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.
Any common audio or video file — MP3, WAV, M4A, MP4, MOV, MKV. Cleaning starts immediately: no account, no e-mail, no trial.
DeepFilterNet3, a speech-enhancement model, separates your voice from the background on our hardware and suppresses the noise while keeping the voice natural.
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.
Take out fan hum, computer whir and background hiss so a home-recorded episode sounds closer to studio.
Clean up a recorded call or interview before you transcribe or publish it — traffic, typing and street noise removed.
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.
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.
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.
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.
An honest comparison with Adobe Podcast, Krisp and Cleanvoice: where CleanGrab wins, and where we're not claiming to.
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.
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.
Why per-speaker tracks beat one mixed file, and which artefacts the calling platform already baked in before you got the recording.
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.
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.
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.
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.
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.
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.
Same family: StemGrab splits songs into stems and ScribeGrab turns speech into text and subtitles — both free. The whole family lives at Shinobi Tools.
