How to Remove Audio from a Video

Sometimes you want video without sound — silent posting to social media, replacing the audio track with music, or stripping audio for privacy. Every modern phone and OS supports this.

On iPhone (Photos app)

1. Open the video in Photos
2. Tap Edit
3. Tap the speaker icon (top left) → turns yellow with a slash through it
4. Tap Done
5. Save (replaces or saves as new)

The video now has no audio.

On Android

Google Photos:

1. Open video
2. Tap Edit
3. Tap audio icon → mute
4. Save copy

Samsung Gallery: similar workflow in built-in editor.

Other Android: most gallery apps have a mute feature; if not, use a free editing app like CapCut.

On Mac (iMovie)

1. Open iMovie, create new project
2. Drag in video
3. Click the audio track (typically below the video on timeline)
4. Press Delete to remove audio
5. Or: lower volume to 0 via inspector
6. Export

On Mac (QuickTime)

1. Open video in QuickTime Player
2. Edit → Remove Audio
3. File → Save As

Fast and simple for single videos.

On Windows (Clipchamp)

1. Open Clipchamp (built into Windows 11)
2. Drag in video
3. Click audio in timeline → set volume to 0 (or right-click → Delete)
4. Export

On Windows (Photos app)

1. Open video in Photos
2. Edit & Create → Edit
3. Audio controls in the edit panel
4. Mute, save copy

Cross-platform: CapCut

CapCut (free):

1. Import video
2. Click audio track → delete
3. Or set volume to 0
4. Export

Command-line: FFmpeg

For batch processing or precise control:

Remove audio (silent video):

ffmpeg -i input.mp4 -c:v copy -an output.mp4

-an means “no audio.” -c:v copy keeps the video stream without re-encoding (fast).

Mute audio but keep the track (silent audio track):

ffmpeg -i input.mp4 -c:v copy -c:a aac -af "volume=0" output.mp4

Some platforms require an audio track even if silent; this satisfies that.

Why “mute” vs “remove”

Remove audio: the file has no audio track at all. Smaller file, simpler.

Mute audio: silent audio track present. Same file size, but some players prefer it.

For most uses: removing is fine. For platforms that need an audio track for upload: keep silent track.

Common scenarios

Posting to silent autoplay social platforms: many platforms (Twitter feed, Facebook) autoplay video silently. Adding back-burned subtitles + removing audio creates a clean experience.

Replacing soundtrack: remove original audio, then add music — see Add Music to a Video.

Privacy / confidentiality: ambient conversation captured accidentally; remove before sharing.

Bad audio quality: tinny phone audio, wind noise; replace with silence or new audio.

Music copyright issues: original audio might infringe (someone singing copyrighted song); remove and replace with royalty-free.

Educational/professional videos: focus on visual content only.

Extracting audio (the opposite)

If you want to KEEP the audio (separate from the video):

Just the audio: see MP4 to MP3 — extracts audio as MP3 file.

Audio + silent video:

1. Extract audio with MP4 to MP3
2. Remove audio from video (this guide)
3. Now you have both separately

After removing audio

Add new audio:

• iMovie / CapCut / Clipchamp / FFmpeg can layer in new music or narration
• See Add Music to a Video

Add subtitles:

• See Add Subtitles to a Video — important for silent video

Add text overlays:

• See Add Text to a Video

Compress:

• See Compress Video

File size impact

Removing audio:

• Audio is typically 5-10% of total file size for normal phone video
• For 100 MB video: removing audio → ~90-95 MB
• Not a major reduction but every bit helps for email

For real size reduction, also compress: see Compress Video.

Quality considerations

When removing audio:

With -c:v copy (FFmpeg): zero quality loss; video stream isn’t touched.

With re-encoding tools (most GUI editors): video may be slightly re-compressed. Minor quality loss possible.

For pristine quality removal: FFmpeg with -c:v copy is the fastest and lossless option.

TL;DR

• iPhone: Photos → Edit → tap speaker icon to mute → Done
• Android: Google Photos or Samsung Gallery → Edit → mute
• Mac: QuickTime → Edit → Remove Audio, or iMovie for more control
• Windows: Photos or Clipchamp
• Cross-platform: CapCut
• Command-line (lossless): ffmpeg -i input.mp4 -c:v copy -an output.mp4
• For extracting audio first: MP4 to MP3
• After: add new music (Add Music to a Video) or subtitles (Add Subtitles)
