About MP4 to MP3
Sometimes you only want the audio from a video, like a song, a podcast clip, or a lecture, without carrying around the whole MP4. Pulling out an MP3 gives you a small file you can play anywhere and store easily. This tool extracts the audio track from your MP4 and saves it as MP3.
Upload your .mp4 file and the converter separates the sound and encodes it as a standard MP3 that works on any phone, player, or car stereo. It runs in your browser, is free, and never adds a watermark or asks you to register. Your video is processed only to extract the audio and isn't stored, keeping your content private.

FAQ
Does extracting audio change the video file?
No. The tool creates a new MP3 from the audio while leaving your original MP4 untouched.
Will the MP3 sound as good as the video's audio?
MP3 is a compressed format, so it stays close to the source but isn't lossless. For most listening it sounds great.
What if my MP4 has no sound?
If the video has no audio track, there is nothing to extract and the MP3 would be empty or fail.
Can I use MP4 to MP3 on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
