How do I remove background noise from a video for free?
Open the video in Cutmallow and turn on Remove background noise. The audio is cleaned on your own device: Clean mode works instantly on any phone, and Studio mode uses the DeepFilterNet3 noise-suppression model for heavier noise. Listen to the before and after, set the strength, and export the video with clear sound. It is free, unlimited and nothing is uploaded.

How to do it in three steps
Drop your video into the editor. It opens on your device, nothing is uploaded.
Turn on Remove background noise. Listen before and after, and set the strength.
Export a 9:16 MP4 with the clean sound.
Then keep going in the same place: add captions, zooms and a style, so the Short is finished before you leave the page.
How it works
Clean mode estimates the steady noise under your voice and subtracts it, which is fast enough for any phone. Studio mode runs DeepFilterNet3, an open-source neural network trained to separate speech from noise at full 48 kHz quality, inside your browser.
Most online noise removers upload your file and charge by the minute once a short trial runs out. Here the processing happens on your device, so there is no queue, no minute limit, and the recording never leaves your hands.
Tips for a better result
- Start at medium strength. Too much can thin out a voice; the before / after switch makes it easy to judge.
- Use Studio for wind, crowds and loud fans; Clean is enough for a quiet room hum.
- Clean the sound before adding music: music added afterwards is never touched.
One flow instead of three apps
Every free tool here opens the same Cutmallow editor, so the whole Short gets finished in one place.
- Pauses, noise and captions in one editor, instead of a different app for each job.
- Private: the video is processed on your device and never uploaded.
- Works on phones as well as laptops, in the browser you already have.
- No credits, no usage limits, no watermark.
Frequently asked questions
Something else? Write to [email protected].
What kind of noise does it remove?
Steady sounds behind your voice: fans, air conditioning, traffic and electrical hum. Music you add later is not touched.
Will my voice sound robotic?
You set the strength, and you can listen to the original and the cleaned sound side by side before you export.
Is the audio sent to a server?
No. The noise model runs in your browser. Your video never leaves your device.
How long can my video be?
Up to 15 minutes. Most Shorts and Reels are well under that, so you can drop a whole take and keep the best part.
Does it work on my phone?
Yes. It runs in Safari on iPhone and in Chrome on Android, as well as Chrome, Edge, Safari and Firefox on computers. An older phone takes longer, because your own device does the work.
Is there a watermark or a paid plan for this?
No. The export is clean, in full quality, with no account. Cutmallow runs on your device, so there are no server bills to pass on.
