Free MP4 to MP3
Convert video to MP3 (free, no upload)
Extract the soundtrack from an MP4, MOV, WebM, or MKV and download an MP3. Trim the clip if you only need part of it. The file never leaves this tab.
Free video compressor — no file size cap, no watermark. Your browser’s memory is the only limit.
How to convert MP4 to MP3 without uploading
Upload converters store your video on a server so they can rip the audio. Shrink Clip’s video to MP3 tool does the same job in the browser: drop the file, pick 128 kbps for speech or 192–320 kbps for music, and download. No account and no watermark on a soundtrack.
Use trim for lectures, calls, or a song inside a longer clip. If you still need a small video for WhatsApp, switch to Compress instead of stripping the picture entirely.
MP4 to MP3 FAQ
- How do I convert MP4 to MP3 for free?
- Open this page, drop the MP4, pick a bitrate (128 kbps for speech, 192 or 320 for music), and download the MP3. Conversion runs in your browser — the video is not uploaded.
- Can I extract audio from MOV or WebM?
- Yes. Shrink Clip accepts MP4, MOV, WebM, AVI, and MKV, then writes an MP3. Trim the timeline if you only need part of the soundtrack.
- Is this an online video to MP3 converter?
- It runs in the browser, but it is not an upload converter. The file stays on your device. That is safer for lectures, calls, and private clips than a site that stores the video.
