Video Resizer
Resize a video to a standard quality such as 1080p or 720p, to a percentage of its size, or to an exact width and height. The picture keeps its shape: an exact size of another shape fits it inside with black bars instead of stretching it.

About
Resize a video online, free. Change its resolution to 4K, 1440p, 1080p, 720p, 480p or 360p, to a percentage of its size, or to an exact width and height. It runs in your browser, so the video is not uploaded.
The quality presets set the short side of the picture, so 720p is 1280 × 720 for a landscape video and 720 × 1280 for a vertical one. With Pixels, Keep the shape makes the height follow the width; turn it off for an exact size of another shape, and the picture fits inside it with black bars instead of being stretched.
Making a video smaller also makes the file smaller. Making it bigger does not add detail. To reduce the file size while keeping the resolution, use the video compressor; to change the shape for TikTok or Reels, use the aspect ratio converter.
