Why convert RAR to ZIP
RAR is a popular archive format, but it's proprietary, and unlike ZIP, most operating systems can't open a RAR file without installing extra software, and browsers and web apps have essentially no native support for it at all. ZIP, by contrast, is an open format that almost every device and platform can open natively. This tool reads a RAR archive's file listing and, where possible, repacks its contents into a ZIP that opens anywhere without extra software.
An honest note about RAR compression
RAR's actual data compression algorithm is proprietary and has never been openly published by its creator, which makes a full, general-purpose RAR decompressor impractical to build as a small client-side script. This tool fully and correctly supports the common case of archives stored with RAR's "no compression" (stored) option, copying those files out byte for byte. For files compressed with RAR's proprietary algorithm, it reports them clearly by name rather than guessing or silently failing.
How the conversion works
The tool parses the RAR 4.x archive header structure directly, reading each file entry's name, size, and storage method. Entries stored without compression are copied directly into a new ZIP archive built with the JSZip library. The conversion report tells you exactly how many files were successfully copied and lists any files that used RAR's own compression and couldn't be repacked this way.
When this tool is the right fit
This works well for RAR archives created specifically without compression, sometimes used for archives of already-compressed files like photos or videos where further compression wouldn't help anyway, or for RAR files created purely as a way to bundle files together rather than to shrink them. If your archive was built with RAR's standard compression settings, a dedicated desktop unarchiving tool remains the reliable option for full extraction.
What to do with unsupported entries
If the report shows skipped files, that simply means those particular entries were compressed with RAR's own algorithm. Free tools like 7-Zip (on Windows) or The Unarchiver (on Mac) can open essentially any RAR file, including compressed ones, letting you extract the contents and then use this site's ZIP File Creator to package them into a ZIP if that's your end goal.
Step-by-step walkthrough
Drop your .rar file onto the upload area or click to browse for it, then click Convert to ZIP. The tool parses the archive's header structure and reports exactly how many entries it could copy directly versus how many used RAR's own compression and had to be skipped. If the report shows every entry succeeded, click Download ZIP to save the finished archive; if some were skipped, see the article above for how to handle those with dedicated software.
Privacy and performance
Because the rar to zip converter runs as JavaScript inside your own browser tab rather than on a remote server, there's no upload step, no waiting on a network connection, and no copy of your file sitting on someone else's infrastructure afterward. That also means it keeps working exactly the same whether your file is a few bytes or several megabytes, limited only by your own device's memory rather than a server's queue or rate limit. If you ever want to double-check that nothing is being transmitted, your browser's built-in developer tools network tab will show no outgoing request for the file's contents at any point during conversion. This also means the tool keeps working offline once the page has loaded, and closing the tab afterward leaves no copy behind on any server, since one was never made in the first place. That's a meaningful difference from typical online converters, which usually require uploading your file to a remote service before you ever see a result.
Frequently Asked Questions
Does this tool work with all RAR files?
It fully supports archives stored without compression. Files compressed with RAR's proprietary algorithm are detected and reported, but can't be decompressed by this client-side tool.
Why can't it decompress every RAR file?
RAR's compression algorithm is proprietary and undocumented, which makes a complete implementation impractical for a small browser-based script; this is explained honestly in the conversion report.
What should I do if my files were skipped?
Use a free desktop tool like 7-Zip or The Unarchiver to fully extract the RAR archive, then use this site's ZIP File Creator tool to package the extracted files into a ZIP.
Does it support RAR5 format archives?
This tool targets the RAR 4.x header format; RAR5 archives use a different header structure and aren't currently supported.
Is my RAR file uploaded anywhere during conversion?
No, the archive is parsed and repacked entirely inside your browser tab.
