100% private. FFmpeg runs inside your browser (WebAssembly), so the video is never uploaded. The first run downloads the engine once (about 30 MB) - after that it is cached.

Audio Extractor FAQ
No. Everything runs entirely inside your browser using WebAssembly (FFmpeg.wasm). Your video file is read locally and never transmitted over the internet. This makes the tool safe for private recordings, corporate content and personal videos.
MP3 is the best choice for general use - it is universally compatible and produces small files. Choose WAV or FLAC if you need lossless quality (e.g. for music production). AAC and M4A offer better quality than MP3 at the same bitrate and work well on Apple devices. OGG Vorbis is a free, open format with excellent quality.
The tool supports all major video formats including MP4, MKV, MOV, AVI, WEBM, FLV, WMV, M4V, 3GP, TS and MTS. It also accepts most audio formats for format conversion (e.g. WAV to MP3, FLAC to AAC).
On your first visit the browser downloads and compiles the FFmpeg WebAssembly engine (about 30 MB). It starts downloading as soon as you pick a file and is cached afterwards, so later runs start almost instantly. Processing speed also depends on the length of the video and your device's CPU - the Original option is the fastest because nothing is re-encoded.
The tool is limited only by the available memory in your browser. Most modern browsers handle files up to several gigabytes, though very large files may be slower to process. For files over 2 GB we recommend a desktop app such as HandBrake or VLC Media Player.
Yes. Choose Original and the audio track is copied exactly as it is stored in the video - no quality loss, and it finishes in seconds even for long films. Most MP4 videos give an M4A (AAC) file, WEBM videos give OPUS or OGG, and some MKV files give AC3 or FLAC.
Yes. Open Trim, type a start and an end time such as 1:30 and 2:45, then extract. Only that part is saved, which is handy for a song from a concert video, a quote or a ringtone.
Selecting Mono merges both audio channels into one, which roughly halves the file size compared to Stereo. It is useful for voice recordings, podcasts and speech where stereo separation adds no value.
