TikTok, the popular social media platform, has taken the world by storm. From influencers to casual users, everyone is engaged in creating and sharing short video content. However, ensuring your video content is optimized for TikTok’s format is crucial to maximize your reach. This article aims to guide you on how to resize videos to fit TikTok perfectly, the best apps to use, the video size format for TikTok, uploading large videos, and more.

How do I resize a video to fit TikTok?

The video size format for TikTok typically comes in a vertical video aspect ratio of 9:16, similar to an Instagram story. This is in line with the standard dimensions of a smartphone screen, ensuring your content fully utilizes the viewer's screen. Resizing your videos is necessary to maintain this aspect ratio and video quality, creating an immersive experience for your audience.

To resize videos for TikTok on your Mac, iPhone (iOS), or Android device, follow these steps:

  1. Select the video clip: Locate and open the video file you want to edit.
  2. Choose the 'Resize or Crop' option: Most video editing tools feature a resize or crop video option, which allows you to change the video dimensions.
  3. Customize the aspect ratio: Adjust the video aspect ratio to 9:16 to fit TikTok's vertical format.
  4. Save and export: After resizing, click on the export button to save the new version of your video.

Remember to preview the changes before exporting, ensuring your content appears as you expect.
