About MP4 and WAV
MP4 with H.264 video is the safest format for browsers and phones.
WAV stores uncompressed PCM audio — large files, no quality loss.
MP4 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 MP4 file to WAV?
Add your MP4 file to the box above. convertexa detects the format from the file content, applies the MP4 to WAV conversion and gives you the result to download. The whole operation runs inside your browser.
Are my MP4 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 MP4 to WAV conversion lossless?
Yes. This conversion preserves all of the source data, so the WAV file is equivalent to the original MP4 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.
