Frequently Asked Questions
Why convert M4A to WAV?
M4A (MPEG-4 Audio) uses lossy or lossless (AAC/ALAC) encoding and is best for Apple ecosystem — iTunes, iPhones, iPads, and macOS music libraries. WAV (Waveform Audio File Format) uses uncompressed lossless encoding and excels at professional audio editing, mastering, and archival in DAWs and production software. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
ALAC or AAC source — matters?
Hugely: ALAC converts bit-perfectly (lossless to uncompressed); AAC loses a generation (transparent at high bitrates, but lossy). Check the source codec first.
Why WAV for DAWs?
Pro Tools, Logic, and Audition ingest WAV natively with sample-accurate editing. M4A containers complicate timelines — convert once at project start.
How big are WAV outputs?
Roughly 10 MB per stereo minute at 44.1 kHz/16-bit. A 60-minute session needs ~600 MB disk — plan before batching.
Do Apple files leave the browser?
No — conversion runs locally in your browser with FFmpeg. Saves never touch a meter — downloads on local tools are unlimited.
