Upload an AAC file and convert it to MP3 in your browser.
Convert an AAC file when a device, audio player, editor, or other application requires MP3.
The AAC audio is decoded and encoded again as a 320 kbps MP3. Both AAC and MP3 use lossy compression, so a small additional change in quality is possible. Converting is useful for compatibility, not for improving the original audio.
MP3 is widely supported by older car stereos, portable audio players, browsers, editing software, and embedded devices. It can be a useful choice when the recipient or playback device cannot open a raw .aac file.
The output is encoded as a 320 kbps constant-bitrate MP3. This setting is fixed and does not depend on the bitrate of the source AAC file.
A higher output bitrate cannot restore audio detail that was already removed from the AAC.
A small quality change is possible. The AAC file must be decoded and encoded again, and both AAC and MP3 use lossy compression.
The 320 kbps output limits further compression, but the result is not a bit-for-bit copy of the AAC audio.
Yes. The MP3 keeps the sample rate and number of channels of the source AAC file.
Not necessarily. AAC can provide better compression efficiency than MP3, while MP3 may work with a wider range of older devices and applications.
Choose MP3 when compatibility matters more than keeping the original format.
Yes, but converting it again would apply another lossy encoding step and could cause further quality loss. Keep the original AAC file if you may need it later.
No. Your AAC file is processed in your browser and is not uploaded to a server. Very large files may still be limited by the memory available on your device.
