Convert M4A to WAV online
Turn M4A recordings into WAV files that are ready for your video timeline or audio editor. Everything is processed in your browser, so interviews and voice notes stay private.
Your files stay on your device: they are processed in this browser tab’s memory and never uploaded.
Ready for editing
Some editors and transcription tools handle M4A poorly or not at all. WAV imports cleanly almost everywhere and stays frame-accurate on a timeline.
Matching your project
Video projects usually run at 48 kHz, so set that here to avoid resampling later. Mono is enough for most single-microphone speech.
FAQ
Is the conversion lossless?
Nothing further is lost when writing the WAV, but compression already applied to the M4A stays in the audio.
Why is the WAV so much bigger?
WAV stores uncompressed samples, while M4A uses compression.
Is my file uploaded?
No. It never leaves your device.
What can you do with an audio converter?
Editors turn phone recordings into WAV files that every timeline accepts; podcasters export a small MP3 from a large master; musicians archive takes as lossless FLAC; and anyone stuck with a file a device refuses to play can switch it to a format that works everywhere.
