ezyZip is a free rmvb sound track extractor that runs in your browser. No need to install any additional converter software. It supports a myriad of other sound extractions too.
Unlike other online media conversion utilities, ezyZip DOES NOT enforce file size restrictions or require uploading files to a server. It runs locally as a browser app, thus making it much quicker than other online conversion tools. This means you'll be able to convert large media files! 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.

Why client-side audio extraction from RMVB video is faster
ezyZip extracts audio from RMVB video files using a WebAssembly-compiled media engine. Here is why local audio extraction is faster:
- Stream Copy When PossibleThe engine demuxes the video container and isolates the audio stream without a full video decode when the audio codec is compatible, completing in a fraction of the time a full transcode requires. For example, extracting AAC audio from an MP4 video can complete in seconds since no re-encoding is needed.
- 200+ Container FormatsOver 200 container formats are supported through the comprehensive compiled codec library. Whether your source is MP4, MKV, AVI, MOV, WebM, or a less common container, the engine can locate and extract the audio track.
- Dedicated Worker ThreadThe entire operation runs in a dedicated Web Worker, keeping your browser responsive during processing. Progress tracking shows demuxing and encoding stages separately so you can see exactly what the engine is doing.
- Multi-Track SelectionFor video files containing multiple audio tracks (different languages, commentary tracks, etc.), the engine lets you select which track to extract rather than blindly pulling the first one. Track metadata like language and codec type are displayed for informed selection.
