ZIP Compressor

Utility: Create ZIP archives from multiple files directly in your browser. Supports Deflate and Bzip2 compression with adjustable levels, plus optional AES-256 password encryption.

Definitions:
- Deflate: The most widely used ZIP compression algorithm, offering a good balance of speed and size.
- Bzip2: A block-sorting compression algorithm that often achieves better ratios than Deflate for text-heavy content.
- AES-256: Advanced Encryption Standard with 256-bit keys — military-grade encryption for your files.

Technical Background: This tool uses a Rust-compiled WebAssembly module running in a Web Worker, ensuring the main UI thread stays responsive even when compressing large files.

Fun Fact: The ZIP format was created by Phil Katz in 1989. The name 'ZIP' implies speed — Katz wanted it to be faster than the competing ARC format!
