What Is an Audio Converter?

An audio converter changes the file format of an audio recording — from whatever you have to whatever you need. Different devices, apps, and platforms expect different formats: MP3 for broad compatibility, WAV or FLAC for lossless editing, M4A for Apple devices, Opus for efficient streaming.

Our converter decodes your source file and re-encodes it in the target format, keeping quality as high as that format allows — lossless formats (WAV, FLAC, AIFF) preserve the audio exactly, while compressed formats (MP3, M4A, OGG, Opus) use high-quality settings by default.

Frequently Asked Questions

Is the audio converter really free?
Yes, completely free. No trial period, no credit card, no catch.
Which format should I pick?
MP3 for general use and maximum compatibility. WAV, FLAC, or AIFF if you need lossless quality for editing. M4A for Apple devices. OGG or Opus for smaller files at good quality.
Will converting to a lossy format reduce quality?
Converting from a lossless source to a compressed format (MP3, M4A, OGG, Opus) does involve some quality loss, though our default settings are tuned to keep it imperceptible for most listening. Converting to a lossless format (WAV, FLAC, AIFF) never loses quality.
