How to convert audio online

  1. 1

    Upload your audio file

    Choose a file from your device or drag it into the converter. Common formats like MP3, WAV, FLAC, M4A, AAC, OGG, and even many video sources are supported.

  2. 2

    Choose the output format

    Pick the format you need, then adjust bitrate if you want a different balance between quality and file size. This is helpful when you need broad compatibility, a smaller file, or a format a device prefers.

  3. 3

    Convert and download

    Start the conversion and download the new audio file when it finishes. The conversion runs in your browser, so you can convert audio online without handing the source file to a remote service.

Understanding the settings

MP3 is the safest everyday choice when you want an audio file that works almost everywhere. M4A with AAC is a strong fit for Apple devices, while WAV and FLAC are better when you want lossless output for editing or archiving. Lower bitrates create smaller files, but they also discard more detail, so for general listening a balanced MP3 setting is usually the right place to start. If the source is already lossy, converting it again will not restore the information that was lost in the original file.

Best settings for common goals

Everyday compatibility

MP3 at 192 kbps.

It is a strong default for music, podcasts, and general sharing because it plays almost everywhere without surprises.

Apple ecosystem

M4A (AAC) at 256 kbps.

AAC is efficient and deeply supported on iPhone, iPad, AirPods, and Apple software.

Practical guidance

How to choose the right audio output

The best destination format depends on what happens after the conversion. Playback compatibility, editing needs, archive goals, and file size all point toward different answers.

  • Use MP3 when you want the safest all-purpose output.
  • Use AAC or M4A for strong mobile efficiency, especially in Apple-focused workflows.
  • Use WAV or FLAC when future editing or archive quality matters more than file size.

Compatibility, privacy, and limitations

Lossy vs lossless

WAV and FLAC preserve the source without lossy re-encoding, but they create much larger files. MP3, AAC, and OGG are better choices when portability and smaller file size matter more than archival fidelity.

Privacy explanation

Audio conversions often involve interviews, meetings, lectures, or personal voice recordings. Local processing lets you change format without pushing those files through a remote converter.

Things to keep in mind

  • Converting from one lossy format to another does not restore detail that was already discarded in the original source.
  • Very large or long recordings still depend on browser memory, especially when converting from video sources.
