About the Convert to Audio tool
Convert to Audio pulls the sound out of video files or re-encodes an existing track into the format your player, podcast host or editing suite expects.
Extract the sound from a video, podcast recording, or voice memo and save it as a clean MP3. It works with most common video and audio formats, so you can pull the audio track out of a clip without needing a video editor.
How to convert a file to audio
- 1Upload the video or audio file you want to convert.
- 2Wait while the audio track is extracted and encoded to MP3.
- 3Download the MP3 file to your device or cloud storage.
When to extract audio from a file
Pulling audio out of a video is useful when you only need the soundtrack: a lecture, a music performance, an interview, or a voiceover you want to reuse in a podcast. Converting to MP3 also shrinks the file drastically compared to keeping the full video, which makes it easier to store or share by email.
The tool reads the audio stream from your upload and re-encodes it, so the result plays on virtually any phone, computer, or media player. Files are sent over an encrypted connection and are removed from our servers automatically after processing, and there is no account or sign up required to use the converter.
Output size depends on the length of the source and the bitrate chosen; a typical hour of speech becomes a file of a few tens of megabytes, well within email attachment limits.

Frequently asked questions
Can I extract audio from a video that has no separate audio track listed?+
As long as the video file actually contains sound when you play it, the converter can find and extract that track. If the video is silent, the output MP3 will simply be silent too.
What bitrate does the MP3 come out at?+
The converter uses a standard bitrate that balances sound quality and file size for speech and music alike. This keeps files small enough to share easily while remaining clear on speakers and headphones.
Will the converted audio be perfectly in sync with the original video?+
Yes, the extraction preserves the original timing of the audio track, so if you later pair it back with the video it will still line up correctly.
Does converting to audio remove background music or noise?+
No, the tool extracts the audio exactly as it exists in the source file. If you need noise removal or vocal isolation, that requires separate audio editing software.
Is there a limit on how long the source video or audio can be?+
Very long files may take longer to process and produce larger MP3s, but there is no arbitrary restriction on typical podcast or lecture length recordings.
Is my uploaded file kept after conversion?+
No, files are transferred over an encrypted connection and deleted automatically from our servers after the conversion is complete.
