ShotFormatter
Web · web · tools
I kept uploading a clip to some website just to crop it, and watching the file leave my machine.

ShotFormatter is the opposite: a page in the browser, ffmpeg-in-WASM energy, nothing uploaded. Pick a file, apply the effect, download the result. The file stays in the tab.
const file = input.files[0]
const buffer = await file.arrayBuffer()
const blob = new Blob([output], { type: "video/mp4" })
The catch is the tab. Big files, Safari, memory — ffmpeg-in-the-browser has edges. That’s the trade for never sending the video anywhere. Live at shotformatter.com.
