Turn a 7-Zip archive into a RAR archive without installing WinRAR. We extract the contents of your .7z and repack them into a .rar — the files inside are copied byte-for-byte, so nothing is re-encoded or degraded; only the container format changes. Useful when a recipient, upload form, or older tool specifically expects a .rar.
How to Convert 7Z to RAR
- Upload Your 7Z File: Drag and drop your archive onto the page or click "+ Add Files." You can queue several
.7zfiles at once. - Choose Single or Individual Archives: Under "Combine?", pick "Single Archive" to pack everything into one
.rar, or "Individual Archives" to get a separate.rarfor each uploaded file. - Keep the Defaults: RAR is already selected as the output. The defaults are tuned for a clean, broadly compatible archive, so there is nothing else to set.
- Convert and Download: Click "Convert" and download your
.rar. No sign-up, no watermark.
7Z vs RAR: What Actually Changes
The contents are identical after conversion — this is a lossless container swap, not a re-compression that touches your data. What changes is the archive wrapper, its compression algorithm, and which tools open it natively.
| Property | 7Z (7-Zip) | RAR |
|---|---|---|
| Type | Open, free format | Proprietary (win.rar GmbH) |
| Compression | LZMA / LZMA2, typically the highest ratio | RAR algorithm, strong but usually slightly behind 7z |
| Creating archives | Free 7-Zip and many open tools | Historically WinRAR / RAR only; the compressor is closed-source |
| Opening archives | 7-Zip, PeaZip, p7zip; Windows 11 (Oct 2023+) | WinRAR, 7-Zip, PeaZip; Windows 11 (Oct 2023+) extracts |
| Recovery record | No | Optional (helps repair damaged archives) |
| Cost to author | Free | WinRAR is paid (trial/shareware) |
If you do not specifically need a .rar, keeping your 7z (or repacking to ZIP for maximum compatibility) avoids the proprietary format entirely — 7z is free, well-supported, and usually compresses tighter.
Frequently Asked Questions
Does converting 7Z to RAR reduce file quality?
No. The archive is a lossless container, so your files come out bit-for-bit identical to what was inside the 7z. Converting only changes the wrapper and its compression method — it never re-encodes images, video, or documents stored in the archive.
Will the RAR be smaller than the original 7Z?
Usually not. 7z's LZMA2 algorithm typically produces the highest compression ratio of the common formats, so a RAR repack of the same contents is often the same size or slightly larger. Convert to RAR because you need the .rar format, not to save space.
Do I need WinRAR installed to use this?
No. Creating RAR archives has historically required WinRAR or the proprietary RAR tool, but the work happens on our servers — you just upload the 7z and download the finished .rar. Nothing is installed on your device.
Should I convert to RAR or just stay on 7Z?
If a specific person, website, or program demands a .rar, convert. Otherwise 7z is free, open, widely supported, and usually compresses better, so there is little reason to move to a proprietary format. For maximum cross-platform compatibility instead, ZIP is the safest choice.
Can I convert several 7Z files in one go?
Yes. Add multiple .7z files, then choose "Individual Archives" to get one .rar per file, or "Single Archive" to merge everything into a single combined .rar.
Is my file kept private?
Yes. Your upload travels over an encrypted connection, is processed on our servers, and is deleted automatically after a few hours. There is no sign-up, no watermark, and files are never shared or made public. If you only need to pull files out rather than re-pack them, use Extract 7Z instead.
