Convert MP4 to MP3 - Extract Audio from Videos Instantly

This free MP4 to MP3 converter lets you extract high-quality audio from MP4 videos in seconds. Upload one or more video files, and convert them into clean MP3 files that are perfect for music, podcasts, ringtones, or offline listening. You can convert one file into one MP3 or upload multiple MP4s and receive a ZIP file with separate audio files - no watermark, no login, and 100% free.

Why Convert MP4 to MP3?

MP4 files contain both video and audio, but often you only need the sound. Converting MP4 to MP3 lets you isolate the audio track for reuse, download, editing, or listening on any device. This reduces file size and allows playback on dedicated audio players, phones, smartwatches, and apps that don't support video.

Common Use Cases for MP4 to MP3 Conversion

  • Extract music from music videos
  • Save audio from podcasts recorded as video interviews
  • Convert webinars or lectures for listening while commuting
  • Create soundtracks or background music for editing projects
  • Generate ringtones or alarm tones from clips
  • Capture dialogue from film or voice memos

One File = One MP3, Many Files = ZIP of MP3s

If you upload one MP4 file, you'll get one MP3 file in return. If you upload multiple MP4s, each will be converted individually, and all MP3s will be zipped together into one download. This is perfect for content creators, students, or music enthusiasts processing multiple files at once.

File Naming and Prefix Logic

You can enter a file name prefix to organize your output MP3s. For example, if your prefix is "podcast_ep", your results will be named podcast_ep_1.mp3, podcast_ep_2.mp3, and so on. This helps when organizing season folders, creating playlists, or sharing groups of files with clients or collaborators.

What Is an MP4 File?

MP4 (MPEG-4 Part 14) is a multimedia container that stores video, audio, subtitles, and metadata in one file. It's the most commonly used format for digital video - including YouTube uploads, smartphone recordings, screen captures, and promotional media.

What Is an MP3 File?

MP3 (MPEG-1 Audio Layer III) is a compressed digital audio format. It removes unused data from recordings while maintaining sound quality. MP3s are lightweight, fast to stream, easy to store, and compatible with virtually every device. They're ideal for music, voice recordings, audiobooks, or sound effects.

Why MP3 is the Ideal Output Format

  • Small file size for fast sharing and low storage use
  • Supported by every phone, speaker, and media app
  • No visual data to drain battery or consume bandwidth
  • Easy to clip, trim, remix, or tag in any audio editor
  • Perfect for offline listening or archival

File Size, Compression, and Quality

We use high-bitrate MP3 encoding (default: 128kbps or higher) to retain clarity while ensuring files are manageable. Most conversions will reduce the file size significantly while preserving speech or music quality. Ideal for long recordings or when internet bandwidth is limited.

Security and Privacy

All uploads are encrypted via HTTPS. Files are auto-deleted from our server shortly after conversion. We never view, store, analyze, or watermark your files. Our platform is ad-supported and committed to privacy-first utility.
