Resize Video for Landscape, Portrait and Square Dimensions

Nujiz Resize Video re-exports a clip at dimensions suitable for a different screen or platform. Available presets include Full HD 1920×1080, HD 1280×720, square 1080×1080, vertical 1080×1920 and 854×480. You can also choose how the source video fits inside the new frame.

Contain versus Cover

Contain keeps the entire source visible inside the new dimensions and may leave space around it when aspect ratios differ. Cover fills the complete frame but can crop content near the edges. Check faces, captions and logos before choosing the final fit mode.

Choose dimensions for the destination

Landscape dimensions suit conventional widescreen video, vertical dimensions are useful for phone-oriented layouts and square output fits designs requiring equal width and height. Enlarging a low-resolution source does not create detail that was not present originally.

Browser-based re-export

The video is redrawn and processed in the browser, then exported as a new MP4 file. Review the result to confirm that framing, cropping and aspect ratio work for the intended destination.
