Audio Converter — Convert Between All Major Audio Formats

Different devices, platforms, and applications require different audio formats. Whether you need to convert a FLAC recording to MP3 for portable use, convert a WAV file to AAC for Apple devices, or prepare audio for a specific platform, our Audio Converter handles all major formats quickly and accurately.

Supported Audio Formats

Lossy formats (smaller file size, some quality loss):

MP3 (MPEG-1 Audio Layer III) — Universal format, widest compatibility
AAC (Advanced Audio Coding) — Better quality than MP3 at same bitrate, used by Apple
OGG Vorbis — Open-source format, excellent quality, used in games and web
OPUS — Modern codec optimized for voice and streaming
WMA (Windows Media Audio) — Microsoft's audio format

Lossless formats (larger file size, perfect quality):

FLAC (Free Lossless Audio Codec) — Open-source lossless, audiophile choice
WAV (Waveform Audio File Format) — Uncompressed, used in professional audio
AIFF (Audio Interchange File Format) — Apple's uncompressed format
ALAC (Apple Lossless) — Apple's lossless codec, compatible with iTunes

Audio Quality Settings

For lossy output formats:

Bitrate: Choose from 64, 96, 128, 192, 256, or 320 kbps. Higher bitrate = better quality and larger file.
Sample rate: 22050, 44100, or 48000 Hz.
Channels: Stereo (2 channels) or Mono (1 channel).

When to Use Each Format

MP3: General use, maximum compatibility with all players and devices. AAC: Apple ecosystem (iPhone, iPad, Mac, iTunes); streaming services. FLAC: Music archiving, audiophile listening, high-fidelity audio systems. WAV: Professional audio production, recording, and editing. OGG: Web audio, game audio, open-source applications. OPUS: Voice calls, low-bitrate streaming, podcast delivery.

Batch Conversion

Convert multiple audio files to the same format simultaneously. Upload several files and apply consistent quality settings to all of them in one operation.

❓ Frequently Asked Questions

For listening, MP3 at 320kbps or AAC at 256kbps provides excellent quality for most ears. For archiving, FLAC preserves the original quality losslessly. For Apple devices, AAC or ALAC are optimized choices.

Yes. Converting from lossless FLAC to lossy MP3 permanently discards some audio data. The reverse (MP3 to FLAC) does not improve quality — it just wraps the same lossy data in a lossless container.

128kbps for casual listening (smaller files), 192kbps for good quality, 320kbps for highest MP3 quality. For audiobooks and speech, 64-96kbps is sufficient.

Some video files with audio tracks can be processed to extract the audio. For dedicated video-to-audio extraction, use our dedicated Extract Audio from Video tool.

Files up to 100 MB can be converted. For very large audio files (long recordings), consider splitting them first.

Both are lossless and maintain perfect quality. WAV is uncompressed (larger files); FLAC uses lossless compression (typically 50-60% smaller than WAV while maintaining identical audio quality).
