Remove Audio from Video — Online Tool

No. By default we use lossless stream copy — the audio track is stripped without re-encoding the video. The result is byte-for-byte identical video quality. Re-encoding only happens if you choose to convert to a different format.

Select "Same" as the output format. This uses stream copy which removes the audio metadata without decoding or re-encoding the video data. The process is nearly instant even for large files.

Yes. Toggle "Save audio to file" and choose a format: keep the original codec (e.g. AAC → M4A) or convert to MP3, WAV, FLAC, or OGG.

Not if you leave the output format on "Same". The audio track is dropped and the video stream is copied across byte for byte, so a two-hour recording is done in seconds and the image is bit-identical to what you uploaded. Choosing a different container forces a re-encode instead — the picture is then rebuilt, which costs time and a little quality.

Almost certainly, and this is the operation where length matters least: with the format left on "Same" the video is copied rather than decoded, so the tab holds very little at any moment. What sets the real ceiling is the device — the page measures your machine when you pick the file and names your own limit if it will not fit, rather than failing halfway.

Yes — switch on "Save audio to file" and the track you strip out is handed to you as a separate file instead of being thrown away. You can keep it in its original codec, which costs nothing and loses nothing, or convert it on the way out when you need a plain MP3 to hand to someone.
