Remove silences from your videos, automatically
CutNoodle listens to a recording, finds the dead air between sentences, and cuts it out. The whole thing happens in the tab you already have open: there is nothing to install, and the video stays on your computer from first frame to final export.
Open the editor whenever you want to try it on a file of your own.
How it works
Choose a file
Drop in a recording or pick it from disk. The browser reads it in place, so even a large file is ready immediately: there is no upload to sit through.
Let it find the silence
The audio is scanned for passages under your loudness threshold and longer than your minimum pause. Both are yours to set, along with the margin left around each phrase.
Check, then export
Every proposed cut lands on a timeline you can trim, split, merge, or undo. When it looks right, export an MP4 straight to your downloads folder.
Why it runs on your side
Privacy is structural
An unreleased course, a client interview, a recording under NDA: none of it is sent anywhere, because there is no anywhere to send it to. Read the privacy policy if you want the long version.
The file never moves
Web tools that cut silence usually ask for your file first. On a multi-gigabyte recording the upload alone can outlast the edit, and free tiers cap how much you may send. Here the file stays where it is.
Nothing to sign up for
There is nothing to register and no minutes to spend, and exports carry no watermark. The limit is what your own machine can hold in memory, which on a normal laptop is a long recording rather than a short one.
What you need
A recent browser, and that is the whole list. CutNoodle uses ffmpeg compiled to WebAssembly, so the same encoder that desktop editors rely on runs inside the page. There is no Python to set up, no ffmpeg to put on your PATH, and no terminal to open. Chrome, Edge, Firefox, and Safari all work; on desktop, the multi-threaded encoder makes exports noticeably faster than on a phone.
Questions people ask
Is my video uploaded anywhere when I use CutNoodle?
No. CutNoodle opens the file locally in the browser, analyses it locally and encodes it locally. There is no server that receives your media, so there is nothing to store, read or leak.
Do I need to install anything to use CutNoodle?
No. CutNoodle is a web page. There is no download, no setup, no command line, and no account. Open the site and pick a file.
Which video formats and file sizes can CutNoodle open?
MP4, MOV, WebM and MKV files up to 2 GB, as long as the browser can decode the video inside. Exports are written as MP4 with H.264 video and AAC audio, which every editor and platform accepts. Above about 400 MB the export can run out of browser memory, because the file is held in RAM while it is encoded.
How long does a CutNoodle export take?
It depends on the length and resolution of the video and on how fast your computer is, because the encoding runs on your machine. There is no upload wait and no queue, so short clips finish quickly while a long 4K file takes real work.
Can I correct the cuts CutNoodle makes automatically?
Yes. In CutNoodle, silence detection is a starting point, not a verdict. Every clip on the timeline can be trimmed frame by frame, split, merged, reordered, or deleted, and undo is always available.
Is CutNoodle free?
Yes, and there is no account to create. Because nothing runs on CutNoodle's servers, using it costs nothing per video, and exports carry no watermark.
