Convert Video to MP3 Online

Upload any video file or paste a URL to extract the audio as a high-quality MP3. Works with all major video formats.

How it works

  1. Add your video via URL or file upload. Paste a link from YouTube, TikTok, Instagram, or Facebook — or upload a local video in MP4, WebM, MOV, or AVI format directly into DomeScribe.
  2. Confirm MP3 as the output format. MP3 is pre-selected as the target format. DomeScribe defaults to a high 320 kbps bitrate so your converted file sounds crisp on any speaker or headphone.
  3. Convert the video to MP3. Click Convert and DomeScribe will transcode the video audio into a high-quality MP3 file. Most conversions finish within a few seconds regardless of video length.
  4. Download your MP3 file. Hit the Download button to save the MP3 to your device. The file is compatible with every major music player, phone, and car stereo system.

Frequently asked questions

What bitrate does DomeScribe use for MP3 conversion?

DomeScribe defaults to 320 kbps CBR (constant bitrate), which is the highest standard MP3 quality. This ensures your converted files sound virtually indistinguishable from the original audio.

Can I choose a lower MP3 bitrate to save space?

At this time DomeScribe outputs MP3 at a fixed high bitrate for the best listening experience. If you need a smaller file, you can re-encode the downloaded MP3 with any free audio editor.

Which video formats can I convert to MP3?

DomeScribe accepts MP4, WebM, MOV, AVI, MKV, and FLV files for MP3 conversion. You can also paste a URL from YouTube, TikTok, Instagram, or Facebook and the tool will convert the video audio to MP3 automatically.

How long does a video-to-MP3 conversion take?

Most DomeScribe conversions complete in under ten seconds regardless of video duration. Processing time depends mainly on your internet speed for URL-based videos or upload speed for local files.

Will the MP3 file include video metadata like the title?

DomeScribe carries over basic metadata such as the title and duration when available from the source. You can edit ID3 tags afterward in any music library app to add artist, album, or artwork information.
