Show HN: VidStudio, a browser-based video editor that doesn't upload your files | Hacker News

VidStudio is a privacy-focused video editor that runs entirely in the browser, with no accounts or file uploads.

It keeps editing, processing, and export on the user’s device using local storage and client-side processing.

The tool uses browser tech like WebCodecs, FFmpeg WebAssembly, Web Workers, and WebGL for responsive editing.

By avoiding cloud uploads while still supporting MP4 export, it highlights a modern on-device approach to video editing.
