How to Resize Videos for Facebook Reels
Answer: Upload your video in SendShort and the AI automatically crops it for the Facebook Reels format (9:16). You can choose each key frame.

- Create a SendShort.ai account
- Upload your video
- Choose the key frame (or leave as is)
- Export & Upload to Facebook Reels
You can either import videos by URL or by file-upload.
Regardless, both methods will take you where you want to be: in a smart video editor that resized your videos for Facebook reels.
