To remove audio from a video, open it in a mute tool, choose to remove the audio track and export: the picture is copied into a new file that simply has no soundtrack. Done properly it takes seconds and costs nothing in quality, because not one video frame has to change. The decisions that matter come before the button — no track or a silent one, the whole clip or one sentence, and whether the sound is being deleted or replaced.
Removing sound should not touch the picture
A video file is a container holding separate streams: one for the picture, usually one for the sound, and an index saying where each piece sits in time. A compressed frame of video has no idea whether there is a soundtrack beside it. So removing the audio does not require decoding anything — the video packets are copied into a new container byte for byte, and the new index just does not list an audio stream.
That has three practical consequences. There is no generation loss, because the compressed picture is never opened. It is fast, limited by how quickly the file can be read rather than by encoding. And the file gets smaller, never larger — a tool that re-encodes the whole clip just to drop the sound can easily hand back something softer and heavier than you gave it.
The mute tool copies the picture in all but two situations, both of which you choose: an output container that cannot hold your video codec (WebM carries only VP8, VP9 and AV1, so an H.264 or HEVC clip has to be converted to go in), and an exact-start trim, which re-encodes so the cut lands on the precise frame.
Remove the track, or replace it with silence?
These sound identical and produce different files. Removing leaves a picture and nothing else. A silent track keeps an audio stream in the file, filled with digital zeros.
| Remove all audio | Replace with a silent track | |
|---|---|---|
| What the file contains | A video stream only | A video stream plus an audio stream of pure silence |
| File size | Smallest possible | Very slightly larger — encoded silence is tiny, not zero |
| In a player | Some players hide or grey out the volume control | A working volume control that plays nothing |
| Use it when | Almost always: sharing, autoplay, voiceover prep | An editor, scheduler or delivery spec rejects files with no audio |
Removing is the right default. The silent track exists because some editing software, broadcast specifications and upload pipelines treat a video with no audio stream as malformed. If an import failed for that reason, the silent track is the fix — it matches the source's sample rate and channel count, so nothing has to be converted on the other side.
The workflow
Save the sound first if you might want it
Deleting the audio is permanent in the exported file. If there is any chance you need it, extract the audio to MP3, WAV, FLAC, OGG, AAC or M4A first — see pulling the soundtrack out of a video.
Add the clip
MP4, MOV, WebM and MKV all open. The free plan takes one file at a time, up to 300 MB and an hour long; Pro removes the size cap and mutes batches of up to twenty, downloaded as one archive.
Choose what happens to the sound
Remove all audio, silence chosen sections, replace with a silent track, or keep selected tracks on a file that has several.
Keep the output on same as source
The panel beside the button says whether the picture will be copied or re-encoded before you press anything.
Play it back before you share it
The tool re-opens the finished file and counts its audio streams, but a ten-second listen is still the best check.
Strip the soundtrack and keep the picture exactly as it was. It all runs on your device, not our servers, so a long clip is limited by your machine rather than an upload.
Mute a videoMuting only part of a clip
Often you only need to lose a cough, a swear word, a phone ringing halfway through, or a piece of background music you cannot clear. Choose Silence chosen sections, add a range for each stretch with a start and end in seconds, and everything outside those ranges comes through exactly as recorded. The free plan allows three ranges per clip; Pro allows fifty.
Each range gets a short fade at both edges — 10 ms by default, adjustable from zero up to a quarter of a second — because dropping a waveform to zero mid-cycle is heard as a click. Overlapping ranges are merged, so two spans drawn across the same moment do not leave a blip between them. The cost: changed samples cannot be copied, so the audio is re-encoded. The picture is still copied untouched.
If the footage under the unwanted sound is not worth keeping either, cut it out instead with the video cutter — trimming without re-encoding explains where those cuts can land.
Removing audio and adding new audio
If the plan is a new soundtrack, there is no need to mute first and add music second. Replace audio does both in one pass, and copies the picture rather than re-encoding it. Replace drops the original track entirely; Mix keeps it underneath at a level you choose, so music sits behind dialogue — 25–40% is the usual starting point.
You can loop the new audio to fill the video, play it once and let the rest run silent, or cut the video where the audio ends, then add fades and nudge the sync. The free plan takes videos up to 200 MB and ten minutes, audio files up to 50 MB and fades of up to ten seconds; Pro adds batches and a higher-quality 48 kHz export. Stitching several clips together afterwards brings its own audio traps — see merging videos into one file.
When a platform mutes it for you
Some muting happens after upload, by copyright systems. On YouTube, at the time of writing, a creator whose video is claimed for music can trim out the claimed segment, replace the song with a track from the YouTube Audio Library, or erase the song — which either mutes just the claimed song and leaves dialogue alone, or mutes all sound in the claimed segments. YouTube is explicit that the claim stays if any claimed content remains (YouTube Help).
Doing it yourself before uploading gives you control over exactly which seconds go quiet, how the fades sound and what replaces the music. It does not grant you any rights: removing the claimed audio is what matters, and anything you add in its place needs to be licensed too.
Removing audio from an iPhone video
According to Apple, at the time of writing an iPhone records video as HEVC under the default High Efficiency camera setting, and as H.264 under Most Compatible. Both copy straight into MP4 or MOV, so keep the output on same as source and the picture is untouched. Choosing WebM forces a full conversion, since WebM cannot hold either codec.
Frequently asked questions
How do I remove audio from a video for free?
Add the clip to the mute tool, choose Remove all audio and export. The free plan handles one video at a time, up to 300 MB and an hour long, and the picture is copied rather than re-encoded, so the result looks identical to the original.
Does removing audio from a video reduce the quality?
Not when the picture is copied. Sound and picture are separate streams, so the audio can be dropped without decoding a single frame. Quality only changes if you pick an output container that cannot carry your video codec, or tick exact start on a trim.
Can I remove audio from a video without a watermark?
Yes. The compressed picture is copied into the new file byte for byte, so nothing can be drawn onto it — no watermark, no logo, no change to a single frame.
How do I remove audio from a video and add new audio?
Use the replace audio tool rather than muting first. Replace drops the original track and puts yours in its place; Mix keeps the original underneath at a lower level. You can loop, fade and offset the new track, and the picture is still copied untouched.
Why does my muted video still show a volume icon?
Many players draw a volume control whatever the file contains. If you chose a silent track, the file genuinely has an audio stream — it is just full of zeros. Choose Remove all audio for a file with no audio stream at all.
