MP4 to WAV Conversion FAQ
Is the MP4 to WAV converter free?
+
Yes. One conversion an hour is free, with no account needed, for a file within the free size limit. A paid plan removes the hourly limit and the size limit, and lets you add several files to one job.
Does converting MP4 to WAV improve the audio quality?
+
No, and it is worth being blunt: nothing can. The MP4 already discarded detail during its original encode, and wrapping what remains in a lossless WAV preserves exactly that — no more. The file gets several times larger and sounds identical. It is still the right move before editing, because WAV will not add a second generation of artefacts when you export. WAV is the correct format for editing, mastering and archiving, because it can be re-encoded any number of times without accumulating artefacts. MP4 only supports one widely-honoured subtitle format (mov_text), and multi-track audio is unreliable outside desktop players.
How big an MP4 file can I convert to WAV?
+
Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.
Can I convert many MP4 files to WAV at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
Does the MP4 to WAV converter work on phones and tablets?
+
Yes — the UI is responsive and the conversion pipeline runs server-side, so mobile devices upload-then-download just like desktops. iOS and Android browser file pickers (camera roll, Files app) work end-to-end.
Which browsers does the MP4 to WAV converter support?
+
Chrome, Firefox, Safari (15+), Edge, and Opera. The converter uses standard `<input type="file">` upload — no WebAssembly or PWA dependencies — so even older browsers work.
Are my MP4 files kept private?
+
Yes. Uploaded MP4 files are processed on our own servers and are never viewed or shared. Uploads and results are deleted automatically about 24 hours after conversion. See /privacy/ for the full policy.
What if the WAV download doesn't start automatically?
+
Disable any pop-up blocker, then click the download button manually. The result link stays active for 24 hours, so if your network fails mid-download, you can re-trigger from the result page without re-uploading the MP4.
How long does MP4 to WAV conversion take?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
Do I need to install software to convert MP4 to WAV?
+
No — the converter runs entirely in your browser plus our servers. No desktop install, no plugin, no extension. Just upload, wait, download.
