Frequently Asked Questions

Are my video or audio files ever uploaded?

No. LocalVideoKit processes all media files directly in your web browser using HTML5 File APIs, WebCodecs, and WebAssembly. Your files are never sent to any server or cloud service.

Is there a file size limit?

Because files are processed entirely in your browser's memory, the practical limit is your device's available RAM and your browser tab's memory ceiling. Shorter clips and files under a few hundred megabytes process comfortably on most devices; very large or long files may run slowly or fail on lower-memory devices.

How does target size video compression work?

By analyzing the exact duration of your video clip, LocalVideoKit computes the necessary constant bitrate budget (audio + video) to hit your chosen megabyte ceiling. WebCodecs encodes the video in your browser with no quality lost to server recompression.
