Remove Background Noise from Video

Clean up video audio in one click — no uploads, no accounts, no waiting.
This extension uses on-device AI noise suppression to remove hiss, hum, fans, keyboard clicks, and room noise from your video files. Processing happens right in your browser and can run up to 10× faster than real time, so a 20-minute video can finish in ~2 minutes.*

✨ Key features
- One-click cleanup — choose a video and press Process Media
- Fully on-device — your files never leave the browser; no server uploads
- Super fast — up to 10× faster than playback (hardware-accelerated/WASM)
- AI noise suppression — removes background noise while preserving voices
- Wide format support — works with common containers/codecs (MP4, MOV, MKV, WebM, etc.)
- Preview before export — A/B toggle to compare original vs cleaned audio

┃ *Actual speed depends on your CPU/GPU, browser, and file length/codec.

💡 How it works
- Open the extension and choose your video file.
- Click Process Media to start processing (on-device).

🔐 Privacy & permissions
- On-device processing only — the extension does not upload or send your media anywhere.
- Minimal permissions: file access for the items you open, and download permission to save results.

🛠 Troubleshooting
- File won’t open? Convert to a common format (MP4 H.264/AAC or WebM VP9/Opus) and try again.
- No sound in export? Make sure the source file contains an audio track.
- Slow on large files? Close heavy tabs/apps, or export audio-only for a lighter workflow.
- Browser memory limits: extremely long or high-bitrate files may need to be split before cleaning.
