How It Works
Pulling audio out of a video should be quick and private. Focera keeps the whole flow on one page — upload, choose quality, convert, and download without an account or desktop installer.
- Upload your video. Drag and drop an MP4, WebM, or MOV file up to 100 MB and 10 minutes, or click the zone to browse from your device.
- Pick MP3 quality. 128 kbps saves space, 192 kbps is a solid default, and 320 kbps keeps the most detail.
- Convert and download. Processing runs in your browser. Preview the audio, then save the .mp3 file.
Jump back to the MP4 to MP3 converter anytime to process another file.
