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 CPIO to TAR.GZ 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.
CPIO (Copy In/Out) is a Unix archive format designed for backing up file systems. It preserves file permissions, timestamps, and ownership information. CPIO is used internally by RPM packages and for creating initramfs images in Linux systems.
This tool extracts CPIO archives to access backed-up files and data.

A tar.gz file is basically two files wrapped into one. The first one is a tar file (sometimes referred to as a tarball), a collection of files & folders wrapped into a single package. The tar file then gets compressed into a gz file, utilising the GNU zip (gzip) compression algorithm.
This is a common pattern used in unix/linux environments to bundle multiple files for easier distribution or backup.
Tgz and tar.gz files are essentially the same thing, just with different file extension.

Why client-side CPIO to TAR.GZ conversion is faster and more private
ezyZip converts CPIO to TAR.GZ 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.
