Frequently asked questions
Is my M4A file uploaded?
No. The conversion runs in your browser with FFmpeg compiled to WebAssembly. The first use downloads the converter (about 30 MB); your file never leaves your device.
Why convert M4A to WAV?
M4A is the AAC audio format used by iPhones, iTunes and voice memos. WAV is uncompressed, so files are about ten times larger than MP3.
Will WAV sound better than the M4A?
No. The file gets larger but the sound stays the same; detail removed by M4A compression cannot be restored.
