Resize Video

Media & Video Studio

Scale a video to a new resolution or preset aspect ratio.

What is Resize Video?

Resize Video scales your footage to a new resolution, right in your browser. Pick a common preset like 1080p, 720p, or 480p, or type exact width and height values, then export an MP4 at the new size. The re-encode runs locally with in-browser FFmpeg (WebAssembly), so your video is never uploaded.

How to use Resize Video

  1. Add your video

    Drag a file onto the drop zone or click to browse. MP4, MOV, and WebM work best. A preview appears and the in-browser engine starts loading automatically.

  2. Choose a preset or enter dimensions

    Pick 1080p, 720p, or 480p from the Preset dropdown to fill in standard sizes, or leave it on Custom and type your own Width and Height in pixels. The fields start at the video's native resolution.

  3. Resize and export

    Click Resize video to scale the picture and re-encode it to MP4 (H.264). Dimensions are rounded to even pixels, which H.264 requires.

  4. Preview and download

    Watch the resized result in the built-in player, then click Download to save it. Everything is processed on your device.
