Choosing the right audio format
MP3 for compatibility
The most widely supported audio format. Works on virtually every device, player, and platform.
WAV for lossless editing
Uncompressed PCM audio at full quality. Best for audio editing, mixing, and production workflows.
FLAC for audiophile quality
Lossless compression reduces file size by 40-60% vs WAV while preserving every audio detail. Perfect for archiving.
OGG & AAC for streaming
OGG Vorbis (open-source) and AAC (Apple ecosystem) both offer excellent quality-to-size ratios for web and mobile streaming.
How to convert audio formats online
Need to convert an audio file to a different format? Whether you're converting FLAC to MP3 for portability, WAV to OGG for a web project, or MP3 to WAV for editing, our free audio converter handles it all.
Upload any audio file — MP3, WAV, OGG, AAC, or FLAC up to 500 MB — choose your target format, and click convert. The tool uses high-quality encoding settings: LAME VBR for MP3, Vorbis VBR for OGG, 192 kbps CBR for AAC, uncompressed PCM for WAV, and lossless FLAC for archival.
Everything runs locally in your browser using FFmpeg WebAssembly. Your audio files are never uploaded to any server. The first use requires a one-time download of the audio engine (~30 MB), after which subsequent conversions start immediately.
Frequently asked questions
What formats can I convert between?
You can convert any combination of MP3, WAV, OGG, AAC (.aac, .m4a), and FLAC. Upload any of these formats and choose any other as the output.
Is the conversion lossy?
Converting to MP3, OGG, or AAC involves lossy compression — some quality is lost. Converting to WAV or FLAC is lossless, preserving full audio quality. The tool uses high-quality encoding settings to minimize any quality loss.
How long does conversion take?
Most audio files convert in seconds. The first conversion requires downloading the audio engine (~30 MB one-time download). Large files (100+ MB) may take up to a minute.
Can I convert FLAC to MP3?
Yes. FLAC to MP3 is one of the most common conversions. The tool uses LAME VBR at ~190 kbps, which provides excellent quality for most listeners while significantly reducing file size.
Are my files uploaded to a server?
No. All processing runs locally inside your browser using FFmpeg WebAssembly. Your audio files never leave your device and are never sent to any server.
