Free 30 second preview · No upload

Your file never leaves this browser. The 30 second preview runs on your own device — nothing is uploaded, nothing is stored, nothing is used for training.

How it works

Four steps, none of them an upload

  1. Pick a file

    Drop in audio or video. Your browser reads it where it already sits — there is no upload step, so there is nothing to wait for and nothing to trust us with.

  2. The engine comes to you

    About 9 MB of WebAssembly, fetched only once you actually pick a file. This page itself stays light; the noise removal model is what arrives at that point.

  3. Cleaned on your own device

    We take a representative 30 second window and run DeepFilterNet 3 over it locally. On a recent phone that is a few seconds of work — your hardware, not our servers.

  4. Compare, then download

    Switch between the original and the cleaned version on one player, try a different preset as often as you like, and download the preview.

Cleaning a complete file is not live yet — the 30 second preview is the whole tool today

Pricing

Free. There is nothing to buy.

You find out whether this works on your recording without any money involved, because the preview costs us nothing to give you — it runs on your hardware.

Cleaning a complete file

This does not exist. When we build it we will probably charge for it, but no price has been set, and we are not going to print one here before the thing is real.

It may also need to send your file to a server, unlike the preview. We will say so on the privacy page before that ships, not after.

FAQ

The questions worth answering honestly

Does my file get uploaded?

No. Your browser opens the file locally and the noise removal runs on your own device, so there is no upload step to opt out of. That also means your audio is never used to train anything: we could not, because we never receive it.

Then why does it download about 9 MB?

Because the engine has to come to you rather than your file going to it. That download is the noise removal model itself, and it only starts once you pick a file — landing on this page does not fetch it.

Which files can I use?

Audio or video: mp4, mov, m4a, mp3, wav, aac and most things alongside them. With a video we take the audio track and leave the picture alone. If your browser cannot decode a particular file, converting it to mp3 or wav first almost always works.

Why only 30 seconds?

Because it is enough to hear whether the noise is gone and whether the voice survived it, on your own recording rather than on a demo we chose. Cleaning a complete file is not built yet.

Is it free?

This version is free, and there is nothing to buy: no account, no card, no email. Cleaning a complete file does not exist yet, and when we build it we will probably charge for it — but no price has been set, and we will not print one before the thing is real.

Will it always sound better?

No, and you should not take our word for it either way — that is what the A/B player is for. Noise removal is lossy: the stronger settings in particular can leave a voice sounding thin or metallic. If the balanced preset already sounds right, use it.

Which browsers work?

We test in Chrome and Safari, including Safari on iPhone, where a 30 second preview takes a few seconds. Other Chromium browsers such as Edge use the same engine as Chrome. We have not tested Firefox yet.
