Drop in a recorded call and get a cleaner voice track back — fan noise, traffic, typing and hum removed before you share or publish the recording. Free, no account.
The cleaned file is the free file. No watermark, no trial length, no account — files up to 45 minutes. A pass adds loudness levelling and a heavier repair pass for rough recordings.

A laptop fan, a passing car, someone typing notes in the same room, the hum of an old monitor — none of it is obvious while you're on the call, but it's all there in the recording. CleanGrab cleans up the voice track from a Zoom, Teams, Google Meet or any other recorded call before you send it on, transcribe it or publish it.
Video-call rooms are notorious for echo — a voice bouncing off a hard-walled room, or a speaker sitting too close to their own speakers. Heavy room echo and reverb are a harder, separate problem: CleanGrab reduces light echo, but it will not fully erase a very reverberant room. We'd rather say that plainly than promise something the tool can't do.
CleanGrab is tuned for voice and speech — podcasts, interviews, calls, voice memos, lectures. On music or other non-speech audio the result can be poor, and the tool will tell you when it couldn't detect clear speech instead of handing you a mangled file.

Yes — CleanGrab accepts common video files as well as audio; it pulls the voice track out, cleans it, and hands back a cleaned MP3 and WAV.

MP3, WAV, M4A, FLAC, OGG, and common video files, up to 45 minutes per upload. You get back a cleaned MP3 (192 kbps) and a lossless WAV.
Yes — no account, no watermark, 10 recordings a day. Adobe Podcast, Krisp and Cleanvoice all limit free usage to push you toward a paid tier. Here the free version cleans recordings up to 45 minutes, ten a day, with no watermark; the optional pass only raises that ceiling, it never lowers it. The ads around the tool cover running our hardware.
No. Your upload is deleted the moment it's processed and the cleaned file is wiped from the server within 45 minutes. Nothing is stored, shared or used to train anything — see privacy.
Zoom recording locations default to a Documents/Zoom folder on your computer. If you search zoom recordings location expecting something else, check there first — hosts can occasionally choose a different folder. Teams recordings location is different: Microsoft saves to Downloads or OneDrive depending on how the call was recorded. Drop the file into the box above to clean it up.
