WMA (.wma) · Max 20 MB
Podcast hosting platforms like Apple Podcasts, Spotify, and Google Podcasts all support M4A. It's the safe choice for distribution.
For spoken word, 128kbps mono is plenty. Music-heavy podcasts benefit from 192kbps stereo. AudioUtils lets you choose the right balance of size and quality.
Record in the highest quality your setup allows. Convert to your distribution format once, at the end. Every extra conversion degrades lossy audio slightly.
Frequently Asked Questions
Why not just convert WMA to MP3?
MP3 is more universally supported but produces larger files than M4A at the same quality. If you're moving to an Apple device or library (iPhone, iTunes, Apple Music), M4A is the native format and integrates better. If hardware compatibility (older car stereos, cheap MP3 players) matters more, MP3 is the safer pick.
What M4A bitrate should I use?
192 kbps (VBR or CBR) is the sweet spot for music — small files, transparent quality versus most WMAs. 256 kbps if your WMA is high-bitrate (192 kbps+) and quality matters. 128 kbps is fine for voice, audiobooks, and casual listening.
Will my WMA tags transfer?
Basic tags (title, artist, album, year, genre) transfer. WMA's extended tags (writer, content provider, station, etc.) may not map cleanly. For curated libraries, verify with Mp3tag or MusicBrainz Picard after batch conversion.
Does WMA Lossless convert any differently?
If your file is WMA Lossless (rare, but possible from old Windows Media Player rips), the conversion to M4A goes through PCM, then to AAC. You lose the lossless quality in the AAC encode, but you gain compatibility. Convert WMA Lossless to ALAC (Apple Lossless) or FLAC instead if quality matters most.
Will the M4A play on Windows too?
Yes. Windows Media Player on Windows 10/11 plays M4A natively, as do VLC, Foobar2000, MusicBee, and most Windows audio apps. M4A is a superset of compatibility versus WMA — you don't lose Windows playback by switching.
What about DRM-protected WMA?
Old WMA files purchased from MSN Music or similar services may have DRM. Browser-based converters cannot remove DRM — that requires playback through an authorised app on a registered device. If conversion fails on a specific WMA, DRM is the most likely cause.
