How it works
Use the audio noise removal tool to clean a recording. This page explains its four steps, why it is free, and its limits. Other tools have their own workflows and processing details.
How it works
Four steps, none of them an upload
This is the noise removal, start to finish. The voice changer has its own local workflow.
-
Choose a recording
Select an audio or video file, or drag it into the box above. Noise removal reads the file on your device without uploading it.
-
Load the noise reduction model
The browser downloads the model when you choose a file. Wait for it to finish loading before processing starts.
-
Reduce background noise
The model processes the entire audio track on your device. Processing time depends on the recording length and your device’s speed.
-
Compare and download
Switch between the original and cleaned audio. Use the waveform to check a passage, then download the result. Comparison requires the browser to play the original file.
The complete file goes through all four steps on this device — no upload, also free
Pricing
Free. There is nothing to buy.
The complete result is free because the processing runs on your hardware rather than ours.

Cleaning a complete file
The complete file is processed on your own device with nothing uploaded. There is no length limit we impose; practical limits are your device memory, file size and how long processing takes.
We may charge for something later. If that ever happens it will be for something that costs us money to run, it will be obvious which mode you are in, and no price appears on this page before the thing is real.
FAQ
The questions worth answering honestly
Does noise removal upload my file?
No. Noise removal reads and processes your file in your browser. Your recording is not sent to our servers or used to train models. Other tools explain their own data processing before you use them.
Why does the page download model files?
The noise reduction model runs on your device, so your browser needs to download it first. Model loading starts after you choose a recording.
Which file formats can I use?
You can choose MP3, WAV, M4A, AAC, FLAC and OGG audio, or MP4 and MOV video. Compatibility depends on the codec as well as the file type. If a file cannot be opened, try a copy converted to MP3 or WAV.
Does it process the complete file?
Yes. Selecting a file starts complete-file processing immediately. When it finishes, you can play the full cleaned result or download it.
Is the whole recording free to process?
Yes. You can process the entire recording and download the result for free, without an account or payment details. Practical limits depend on your device and browser.
Can noise removal affect the voice?
Yes. It can also remove parts of the voice, leaving it sounding thin, watery or metallic. Compare the original and processed audio before publishing, and keep the source recording.
Which browsers can I use?
Use a recent version of Chrome, Edge or Safari. Export requires AAC encoding support, which depends on your browser and operating system. If the tool reports that the encoder is unavailable, try another browser.
