Yes. ezyZip utilises the processing power of your own computer and browser to complete the task. No file data leaves your browser. Unsure? Turn off your WiFi when completing the uncompression. It will continue to work as no data is uploaded to the internet.

ezyZip is a free online SFX 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.

An SFX file (Self-Extracting archive) is an executable file that contains compressed data along with built-in extraction code. Unlike standard archive formats, SFX files do not require any decompression software to be installed on the recipient's computer — the user simply runs the file and the contents are automatically extracted.

SFX archives are commonly created from ZIP, RAR, or 7Z archives and are widely used for distributing compressed files to users who may not have archive utilities installed. ezyZip uses the 7-Zip format to generate its SFX archives, producing .exe files that will self-extract on Windows platforms. ezyZip can also safely extract the contents of SFX files directly in your browser without needing to run the executable, avoiding potential security risks.

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 SFX to ZIP conversion is faster and more private

ezyZip converts SFX 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.
