Video resizer on iPhone

Shooting videos on an iPhone is incredibly popular. Its built-in camera functionality and the advancements in camera technology over the years have made it a convenient tool for capturing high-quality videos. However, most people shoot vertically, so many wonder how to resize videos on iPhone.

The ability to change the aspect ratio of an iPhone video gives a greater control over how the video is displayed and enhances the overall visual experience for viewers. It also allows optimizing the video for different screen sizes and orientations. For instance, if there is a video shot horizontally that the user wants to share on Instagram Stories (which uses a vertical aspect ratio), changing the iPhone video resolution ensures that it fits the screen.

Our simple tool allows resizing iPhone video fast and easily without downloading any video crop app for iPhone.
