AAC is the audio codec behind most streaming and Apple devices. Raw .aac files don’t carry tags and some apps won’t open them. MP3 is the universal compressed audio format. It plays on every phone, car stereo and music app.
Converting to MP3 gives you audio that plays on absolutely everything. The conversion happens entirely in your browser, so your files are never uploaded and there’s no size limit beyond your device’s memory.
How to convert AAC to MP3
- Choose your AAC file.
- Pick the audio quality, and set a start and end time if you only need part of it.
- Press Convert and download the MP3.
