Frequently asked questions
Is this M4A to WAV converter free?
Yes — completely free, no account, no watermark. The only limit is your device's memory, since everything runs locally.
Are my files uploaded to a server?
No. Your M4A file is processed entirely in your browser using WebAssembly. It never leaves your device.
Will the quality change?
WAV is lossless, so no quality is lost in the conversion.
Can I convert large files?
Yes, but very large media uses a lot of memory. For big files, a desktop browser works best.
