QUICK ANSWER
Is it possible to convert ZI to RAR?
Yes - ZI converts to RAR.

A .zi file is almost always a ZIP archive with a renamed extension. Extract its contents using any tool, then recompress with WinRAR, which is the only software that can create .rar files. The process takes two steps: extract, then repack.

Why convert ZI to RAR?

A .zi file is a ZIP archive with a non-standard extension. .rar offers slightly better compression ratios on many file types than ZIP, supports AES-256 encryption, and can include recovery records that allow a damaged archive to be repaired - features that ZIP does not offer.

How to convert ZI to RAR

WinRAR APP

Open the .zi file in WinRAR (which detects the ZIP header regardless of extension), extract the contents, then select the extracted files and click Add to create a new .rar archive.

7-Zip FREE

Use 7-Zip to open and extract the .zi file contents (7-Zip reads the ZIP signature directly); then hand the extracted files to WinRAR to create the .rar archive.

Quality & what to watch

  • Only WinRAR can create .rar archives; 7-Zip and PeaZip can read existing RAR files but cannot write them.
  • No data is lost converting from ZIP to RAR - both are lossless containers; extracted files are bit-for-bit identical to the originals.
  • If the .zi is password-protected, you need the original password to extract before repacking as .rar.

Frequently asked questions

Can 7-Zip create the .rar file instead of WinRAR?
No - 7-Zip can extract existing .rar archives but cannot create them; WinRAR is the only widely available tool that writes .rar format.
Do I need to rename .zi to .zip before extracting?
Not with 7-Zip or WinRAR - both detect the ZIP format from the file header regardless of extension; a rename is only needed for tools that rely solely on the extension.
Is RAR worth using instead of ZIP for most files?
RAR offers modest compression and encryption advantages, but ZIP is more universally supported and requires no special software to extract on Windows or macOS.
