP file — a format with no licensing restrictions that every operating system can open natively.

The practical effect is you get a drop-in replacement: all your files, same names, same folder structure, just in a format that doesn't require WinRAR, 7-Zip, or any other software to open. This matters most for Mac and Linux users, since RAR support isn't built into either operating system the way ZIP is, and for anyone who received a RAR archive but doesn't want to install dedicated extraction software just to open it once.

One limitation worth knowing upfront: password-protected RAR archives can't be processed. The underlying library can read standard RAR compression, but encrypted entries require the password to decrypt, which this tool doesn't currently prompt for — attempting to convert an encrypted RAR will fail with an error rather than silently producing a broken ZIP.

How It Works

The RAR file is read into browser memory and passed to libarchive (compiled to WebAssembly), which understands the RAR format's internal structure well enough to list and decompress its entries — this is read support only, not RAR's compression algorithm reimplemented, since that would require a license from win.rar GmbH. Every file and its original folder path is extracted into memory, then handed to JSZip, which compresses and repackages everything as a standard ZIP archive for download.

How to Use

Upload your RAR file

Drop a .rar archive onto the upload area, or click to browse for it.

Wait for processing

The archive is read and its contents are listed in your browser.

Download the ZIP

A new .zip file containing everything from the RAR is generated and downloaded automatically.

Open it anywhere

The resulting ZIP opens with any operating system’s built-in archive tool — no RAR software needed.
