We build a cinematic slideshow studio. Along the way we wrote a lot of tiny video and photo utilities for ourselves — converters, compressors, trimmers, resizers. They're useful on their own, so we packaged them up as free tools. Every one runs entirely in your browser using FFmpeg compiled to WebAssembly — the same library professional editors use. Your files never leave your device.
The full Studio adds AI scene pacing, music ducking, narration, and 4K export.
