What are audio formats?

Audio files can be stored in different formats depending on whether the goal is quality, compatibility, or compression. Some formats use lossy encoding to reduce file size, while others preserve more of the original signal for editing and archiving.

The format you choose affects playback support, file size, and how much detail survives re-encoding. Converting audio is useful when a device, app, or workflow expects a specific codec or container.

Tool description

This tool converts an uploaded audio file to another format directly in the browser. Choose the output format, optionally set a bitrate for lossy codecs, and download the converted file once processing finishes.

It is useful for preparing clips for websites, editing tools, messaging apps, or devices that only accept certain audio types.

Examples

Common conversions:

  • Convert WAV recordings to MP3 for smaller sharing files
  • Convert FLAC masters to M4A or OGG for broader playback support
  • Convert an audio memo to WAV when another tool requires an uncompressed input

Features

  • Browser-side conversion: Uses FFmpeg in the browser, so the file stays on your device
  • Multiple output formats: Supports the most common audio formats for sharing and editing
  • Bitrate control: Lets you tune compression for formats where bitrate matters

Supported formats

Input:

  • Any audio file that FFmpeg can decode in the browser

Output:

  • MP3
  • M4A
  • OGG
  • WAV
  • FLAC

Limitations

  • Bitrate settings do not affect WAV or FLAC output.
  • Very large files may take longer to process in the browser.
  • The tool depends on WebAssembly support and enough local memory for conversion.
