Audio Converter

1. Upload any AAC, AIFF, FLAC, M4A, MP3, OGG, and WAV file.
2. Choose the output format you need.
3. Click Convert.
4. Download the converted file — usually ready in a few seconds.

Every format below converts to every other one — upload any of these, pick any other as your target:

M4A is what an iPhone voice memo, a Mac screen recording, and most Apple Music downloads come out as. It plays fine on Apple devices — and then fails on the one thing that matters: a car head unit, an older MP3 player, a USB stick in a rental car, or Windows software that only reads MP3. Converting to MP3 fixes that.

Upload the .m4a above and choose MP3 — that's all there is to it. It runs in the browser on any device, so there's no iTunes, no Music app, and nothing to install. Both formats are compressed, so this is a compatibility change rather than a quality one: you're changing what can play the file, not improving or degrading the audio. If the M4A is instead headed into a DAW or a sampler, choose WAV so you're not stacking a second lossy generation before you process it.

Those two go both ways and each has a dedicated page with file-size math and the honest quality story: use the WAV to MP3 converter to shrink a big uncompressed file for sharing, or the MP3 to WAV converter to get an uncompressed file for editing. You can also do either right here.

These are just examples — every format above converts to every other one, not only the pairs shown here:

MP3

Sharing, casual listening, small file size

WAV

Editing, sampling, DJ software — lossless

FLAC

Archiving at full quality with a smaller footprint than WAV

M4A

Apple devices and Apple Music/iTunes compatibility

AAC

Mobile and streaming — similar to MP3, often smaller at equal quality

OGG

Open-source software and games

AIFF

Professional editing on Apple/Logic-based workflows — lossless

Want the deeper technical explanation of lossless vs. lossy, and why converting up to WAV doesn't recover lost quality? Read Lossless vs Lossy Audio: Which Format to Use.

Since conversion works on the file format itself rather than where it came from, this handles exports from Audacity, Adobe Audition, Ableton Live, Logic Pro, FL Studio, GarageBand, OBS, Premiere Pro, DaVinci Resolve, or anywhere else — as long as the file is one of the formats above.

Need to trim, reverse, or adjust a file before or after converting it? The Audio Trimmer, Pitch Shifter, and Tempo Changer all work on any of these formats too.
