Resize a video for any platform, without cutting it
Make one video fit Reels, TikTok, Shorts, square posts or YouTube. Pick the size, choose a blurred background, black bars or fill, and see how it will look before you save.
To resize a video, open it here and pick a size: 1080×1920 for Reels, TikTok and Shorts, 1080×1080 square, 1080×1350 portrait, 1920×1080, 1280×720, 854×480 or a custom width and height. If the shape changes, choose a blurred copy of the video behind it, black bars, or fill (which cuts the edges). The preview shows the result; click Resize and save and the browser records it in real time with the sound, as MP4 where it can and WebM otherwise.
