About M4V and WAV
M4V is an MP4 container with a restricted MPEG-4 Part 2 stream.
WAV stores uncompressed PCM audio — large files, no quality loss.
M4V files are read by the convertexa engine that ships with this page, so the conversion is identical whether you use this tool or the general converter. The output is produced with the same codec settings for every visitor, which means the same input always produces the same result.
Limitations
- Only the first audio stream is used.
Frequently asked questions
How do I convert a M4V file to WAV?
Add your M4V file to the box above. convertexa detects the format from the file content, applies the M4V to WAV conversion and gives you the result to download. The whole operation runs inside your browser.
Are my M4V files uploaded anywhere?
No. The conversion runs in a sandboxed worker on your own device. Your file never leaves the browser, and nothing is stored on a server.
Is the M4V to WAV conversion lossless?
Yes. This conversion preserves all of the source data, so the WAV file is equivalent to the original M4V file.
Is there a size limit?
For reliable results keep the input under 300 MB. Very large files run out of memory in the browser rather than failing quietly.
Which browsers are supported?
Any current version of Chrome, Edge, Firefox or Safari on a desktop. The conversion engines need WebAssembly and Web Workers, both of which are standard since 2018.
