MP4 is a container: it may include a video track and an audio track. This tool reads the first audio track and exports MP3 for listening or PCM WAV for editing. Set a start and end time to keep only the sound you need.
Start 12, end 18 → the six-second audio section from your video.
Give your idea its next scene.
AI generation has separate account and credit requirements.
Good to know
Does MP4 to MP3 keep the video?
No. The exported file is audio only. Your original video is not modified. Choose WAV if you want uncompressed audio for further editing.
Can I extract audio from a silent video?
No. A file must contain a decodable audio track. Muted playback alone does not tell you whether a track exists; the tool checks the file before processing.
Do my files get uploaded?
Your chosen files and entered text are processed in this browser. They are not uploaded to Montagea. Signing in verifies your account. AI tools download models; image-to-prompt downloads its pinned model files from Hugging Face.
Is the download free?
Yes. Sign in with your Montagea account to use these tools, copy results and download files. They cost no credits and add no watermark.
