About MakeMyZip

MakeMyZip is a collection of free archive utilities that work entirely inside your browser. You can create, extract, inspect, convert, merge, split, and password-protect archives in ZIP, 7z, TAR, TAR.GZ, and RAR formats — without uploading a single byte to a server.

How it works

Every operation runs client-side using WebAssembly. ZIP operations use JSZip, a JavaScript ZIP library. 7z, RAR, TAR, and GZ operations use 7z-wasm, a WebAssembly port of the 7-Zip engine. Your files are processed in your browser's memory and never leave your machine.

Why we built this

Most online archive tools ask you to upload your files to their servers. That means your tax documents, source code, passwords, and personal photos pass through someone else's infrastructure. Some of those services keep copies. Some don't tell you either way.

We wanted an alternative where you get the convenience of a web tool without giving up control of your data. MakeMyZip is that alternative.

What you can do

  • Create ZIP, 7z, TAR, and TAR.GZ archives with configurable compression levels
  • Extract archives in any supported format — individually or in bulk
  • Inspect archive contents, metadata, compression ratios, and encryption status without extracting
  • Convert between archive formats (e.g., ZIP to 7z, TAR to ZIP)
  • Merge multiple archives into one, with conflict resolution
  • Split large archives into smaller, independently-openable parts
  • Encrypt archives with AES-256 passwords
  • Unlock password-protected ZIP files

Limitations

Because everything runs in your browser, there are some constraints. Very large archives (over 2 GB) may be slow or run into browser memory limits depending on your device. WebAssembly operations are single-threaded, so CPU-intensive compression (like 7z Ultra) takes longer than a native desktop app. RAR archives can be read but not created — RAR is a proprietary format without a public compression specification.
