Our pick for iPhone
Noise Reducer does one thing: it removes noise around a voice. Because it never re-encodes the picture, it is also fast, and because it runs offline, your videos never leave the phone. You can hear the full result before deciding to pay.
If you have iPhone 16 or later
Try Audio Mix first for videos you shot yourself with Spatial Audio. It is free and built in. For older videos, videos from other phones or downloads, use an app.
If you edit on a computer
Desktop editors such as iMovie for Mac, DaVinci Resolve and Premiere Pro include noise reduction. They are powerful but take more time than a one-tap app.
Questions and answers
How do I remove background noise from a video but keep the voice?
Use a speech model, which recognises the voice and removes the rest. Noise Reducer does this on iPhone.
Can CapCut remove background noise?
CapCut has a Reduce noise option. In recent versions it is reported to be a Pro feature. See our CapCut guide.
