Crop a Video to Any Aspect Ratio
Reframe any video for Reels, Shorts, TikTok, Instagram or YouTube. Pick 9:16, 1:1, 4:5 or 16:9, then either drag a crop frame to keep the best part, or fit the whole video with a blurred background. The result is a clean MP4 with the audio kept — and it works both ways, so a horizontal video becomes vertical and back again.

Your video is uploaded to our own server only to re-frame it, then the source is deleted as soon as processing finishes. Converted videos are kept for a limited time and never shared.
GOOD TO KNOW
Which ratio for which platform
| Ratio | Best for |
|---|---|
| 9:16 | Instagram Reels, YouTube Shorts, TikTok, stories — full-screen vertical (1080×1920) |
| 4:5 | Instagram & Facebook feed posts — takes the most vertical space in the feed (1080×1350) |
| 1:1 | Square posts and profile grids (1080×1080) |
| 16:9 | YouTube, widescreen players and presentations (1920×1080) |
- Crop keeps the frame full and cuts the edges — drag the frame to choose which part stays. Best when the subject is off to one side.
- Fit keeps the whole video and fills the empty sides with a blurred copy of the video or black bars. Nothing is cut off.
- We never enlarge a small video — if the source is smaller than the target, the output matches the source instead of blowing it up.
