What is Video Clip Converter and Why Use It?
This turns the opening seconds of a video into a short WebM clip, entirely inside the browser: your file is played in the page while its frames are drawn to a canvas and captured with the browser's own MediaRecorder. Nothing is uploaded, which is the practical reason to use it for footage you would rather not hand to a web service. Upload an MP4, WebM or MOV, set a clip length and frame rate, and download the result. Several constraints follow from how the capture works and are worth knowing before you start. Recording always begins at the start of the video, as there is no way yet to choose a different start point. The clip is silent, since audio is not captured, and it is scaled to a maximum width of 480 pixels. Capture runs in real time with the tab in the foreground, so a five-second clip takes five seconds.

Upload or drop your video file (MP4, WebM, MOV) from your device.

Formula / Calculations Explained
Client-Side Video Demuxing and Canvas Encoding
Trims video start and end markers in client memory using HTML5 video and MediaRecorder APIs, encoding lightweight WebM video clips locally.
Important Considerations
- Recording starts from the beginning of the video. There is no way to choose a different start point yet.
- The output is a WebM video file, not a GIF. WebM plays in modern browsers and most players, but some older software and a few chat platforms will not accept it.
- Audio is not included — the exported clip is always silent.
- The clip is scaled to a maximum width of 480 pixels.
- Capture happens in real time, so a five-second clip takes five seconds to record. Keep the tab in the foreground while it runs.
Frequently Asked Questions
Are my personal video clips uploaded to a remote server?▼
No! Video decoding and trimming execute 100% client-side in your web browser using native media APIs. Your files never leave your device.
Why does it export as WebM format?▼
WebM provides high compression efficiency and open web compatibility, making trimmed clips lightweight for web and Discord sharing.
Is there a file size or duration limit?▼
Short clips under a few minutes work best. Processing is bounded by your computer's browser memory since no server is used.
