Frequently Asked Questions
Is this noise remover free?
Yes, 100% free. No signup, no email, no daily limit. Files are processed entirely in your browser.
Does it work with video files?
Yes. Upload MP4, WEBM, or MOV — the tool extracts the audio track, cleans it, and gives you a cleaned WAV file you can attach back to your video.
Are my files uploaded to any server?
Never. All processing uses the Web Audio API inside your browser. Your files never leave your device.
Which audio formats are supported?
MP3, WAV, M4A, AAC, OGG, WEBM, MP4, and any format your browser can decode. Output is always WAV for maximum compatibility.
Does it work offline?
Yes. After the page loads once, disconnect from the internet and the tool still works.
Can it remove background music from a video?
Not currently. Music is treated as part of the audio signal. Vocal isolation would require AI-based source separation.
How do I attach the clean audio back to the video?
Use CapCut (free) — import video, delete original audio, add clean WAV file. Or use FFmpeg command line.
Will it affect my voice quality?
Medium and Light modes preserve voice quality. Strong and Extreme may cause slight artifacts — use only when necessary.
