The .7z Format and p7zip: A Universal Solution for Compressing and Securing Your Archives



1. Powerful Compression for All Your Needs

The .7z format has become a benchmark for reducing file size while preserving quality. Whether for storing backups in the cloud, archiving documents, or optimizing server space, this format offers unmatched performance. For example, a 10 GB folder can be compressed to 5–7 GB with no data loss.

Unlike traditional solutions like ZIP, .7z uses intelligent algorithms (LZMA2) that analyze data to eliminate redundancies. This technology is particularly useful for photos, videos, and databases, where space savings can reach 50%.

2. Security: Protect Your Files on Any Device

The strength of .7z lies in its AES-256 encryption, the same standard used by financial institutions to protect transactions. Whether you work on Windows, macOS, or Linux, your files remain secured with a customizable password.

This security is ideal for archiving sensitive documents or storing confidential data, even when stored in the cloud or on shared servers. However, for sharing large or confidential files, it is recommended to use secure links (via cloud platforms or file transfer solutions) rather than sending archives directly as attachments.

3. Cross-Platform Compatibility: One Solution for All Your Teams

The real advantage of .7z is its ability to work on all operating systems:

  • Windows: With 7-Zip, the simple and intuitive official tool.
  • macOS: Via Keka, a free application that integrates seamlessly with the Apple environment.
  • Linux: Using p7zip from the command line or graphical interfaces like PeaZip.

This universality is ideal for hybrid teams. For example, a team member on Linux can archive files in .7z, which can then be opened without issue by a colleague on Windows or macOS. Even Android and iOS smartphone users can access these files through dedicated apps like RAR or iZip.

4. How to Use It Daily

No need to be an expert to take advantage of .7z:

  1. Download the appropriate tool: 7-Zip (Windows), Keka (macOS) or PeaZip (Linux).
  2. Right-click your files and choose “Add to archive.”
  3. Select .7z and add a password if needed.

For collaboration or sharing, prefer creating a secure link to the archive stored on a cloud platform, rather than sending it directly as an attachment. This ensures confidentiality and access traceability.

5. Alternatives Worth Knowing

While .7z is excellent, other formats are worth considering:

  • ZIP: Universal but less performant.
  • TAR.GZ: Popular on Linux for system backups.
  • RAR: Good compression, but paid for creating archives.

Blue Fox’s Take
