Why did the first video tool I used take longer to load?

The first time you use any video tool on this site, your browser downloads a small video-processing engine (about 25MB). After that, it's cached, and every video tool — including this one — loads instantly.

Which output formats can I pick?

MP3, WAV (uncompressed), M4A (AAC), OGG and FLAC, plus Original audio. The lossy ones are encoded at high quality: MP3 at VBR level 2, OGG at quality 5 and M4A at 192 kbit/s. WAV and FLAC are lossless.

What exactly does Original audio do?

It copies the sound track without re-encoding. AAC becomes .m4a, MP3 stays .mp3, Opus becomes .opus, Vorbis becomes .ogg and FLAC stays .flac. If the track uses any other codec, the tool saves an MP3 instead and shows a notice.

How do I extract just one section?

Tick Extract a specific time range instead of the whole video. Drag both slider handles or type Start and End. The start must be earlier than the end, and times beyond the video length are clamped to its end.

What if my video has no sound?

You are told as soon as the file loads: This video has no audio track, with a note that nothing was used from your trial, and Extract Audio stays off. MP4, MOV, WebM and MKV are checked from the file itself; for other containers the same message appears when you press Extract Audio, instead of the button doing nothing.

Can I take the audio from several videos at once?

Yes. Choose Several videos (ZIP) at the top, pick Save as once, and drop the videos. Each is extracted with that format and you download one ZIP; a video with no sound is marked on its own row and does not stop the others. The whole batch counts as one use, taken when you download (one file or the ZIP) and never when you press Extract all or if every video fails; up to 5 videos on the trial, more on a paid plan. The time range applies to one video at a time.

Why was my file refused?

Files that look like audio (mp3, wav, flac, ogg, m4a, aac, opus) are rejected because there is no video to take sound from. A file whose type is not a video is also turned away. Drop an MP4, MOV, WebM, MKV or similar.

Why is the first extraction slower?

The FFmpeg engine, about 25 MB, has to be fetched before work starts, and the status line says so. Later runs can reuse your browser's cached copy, but how quickly that happens depends on your browser and network.

About Extract Audio

Pulls the audio track out of a video file and saves it as a standalone MP3, WAV, M4A, OGG or FLAC file (or copies the original audio untouched), useful for turning a recorded video into a podcast-style audio file or just keeping the sound without the visuals. Optionally extract just a specific time range instead of the whole video. Runs entirely in your browser — the video never leaves your device.

How to use Extract Audio

Drop a video file; audio files are turned away with a note pointing elsewhere. The preview player loads, but nothing is converted until you press Extract Audio, so start with the Save as menu and choose MP3, WAV (uncompressed), M4A (AAC), OGG, FLAC or Original audio (no re-encode, instant).

To keep only part of the sound, tick Extract a specific time range instead of the whole video, then drag the slider or type Start and End as m:ss or plain seconds, confirming with Enter or by clicking away. A line beneath shows how much will be taken. A video with no sound track is reported the moment it loads and Extract Audio stays off. To take the sound from many videos, choose Several videos (ZIP) at the top: they share one Save as setting and come back as one ZIP. Press Extract Audio, listen to the preview that appears, and use the Download button, which is labeled with the chosen format.

When to use it

Good for turning a lecture, interview or conference talk recorded as video into an audio file you can play on a commute, keeping the narration from a screen recording, or saving the sound of a clip you filmed yourself. The time range option spares you converting an hour of video when only one section matters.

When not to use it

Do not expect it to separate voices from music, remove noise or repair a poor recording; it takes the existing sound track as it is. A file that is already audio is rejected, and the Audio Trimmer or an audio converter is the right tool for it. Only extract sound you have the right to reuse.

Tips for best results

Choose Original audio when you want no quality loss and an instant result. It copies the track unchanged into a matching file type when the video holds AAC, MP3, Opus, Vorbis or FLAC audio, and falls back to MP3 with a notice otherwise. For the lossy choices the tool always uses its highest quality setting, so pick WAV or FLAC only if you truly need lossless, and expect WAV files to be large.

Limitations

Only the first audio track is taken, so a video with several language tracks yields just the first. A video without sound is reported at once with a clear message instead of an empty file or a button that does nothing. The time range works on one video at a time, not in a batch. The whole video is loaded into browser memory, so very large files can fail on low-memory devices, and some phone .mov files use a codec the engine cannot decode.

Privacy

Extraction runs through FFmpeg compiled to WebAssembly inside your browser tab, so the video file stays on your device. The engine itself, roughly 25 MB, is fetched from the jsDelivr CDN the first time an audio or video tool needs it. The resulting audio is created in memory and is only written to disk when you click Download.
