Click an empty spot to add a point. Drag a point to move it. Double-click a point to delete it. The height of the curve is how strong the glitch is at that moment.

Clip length sec how long the exported MP4 will be

How it works: load a video or image, apply a preset, fine-tune with the knobs, and drag the timeline to scrub through the video. Export an MP4, or use Save Frame (PNG) for a still.
Export runs fully in your browser (WebCodecs). Portrait and landscape are both supported, and a video's original audio is kept.
Works on desktop and mobile. Exporting an MP4 needs a recent browser with WebCodecs — Chrome or Edge on desktop and Android, or Safari on iOS 16.4 and later. Older browsers can still preview but may not export.
