MP4 Converters

Most MP4 files contain AAC audio at 128–256 kbps—the standard for streaming services, social media, and phone recordings. Professional content may use higher bitrates (320 kbps) or occasionally MP3 audio embedded in the MP4 container.

When you extract to MP3, we re-encode the audio at 320 kbps (maximum quality) for optimal results. For WAV extraction, you get uncompressed audio perfect for editing or archival.

Many videos exist only as MP4 files—screen recordings, downloaded content, personal videos, conference calls, and lectures. The audio-only version simply doesn't exist separately.

Extracting audio also makes files 10-50× smaller. A 1GB video lecture becomes a 20-50MB MP3, perfect for commutes or podcast apps.

For typical MP4 files (128-256 kbps AAC audio), converting to 320 kbps MP3 produces virtually identical perceived quality. Both are lossy formats, and modern encoders are excellent.

If you need perfect preservation, extract to WAV format instead. WAV is uncompressed, so you get exactly what was in the video file—though the files will be much larger.

A 1-hour MP4 video (typically 500MB-2GB) extracts to MP3 in 10-30 seconds depending on the original bitrate and our server load. WAV extraction is slightly faster since there's no re-encoding.

The bottleneck is usually upload speed, not processing. Once your file reaches our servers, extraction is near-instantaneous compared to the video's runtime.
