Remove background noise from any recording or video.

Drop an audio file or a video and get a clean version back — hum, hiss, fans, traffic and keyboard noise removed on our own hardware. Video in, the same video out with the noise gone from the audio. No limits, no account. Heavy echo is reduced, not fully erased.

Noise removal: Start balanced; go stronger if noise remains, gentler if the voice sounds over-processed.

How it works

1. Drop a recording or video

Any common audio or video file — MP3, WAV, M4A, MP4, MOV, MKV. Cleaning starts immediately: no account, no e-mail, no trial.

2. The AI removes the noise

DeepFilterNet3, a speech-enhancement model, separates your voice from the background on our hardware and suppresses the noise while keeping the voice natural.

3. Compare & download

Play the before/after right in your browser, then download the cleaned file as MP3 or lossless WAV. Uploaded a video? You also get your video back with the clean audio in it — the picture is copied across untouched, never re-encoded. Your upload is wiped automatically.

What people clean up

Podcasts

Room & mic noise

Take out fan hum, computer whir and background hiss so a home-recorded episode sounds closer to studio.

Meetings

Zoom & call recordings

Clean up a recorded call or interview before you transcribe or publish it — traffic, typing and street noise removed.

Video

YouTube clips & vlogs

Drop the video itself. CleanGrab cleans the voice and puts it straight back into your file, so you download a finished video — no editor, no re-export, no quality loss on the picture.

Guides

Remove noise from a recording

Every noise type it handles — hum, hiss, fans, traffic, keyboards — which strength to pick, how to clean a Zoom or Teams call, and what to do when the result isn't right.

Remove background noise from a video

Cleaning the sound inside a video file without a video editor: why the picture stays untouched, which formats work, and where noise removal runs out of road.

Clean up audio for a YouTube video

Room noise, fan hum and traffic in vlogs, talking-head clips and screen recordings — where this fits in your workflow, and why YouTube won't fix it for you.

A free Adobe Podcast alternative

An honest comparison with Adobe Podcast, Krisp and Cleanvoice: where CleanGrab wins, and where we're not claiming to.

Background noise in an audio file

What Gentle, Balanced and Strong actually change in decibels, which noise the model was built for, and which noise no amount of processing will remove.

Hum and hiss

Where a 50/60 Hz buzz and microphone hiss come from in your own setup, and five things that fix them at the source in half a minute.

A Zoom or Teams recording

Why per-speaker tracks beat one mixed file, and which artefacts the calling platform already baked in before you got the recording.

Good to know

Is it really free and unlimited?

Yes: no account, no watermark, no daily or monthly cap. Where Adobe Podcast, Krisp and Cleanvoice limit you to an hour a day or month, CleanGrab has no time limit and adds no jingle. The ads around the tool keep the servers running.

What noise can it remove — and can it fix echo?

It removes background noise well: hum, hiss, fans, air conditioning, traffic and keyboard clatter, while keeping the voice. Heavy echo and reverb are a harder, separate problem — CleanGrab reduces light echo but will not fully erase a very reverberant room. We would rather say that than promise something the tool can't do.

Can I clean the audio in a video?

Yes, and you get the whole video back — not just a loose audio track. Drop in an MP4, MOV, MKV or WEBM and CleanGrab lifts out the audio, removes the noise, and puts the clean track back into your file. The picture is copied across bit-for-bit and never re-encoded, so the video quality is exactly what you uploaded. You still get the MP3 and WAV as separate downloads if you want to drop the audio into an editor yourself.

What happens to my file?

Your upload is deleted the moment it has been processed, and the cleaned file is wiped within 45 minutes. Nothing is stored, shared or used to train anything — see the Privacy Policy.

Which model does it use?

DeepFilterNet3, a strong open-source speech-enhancement model, on our own hardware. That is exactly what lets us keep it free and unlimited where others charge or cap you.

Does it work on music?

It's tuned for voice and speech (podcasts, interviews, voice memos, calls, lectures). On music the result may be poor, and the tool will tell you when it couldn't detect clear speech instead of handing you a mangled file.

Got audio to split or transcribe too?

Same family: StemGrab splits songs into stems and ScribeGrab turns speech into text and subtitles — both free. The whole family lives at Shinobi Tools.
