About this tool

What it does

Crop a region of a video, reframe it to a new aspect ratio (16:9, 9:16, 1:1 and more) with a blurred or colored background, trim the length, add a PNG overlay — and export the result as an MP4.

Why use it

Everything happens locally in your browser. Your video is never uploaded anywhere, so it's completely private and works without an account, install, or watermark — and it's free.

Requirements

A recent version of a modern browser — Chrome, Edge, Safari, or Firefox. The tool relies on new built-in video processing APIs (WebCodecs), so older browsers won't work.
