Background noises like loud fan sounds, traffic, or room echo can easily ruin your screen recordings, interviews, and vlogs. This tool quickly removes all background noise from your video's audio using powerful, smart AI-just like the expensive paid tools, but 100% free and unlimited. Your video files are not uploaded anywhere, and your original video resolution and quality stay exactly the same.
Best for fixing audio in everyday videos where the picture is already perfect:
- Screen recordings and tutorials with annoying background noises like a loud fan or AC hum.
- Vlogs and outdoor interviews recorded in noisy or untreated rooms.
- Webinar and video call recordings that need a clean sound before you publish them.
- Any video where the picture looks great, but the audio needs a quick cleanup.

Frequently Asked Questions
No. Only the audio track is replaced with a denoised version - the video stream itself is copied as-is, with no re-encoding, so picture quality and resolution are completely unchanged.
The audio track is extracted from your video, cleaned using RNNoise (an open-source AI model trained to separate speech from steady background noise), and combined back with the original video. Everything runs locally in your browser.
Yes, completely free with no daily limit and no account. Similar AI-based tools often charge a subscription once a free quota is used up — this runs the same class of noise-suppression model at no cost.
MP4 and WebM are supported for output, matching common input formats like MP4, MOV, and WebM. The audio track is converted to AAC (for MP4) or Opus (for WebM) after denoising.
The audio is downmixed to mono during noise removal, since the underlying model processes a single channel and most spoken-word video (interviews, tutorials, vlogs) is effectively mono content anyway.
It depends on your device and the video's length — processing happens entirely in your browser's CPU, without a server, so it's typically slower than desktop software. Shorter clips (a few minutes) process comfortably; very long or very high-resolution files will take noticeably longer.
No. Audio extraction, noise removal, and recombining with the video all happen locally in your browser. Your video file never leaves your device.
Quick Tips to Get the Best Sounding Videos
While our AI tool can easily fix noisy audio, here are a few simple tricks to make your videos sound even better next time:
- Get closer to the microphone: This makes your voice much louder than any outside sound.
- Turn off loud appliances: Always turn off nearby fans, coolers, or ACs before you start recording.
- Use pillows or curtains: If your room echoes a lot, soft blankets or curtains can help absorb the sound.
- Use our tool for final cleanup: Run your finished video through our free website to clear out any remaining minor noise instantly.
