Popular Audio Conversions

The most common audio conversions our users perform:

FLAC to MP3

Convert lossless FLAC files to MP3 for compatibility with all devices and music players. Reduce file sizes significantly while maintaining good audio quality.

M4A to MP3

Convert iTunes and iPhone audio files to universal MP3 format. M4A files from Apple don't always play on non-Apple devices - MP3 works everywhere.

WAV to MP3

Compress large uncompressed WAV files to MP3. Perfect for sharing music or creating smaller files for portable devices.

MP3 to WAV

Convert MP3 to uncompressed WAV for audio editing or CD burning. Some software requires WAV format for proper processing.

OGG to MP3

Convert OGG Vorbis files to widely-compatible MP3 format for broader device and software support.

Why Convert Audio Formats?

Common reasons to convert your audio files:

  • Compatibility - Play audio on any device or music player
  • File size - Reduce large lossless files for portable devices
  • Quality - Convert to FLAC or WAV for lossless archiving
  • iTunes/Apple - Convert M4A to MP3 for non-Apple devices
  • Editing - Many audio editors prefer WAV or AIFF format
  • Streaming - Convert to OGG or OPUS for web applications

Audio Format Comparison

Choose the right format for your needs:

  • Best universal format: MP3 - works on every device and player
  • Best quality (lossless): FLAC or WAV - no compression artifacts
  • Best for Apple: M4A/AAC - native iTunes/iPhone format
  • Best file size: OGG or OPUS - excellent compression
  • Best for editing: WAV or AIFF - uncompressed for processing

Pro Tip

Keep your original FLAC or WAV files as masters. When you need MP3 for portable devices, convert from these lossless sources for the best quality.

Common Mistake

Converting MP3 to FLAC doesn't improve quality - the detail lost during MP3 compression can't be recovered. FLAC just makes the file larger without adding quality.

Best For

Use our audio converter when you need music for portable devices (to MP3), archiving (to FLAC), or editing (to WAV).

Not Recommended

Avoid converting between lossy formats (like MP3 to AAC) repeatedly - each conversion compounds quality loss. Convert from the original source when possible.
