Compressed, smaller files
Lossless, exact quality
Quality
Higher quality means a larger file. WAV and FLAC are lossless and ignore this setting.
Bit depth
This format is lossless: quality is preserved and the quality setting does not apply.
Channels & sample rate
Channels
Mono halves the size of compressed formats and suits voice recordings.
Sample rate
44.1 kHz is the CD standard, 48 kHz the video standard, and 22.05 kHz is enough for speech.
Opus always plays at 48 kHz, so the sample rate cannot be changed.

About Audio Converter

The Audio Converter changes an audio file from one format to another in seconds. Convert to MP3, WAV, OGG, FLAC, M4A, or Opus from a wide range of inputs including AAC, WebM, and MP4 audio, handy when a device, editor, or platform only accepts a specific format.

For lossy targets you pick a quality preset from Compact 128 kbps up to Studio 320 kbps, trading file size against fidelity, with an estimated output size shown up front. WAV and FLAC are lossless: they preserve the audio exactly and simply ignore the quality setting.

Conversion runs on the server, you can preview the result on the page, and the converted file downloads directly. The tool is free and requires no account.

How to use Audio Converter

  1. Upload the source file: most common audio formats are accepted.
  2. Choose the target format: MP3, WAV, OGG, FLAC, M4A, or Opus.
  3. For lossy formats, pick a quality preset from 128 to 320 kbps.
  4. Click Convert, preview the result, and download the converted file.

Frequently asked questions

Output formats are MP3, WAV, OGG, FLAC, M4A, and Opus. Inputs cover those plus AAC, WebM, and MP4 audio among others, so almost any audio file you have can be converted to the format you need.

Standard 192 kbps is transparent for most listening; choose High 256 or Studio 320 kbps for music you care about, and Compact 128 kbps for voice or when file size matters most. WAV and FLAC ignore the setting entirely.

Lossless formats (WAV, FLAC) keep every bit of the audio at the cost of larger files. Lossy formats (MP3, OGG, M4A, Opus) discard inaudible detail to shrink the file, with the bitrate controlling how much is kept.

No. Converting to a lossless format preserves the audio exactly as it is: it cannot restore detail the original encoding already discarded. It only prevents further loss in subsequent edits.

Yes, converting is free with no signup. Files are processed on the server and cleaned up automatically after conversion.
