How to Convert 16:9 Video into Shorts

To resize a 16:9 video into the 9:16 YouTube Shorts format, import your video to SendShort.ai — a free AI which automatically resizes the video for you.

Turn long videos into shorts, or just add captions
This is how SendShort works

Here’s the step-by-step process:

  1. Sign up for free for SendShort.ai
  2. Add your video (paste the URL or upload)
  3. Select the main frame for each part of the video
  4. Save changes & Download
  5. Upload the video to YouTube Shorts

SendShort does way more than resizing your videos. With it, you can also add subtitles automatically, b-rolls, emojis, and so on.
