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 wma to 128kbps bitrate converter that runs in your browser. No need to install any additional compression software. It supports a myriad of other media types and bitrates.
Unlike other online media 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.
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. Take a look at the feature comparison below and we think you'll agree that ezyZip is the better choice for your file conversion needs.

Why client-side WMA bitrate conversion is faster
ezyZip's WebAssembly media engine provides precise control over bitrate encoding parameters. Here is why local bitrate conversion is faster:
- Fine-Grained ControlPrecise control over minimum rate, maximum rate, and buffer size — all executing locally in your browser. You can target specific bitrates like 128 kbps, 256 kbps, or 320 kbps for audio, or set custom video bitrates in Mbps for exact output quality.
- Adaptive Quality OptimizationThe quality margin algorithm optimizes output at your target bitrate through rapid local iterations. The encoder analyzes content complexity and adjusts its rate-control strategy to deliver the best possible quality at your specified bitrate.
- Multi-Threaded EncodingSharedArrayBuffer enables multi-threaded processing, accelerating encoding for long audio and video files. On modern multi-core devices, this parallel approach can cut encoding time by 2–4x compared to single-threaded tools.
- Real-Time ProgressProgress feedback comes directly from the local WASM encoding pipeline, showing frame count, elapsed time, and estimated completion. No waiting blindly for a remote server to finish processing in an opaque queue.
