Häufig gestellte Fragen
Can I convert MP4 to MP3 online without uploading?
Yes. This tool runs FFmpeg WASM inside your browser. Drop in an MP4, WebM, MOV, or MKV — the audio is extracted and encoded to MP3 locally. Open DevTools → Network tab to verify zero uploads.
What bitrate does the output MP3 use?
Default is 192 kbps CBR — a good balance between file size and quality. For voice-only recordings, 128 kbps is enough; for music, 320 kbps is transparent.
Why extract audio instead of using a YouTube converter?
Most "YouTube-to-MP3" sites are sketchy ad-laden services that require uploads and sometimes violate platform terms. This tool converts video files you already have (from a phone, camera, or download) — it does not touch YouTube or any streaming service.
Can I choose WAV or AAC instead of MP3?
Yes. Use the format dropdown above to switch between MP3 (192 kbps), AAC (M4A, 192 kbps), or WAV (uncompressed, best for editing).
What is the max file size?
Limited by browser memory — typically up to 2 GB. For long podcast or lecture recordings over 2 GB, trim them in the Trimmer tool first.
