Why client-side 7Z to TAR.LZ conversion is faster and more private
ezyZip converts 7Z to TAR.LZ entirely within your browser's WebAssembly runtime. Here is why local conversion outperforms server-based converters:
- Optimal Engine RoutingThe system automatically selects the best decompression and compression engine for each format combination. For large archives, streaming conversion stages data through the Origin Private File System to avoid memory exhaustion while maintaining throughput.
- No Double TransferServer-based converters require uploading the source archive and downloading the converted result — local processing eliminates this double-transfer overhead. For a 1 GB archive on a typical connection, this saves 30+ minutes of transfer time alone.
- Single-Pass TranscodingDecompression and re-encoding happen in a single pipeline within WASM, avoiding intermediate temporary files. The input format is decoded and the output format is encoded in one continuous pass, minimizing disk writes and processing time.
