ezyZip is a free online MDS to ZIP converter that runs in your browser. No need to install any additional converter software. It supports a myriad of other file conversion options too.
Unlike other online archive conversion utilities, ezyZip does not require uploading files to a server. Use it as many times as you want, completely free. It runs locally as a browser app, thus making it much quicker than other online conversion tools. This also ensures your privacy will be protected as no file data will leave your browser.
This tool extracts the files stored inside an MDS/MDF disc image. When you open an MDS image, make sure to select both the .mds and .mdf files together — both are required for extraction to work.
ezyZip processes files directly in your browser. Unlike most online tools, your files are not uploaded to our servers, which means faster processing and better privacy.

Why client-side MDS to ZIP conversion is faster and more private
ezyZip converts MDS to ZIP 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.
