Why edit a video's audio track
Mute a video completely
One toggle, Disable audio track, hands back the same video with no sound in it at all. Nothing else about the file is changed.
Rebuild the sound, keep the video
Set the audio codec, the bitrate, the sample rate and the channels. The output is still a video, so it plays exactly where the original did.
Ten containers to choose from
MP4 is the default, and MKV, MOV, AVI, WEBM, WMV, FLV, OGV, 3GP and 3G2 are all one pick away in the settings panel.
Every audio setting the engine accepts
Codec is the format the track is re-encoded with. For an MP4 that is aac, ac3, eac3, he-aac v1, he-aac v2, mp2, mp3, opus, vorbis or copy. Bitrate runs from 8 to 320 kbps: higher means better sound and a bigger file. Sample rate runs from 8000 to 96000 Hz, where 44100 Hz is CD quality and 48000 Hz is the usual figure for video. Channels is stereo or mono.
Every one of those lists is read per container, not typed once, so you are only ever offered values the chosen output actually accepts. A container that does not accept a setting at all simply does not show it: 3GP has no bitrate control, because 3GP has no bitrate to set.
Leave a setting untouched and it is not sent, which means the container's own default is used.
The settings sit in the panel beside the uploader, and only appear once there is a file to apply them to.
Silence a track, or pass it through untouched
Disable audio track is the mute switch. Turn it on and the audio settings step aside, because there is no longer a track to encode: what comes back is the video with its sound removed.
Copy is the opposite move. Pick it under Codec and the existing audio is carried into the new file as it is, with no second round of encoding. That is the setting to use when the only thing you want to change is the container.
You can add several videos at once. Each one is processed on its own with the same settings and comes back as its own file.
Disable audio track removes the sound. Copy keeps it in the new file as it is.
Free to use, and private by default
Editing the audio track of a video is free and needs no account. Every upload and download runs over an encrypted connection, so your footage cannot be read on the way.
Processing is fully automated: nobody watches your videos and they are never used to train AI models. You keep the copyright and the ownership of both the video you upload and the one you get back.
The servers that do the work are in Europe.

Questions about editing a video's audio
How do I remove the sound from a video?
Upload the video, switch on Disable audio track in the settings panel and start. The video comes back without its audio track, and the picture is left as it was.
Can I change the audio without re-encoding it?
Yes. Choose copy under Codec and the existing track is carried straight into the new file, so nothing is encoded a second time. Use it when you only want a different container.
Which output formats can I choose?
MP4, MKV, MOV, AVI, WEBM, WMV, FLV, OGV, 3GP and 3G2. MP4 is the default and is the one that plays on the widest range of devices and players.
What bitrate and sample rate should I pick?
A higher bitrate sounds better and makes a bigger file, so the choice is a trade-off rather than a right answer. 44100 Hz is CD quality and 48000 Hz is the usual sample rate for video; stereo suits music and mono is enough for a voice recording. If you are unsure, leave the setting alone and the container's default is used.
Can I edit several videos at once?
Yes. Add as many as you like and each one is processed separately with the same settings, then returned as its own file.
Does it cost anything?
No. Editing the audio track of a video here is free and does not require an account. A paid plan raises the upload limit and how many files you can process at once.
