How In-Browser TAR.GZ Compression Works

File2File executes local compression algorithms in browser memory using WebAssembly and HTML5 APIs:

  • Applies RFC 1952 standard compression with 32K sliding dictionary.

Zero-Knowledge Privacy Guarantee

Unlike traditional online compression websites that upload your confidential files to remote cloud servers, File2File runs 100% client-side.

Zero-Network-Transmission Privacy Guarantee: 0 bytes uploaded to external servers. All processing occurred locally in your browser sandbox.

Your browser downloads our compiled WebAssembly binary once, and all byte operations run directly within your local hardware RAM. No tracking, no logs, no copies saved.
