About this tool
WAV is broadly accepted by DAWs, editors, transcription tools, presentation software, and professional audio workflows.
The MP4 picture is removed and its audio becomes uncompressed PCM, so the WAV can be substantially larger than the source.
Processing time depends on duration, source bitrate, output format, and device performance.
Frequently asked questions
Does WAV recover quality lost in the MP4?
No. It preserves the decoded source without another lossy encode, but cannot recreate audio information removed earlier.
Is my MP4 file uploaded?
No. FFmpeg WebAssembly performs the conversion in your browser. The engine downloads from a CDN, but your media stays on your device.
What is the maximum file size?
The browser converter accepts files up to 200 MB. Long files may require substantial device memory.
