About MP34 Audio & Video Toolkit
MP34 is a small toolkit for everyday audio jobs. Upload a video and pull out its soundtrack as an MP3, or upload an audio file and cut out exactly the fragment you need, for example a ringtone, a quote from a podcast or a piece of a lecture.
Files are processed on the server with FFmpeg and deleted automatically after you download the result or leave the page. There are no permanent uploads and nothing is shared with anyone.
Features

Frequently asked questions
What is the maximum file size?
The limit is shown in the upload area and depends on the server settings. Very long videos are better trimmed first.
Will the quality change?
If you keep the original format the audio is copied without re-encoding. Converting to MP3 or another format re-encodes it at a high bitrate.
Do you keep my files?
No. Files are stored temporarily under a random token and deleted after download or after one hour at most.
