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: nothing to install, nothing uploaded, 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
STEP 1
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.
STEP 2
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.
STEP 3
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.
No upload, no waiting
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 never moves.
No account, no quota
Nothing to register, no minutes to spend, 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?
No. The file is opened locally by the browser, analysed locally, and encoded locally. There is no server that receives your media, so there is nothing for us to store, read, or leak.
Do I need to install anything?
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 formats can I open?
Anything your browser can decode, which in practice covers MP4 and MOV with H.264 video, plus WebM. Exports are written as MP4 with H.264 video and AAC audio, which every editor and platform accepts.
How long does the export take?
It depends on the length and resolution of the clip 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 automatic cuts?
Yes. 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 it free?
Yes, and there is no account to create. Because nothing runs on our servers, using CutNoodle costs us nothing per video.
