Just think of it as a directory that may contain files and more sub-directories once it is opened by a zip utility program. It compresses the data using a lossless algorithm meaning there is no file quality degradation like in some compression formats (e.g. mp3, jpeg). The compression algorithm can vary however the most common is DEFLATE. The standard is constantly evolving with new algorithm and encryption options are added at regular intervals.

Why client-side ZIP creation is faster than server-based tools
ezyZip creates ZIP files using a WebAssembly-powered engine running directly in your browser. Here is why local processing beats cloud-based archivers:
- Direct Disk StreamingCompressed output streams to your disk through the File System Access API using FileSystemWritableFileStream, bypassing memory buffering entirely. This write-through architecture means your available RAM does not limit the archive size you can create.
- Parallel CompressionWeb Workers handle compression in parallel threads, keeping the browser responsive even with large file sets. You can monitor real-time progress for each file while the engine works through your selection.
- No Upload/Download LatencyServer-based tools must receive your upload, compress in a shared queue, and send the result back — local processing skips all three stages. The speed difference is most dramatic for large file collections where upload alone could take longer than the entire local operation.
- Configurable CompressionAdjust compression level, method, and archive settings before creation. The engine supports multiple compression algorithms per format, letting you choose between faster creation or smaller file sizes depending on your priority.
