Frequently Asked Questions

Which audio input formats are supported?
Any format your browser can decode, which typically includes MP3, WAV, OGG, FLAC, AAC, M4A, OPUS, and WEBM. Chrome and Firefox support the widest range of formats.
Is there a file size limit?
There is no enforced limit. However, very large files (over 500 MB) may be slow to process since all computation happens in your browser. For best results, process large files individually.
Why does OGG/WebM take longer to convert?
OGG/WebM encoding uses the browser's MediaRecorder API, which processes audio in real-time. This means a 3-minute track takes ~3 minutes to encode. MP3 and WAV are processed instantly using a direct encoding algorithm.
Are my audio files uploaded to a server?
Absolutely not. All processing uses the Web Audio API and runs entirely in your browser. Your files never leave your device, ensuring complete privacy.
What does "Normalize Audio" do?
Normalization automatically adjusts the overall volume so the loudest peak reaches -0.9 dBFS — the maximum safe level without clipping. This makes quiet recordings louder and prevents distortion in loud ones.
Can I convert multiple files at once?
Yes! Upload as many files as you like. All settings apply uniformly to every file in the batch. Files are converted sequentially and each gets its own download button when complete.
