Frequently asked questions
Is this MP3 converter free?
Yes — it's completely free with no signup, no limits and no watermarks.
Are my files uploaded anywhere?
No. All conversion happens locally in your browser using the Web Audio API, so your audio never leaves your device.
Which formats can I convert from?
Any audio your browser can decode, including WAV, OGG, FLAC, M4A, AAC and more.
What bitrate should I choose?
192 kbps is a great balance of size and quality. Choose 320 kbps for the best quality, or 128 kbps for the smallest files.
Does this use CBR or VBR encoding?
CBR (constant bitrate) by default, so file sizes are predictable and every player seeks accurately. You can switch to VBR under the quality control, which varies the bitrate by passage and usually gives a smaller file at the same quality.
