Convert ZIP to 7Z online

Convert ZIP to 7z when you want to repack an archive into a format that can compress many file sets more tightly than standard ZIP.

When should you convert ZIP to 7Z?

  • Recompress folders before long-term storage
  • Bundle downloads into a 7z archive
  • Reduce archive size for large mixed file sets
  • Move files into a format preferred by 7-Zip users

Before you convert

Compatibility tradeoff

7z can compress well, but ZIP opens by default on more operating systems without extra software.

Archive contents stay files

This repacks the archive; it does not convert the documents, images, or media inside it.
