Which quality (kbps) should I choose?
| Use | Recommended kbps | Notes |
|---|---|---|
| Music | 192k – 320k | Higher fidelity; larger files. |
| Podcast / voice | 96k – 128k | Great balance for speech (mono recommended). |
| Share via WhatsApp/email | 64k – 96k | Very small; enough for voice notes. |
If something doesn’t work (common errors)
- Doesn’t play on your device: make sure you export to MP3 (avoid OGG/OPUS/AMR for maximum compatibility).
- Low volume: convert to MP3 and then normalize the volume in an editor (e.g., Audacity).
- Your MP3 is too large: use 64–128 kbps (voice) or go through MP3 → smaller MP3.
- Not sure what format it is: upload it to the converter; it will detect the extension and you can export to MP3 anyway.
