Audio Conversion Tips
Get the best results from your conversions.
Pick the Right Format
Use MP3 or M4A for everyday sharing, WAV or FLAC when you need lossless quality for editing or archiving.
Bitrate vs. Size
Higher MP3 bitrates sound better but produce larger files. 192 kbps is a great balance for most music.
Extract Audio from Video
Drop an MP4, MOV, or WebM file and the converter pulls out just the audio track for you.
100% Private
Everything runs in your browser with WebAssembly. Your files are never uploaded to a server.
Frequently Asked Questions
Which audio formats can I convert between?
You can convert to MP3, WAV, OGG, M4A (AAC), and FLAC. As input you can use any of those formats plus WebM audio — and you can even drop in a video file and we'll extract just the audio track.
Can I convert multiple files at once?
Yes. Add as many files as you like to the queue and click Convert All. Each file is processed one after another, and if one file fails the rest keep going.
What do the MP3 bitrate options mean?
Bitrate controls the trade-off between file size and quality. 128 kbps is compact, 192 kbps is a good all-round default, and 320 kbps is the highest MP3 quality with the largest file size.
Is my audio uploaded to a server?
No. All conversion happens locally in your browser using WebAssembly. Your files never leave your device, so the process is completely private.
How do I download everything at once?
After conversion you can download each file individually, or click Download All to bundle every converted file into a single ZIP archive.
