About this tool
The aspect ratio is kept: you only pick the height and the width is calculated automatically. The result is saved as MP4.
Everything happens in your browser with WebCodecs: the video is never uploaded, however large it is.
Frequently asked questions
Which browsers does it work in?
Up-to-date Chrome, Edge and other Chromium browsers, and recent Firefox and Safari. If your browser can't create a format, we'll tell you.
Can I increase the resolution?
No: upscaling a video adds no detail, only file size.
