ViralMint pulls the audio track out of any video — MP4 to MP3 in seconds, processed locally with FFmpeg, with no upload and no length limit.
Free and unlimited — no account, no watermark, and the file never leaves your browser. Big files and batch runs are faster in the desktop app.
Most converters blindly re-encode to MP3 and lose quality. ViralMint can copy the original AAC track into an M4A container untouched — bit-for-bit the audio the video shipped with — or transcode to MP3 when you need maximum compatibility.
A 3-hour podcast recording extracts in seconds because nothing is uploaded — FFmpeg reads the file straight off your disk. Online converters choke on big files or paywall anything over ten minutes.
Paste a YouTube, Twitch or podcast-episode URL and ViralMint downloads the audio-only stream directly — smaller, faster, and it recovers automatically from the HTTP 403s that break browser extensions.
Launch ViralMint and open Tools → Extract Audio.
Use any local video file (mp4, mov, mkv, webm) — or paste a video URL to fetch the audio-only stream directly.
Choose lossless M4A (original track, no re-encode) or MP3 for maximum compatibility.
The file lands in your library — ready for a podcast edit, a transcription, or the music visualizer.
Open the video in ViralMint's Extract Audio tool and choose M4A or MP3. The extraction runs locally with FFmpeg, so it's free, works offline, and has no file-size or length limit — a 3-hour recording takes seconds because nothing is re-encoded unless you ask.
Only if you re-encode. Most videos carry AAC audio, which ViralMint can copy losslessly into an M4A file — identical quality to the source. Choose MP3 only when a device or editor requires it; that pass re-encodes at 192kbps.
Paste the URL and ViralMint downloads the audio-only stream via its yt-dlp engine — no need to download the full video first. Stick to your own uploads, licensed material and content the platform's terms allow.
Everything stays in one app: clean it up with the audio enhancer, cut silence and filler words, transcribe it with local Whisper, or turn it into an animated music-visualizer video.
The Extract Audio from Video ships inside the free ViralMint desktop app — no subscription, no watermark, no per-minute cap. Download once, use on as many videos as you want.
