1Upload the videos whose soundtrack you want gone.
2Confirm that you want the audio track dropped entirely rather than turned down to silence.
3Run it — the track is removed at the container level and the picture is copied through untouched, so it finishes in seconds.
4Download the silent Video file, which is also smaller than what you started with.
Mute Video FAQ
Is the video re-encoded when I mute it?
+
No. Removing a track is a container operation, so the video stream is copied through bit-identically and the job finishes in seconds regardless of how long the clip is.
Does the container format matter?
+
It does. this format is read and written by the same streaming pipeline as everything else we support. That governs how the tracks are stored and therefore how cleanly one can be dropped.
Can I remove just one audio track and keep another?
+
Muting removes the audio entirely. If a file carries several language tracks and you want to keep one, that is a track selection job rather than a mute, and it needs the conversion tools instead.
Should I mute or just silence the audio?
+
Mute. A silent track still occupies bitrate and still has to be decoded by the player; dropping it makes the file smaller and removes any chance of it being unmuted downstream.
Will Mute Video lower the quality of my videos?
+
Only if the operation requires re-drawing frames. Container-level and timeline-level work is done as a stream copy, which is bit-identical to the source and finishes in seconds. Anything that must re-encode does so at a quality level you choose.
What happens to audio, subtitle and chapter tracks?
+
They are carried across wherever the target container can hold them, including multiple audio languages, embedded subtitles and chapter markers, rather than silently keeping only the first track of each.
Does Mute Video cost anything?
+
No. Mute Video is free without an account, and the output has no watermark, corner logo or intro card. Uploaded video is deleted from the workers shortly after the job completes.
Which video formats does Mute Video accept?
+
MP4, MOV, MKV, WebM, AVI, WMV, FLV, 3GP, M4V, MPEG and MPG. Each file is probed for its real container and codec before anything runs, so a mixed batch is handled correctly file by file.
Why does a PDF site host Mute Video?
+
PDF.to exists because PDF is where documents go to be shared and the worst place to keep them while they are still being worked on, so nearly every job here is about getting something into or out of that state deliberately. A document rarely arrives in the state it needs to leave in: it is too big, in the wrong order, locked, or a scan with no text in it. Mute Video sits on the same upload and the same account as the conversions because those jobs turn up together.
What should I do with the result once Mute Video is finished?
+
The converter on this site moves documents between PDF, Word, images, plain text and eBook formats in either direction, so whatever comes out of a tool here has somewhere to go next without a second upload. Running that after Mute Video rather than before keeps the document structure intact through the step that is most likely to flatten it.
Is Mute Video here the same tool the sibling sites run?
+
The engines are shared — the same document toolchain, the same workers, the same limits. What a PDF site adds is a view on when a file should stay a document and when it genuinely wants to become something else, which is the decision most tools quietly make for you. It also starts from one fact about the format this site is named after: a PDF is an object graph, not a page image, so text stays selectable and vectors stay sharp no matter what happens to the raster content inside it.
Do I need an account, and does anything get kept?
+
No account, and nothing is kept: uploads are deleted from the workers shortly after the job finishes, nothing is read and nothing is indexed. Free accounts exist for history and batch size, not for access.
