MP4 to MP3 Converter

Extracting audio from video is useful in many scenarios:

• Music & Podcasts: Save audio from music videos, interviews, or podcasts for offline listening without the video component.
• Educational Content: Listen to lectures, tutorials, or audiobooks while commuting - no screen required.
• Save Storage Space: Audio files are much smaller than video. A 100MB video might produce a 10MB MP3 file.
• Share Easily: Send audio clips via email or messaging apps that have file size limits.
• Content Creation: Extract voice recordings from video for use in other projects or formats.

The converter extracts the audio track from your MP4 file and encodes it to the MP3 format:

1. Upload your MP4 video file
2. Select your preferred audio quality (bitrate)
3. The audio track is extracted from the video container
4. Audio is encoded to MP3 format
5. Download your MP3 file

Choose the bitrate that balances quality and file size for your needs:

• Default: Preserves the original audio quality from the source video. Best for maintaining existing quality.
• 96 Kbps: Compact file size, suitable for voice recordings and spoken content.
• 128 Kbps: Good balance of quality and size for general listening. Standard for many streaming services.
• 192 Kbps: Higher quality for music listening with noticeable improvement over 128 Kbps.
• 256 Kbps: Near-CD quality. Excellent for music and detailed audio content.
• 320 Kbps: Maximum MP3 quality. Best when your source video has high-quality audio.

Note: Higher bitrates only improve quality if the source audio supports it. Converting low-quality audio to 320 Kbps won't improve its actual quality.

MP4 (MPEG-4 Part 14) is a digital multimedia container format that can store video, audio, subtitles, and still images. Key characteristics:

• Container Format: MP4 is a container that holds video and audio streams, typically using H.264 for video and AAC for audio.
• Universal Support: Plays on virtually all devices, browsers, and media players.
• Streaming Capable: Designed for both download and streaming playback.

MP3 (MPEG Audio Layer III) is the most widely supported audio format, using lossy compression to reduce file size while maintaining good quality:

• Universal Compatibility: Plays on every audio device, smartphone, computer, and media player.
• Efficient Compression: Reduces file size by 10-12x compared to uncompressed audio while preserving perceptible quality.
• Variable Bitrate: Can use constant or variable bitrate encoding to optimize quality per file size.
