Which audio format keeps the best quality?

WAV and FLAC are lossless — no quality is lost. MP3 and AAC are compressed and much smaller, with quality loss that's usually inaudible at normal bitrates.

Can I extract audio from a video file?

Yes — upload an MP4, MOV, MKV or other video and choose an audio format as the output; only the soundtrack is converted.

Is there a daily limit on conversions?

No. Convert as many audio files as you need, with no registration and no daily cap.
