1Upload the videos whose soundtrack you want gone.

4Download the silent Video file, which is also smaller than what you started with.
Mute Video FAQ
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.
How does Mute Video remove the sound?
+
Concretely, the audio track is removed at the container level and the picture is copied without re-encoding, whatever the clip length. The result is the same picture with no audio track at all, rather than an audio track turned down to zero.
Anything specific to Video worth knowing?
+
Yes — the container and codec are probed before anything runs, so mixed uploads in one batch are handled per file. Relevant when the source has more than one audio track.
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.
Is there a file size limit on Mute Video?
+
Yes: free accounts process video up to 40 MB per file whichever container you brought; ffmpeg with x264, x265 and libvpx does the encoding. It is high enough that upload speed is usually the binding constraint rather than the cap itself.
Can I run Mute Video on several videos at once?
+
Yes, and it matters here more than anywhere else — video jobs run in minutes, so queueing the batch in parallel is the difference between one wait and several.
Why does a EPUB site host Mute Video?
+
EPUB.to is built around the open eBook format — XHTML in a zip, reflowable by design, and readable on hardware nobody has thought about the layout for. A book is a zip full of markup, images and fonts, so almost every job people bring to an eBook site is really a job on one of those things. Mute Video runs on the same upload and the same account as the conversions because that is where it is needed.
What should I do with the result once Mute Video is finished?
+
The converter on this site moves books between EPUB, MOBI, AZW3, PDF and DOCX, so a title ends up on whatever hardware is actually going to read it. Doing that after Mute Video means the conversion is made from the version you settled on, not from the one you were still fixing.
Is Mute Video here the same tool the sibling sites run?
+
The engines are shared — the same toolchain, the same workers, the same limits. What a EPUB site adds is a view on reflow: which of these operations a reflowable book genuinely supports, and which ones only make sense on the fixed-layout media inside it. It also starts from one fact about the format this site is named after: the book is a zip of XHTML with a manifest, so the text costs almost nothing and every decision that matters is about the embedded images and font subsets.
Do I need an account, and does anything get kept?
+
No account is needed. Uploads and results are kept for about 24 hours, which leaves time to download the result, and are then deleted automatically; nobody reads, lists or indexes them. Several files in one job need a paid plan.
