# Resizing your video

Auto-resize allows you to easily transform your video into a different size or aspect ratio to post on social media. If your video is in landscape format (16:9), you can change it to square (1:1), portray (4:5) or vertical format (9:16), and vice versa (square (1:1) and portrait (4:5) are only supported by select templates). Just click on **Auto resize** from the video's share page, then select the size you’d like. We’ll create a copy of your video in that size, and start rendering it right away. To view or download the new format, just go to your dashboard!
