Frequently asked questions
How do I convert MP4 to MP3?
Choose your MP4 (or MOV, MKV, WebM) video, keep MP3 selected and press Extract audio. The MP3 downloads when it is ready.
Which bitrate should I choose?
192 kbps is great for music and speech. Use 128 kbps for smaller files (podcasts, lectures) and 320 kbps for the best quality.
Can I get lossless audio?
Choose WAV for uncompressed audio, or M4A to keep AAC audio (often copied directly from the video without any loss).
Is it legal?
Converting your own videos is fine. Respect copyright and only convert content you have the right to use.
