The Problem with Cloud-Based Video Editors

Most online video editors force you to upload your entire 1GB or 2GB video file to their remote servers before you can even begin cutting. On typical home or mobile internet connections, uploading 2GB takes anywhere from 10 to 30 minutes, followed by another cloud processing queue.

If your upload fails at 90%, you have to start all over again, and your private footage remains stored on an unknown third-party server.

How In-Browser Local Processing Works

VidSplitter processes your video completely inside your device browser using WebAssembly. The video file is read directly from your local storage and sliced in device memory.

Because zero bytes are transmitted across the internet, you can split a 2GB file in just 2 to 3 seconds with zero bandwidth usage and 100% privacy.

Pro Tips
