Why Cropus
Vertical video that still looks directed
Follows the action
A center crop cuts off anyone who moves. Smart crop pans with your subject, smoothly, from the first frame to the last.
Clean jumps on cuts
When the shot changes, the frame jumps straight to the new subject instead of sliding across the cut.
Keep more of the scene
Choose Balanced for a wider view with soft blurred bars, or Fit to show the whole original frame.
Ready to post
You get an MP4 up to 1080×1920 with the original sound, ready for any vertical feed.
Center crop vs Smart crop
The crop that keeps up
A plain center crop cuts whatever happens to be in the middle. Smart crop tracks the subject through the shot, so the action never leaves the screen.
Smooth camera
The crop glides with your subject. No jitter, no seasick jumps between frames.
Cuts handled
On a scene cut the frame jumps cleanly to the new shot instead of panning across it.
Blur fill
Balanced and Fit fill the bars with a soft, blurred copy of your video — or classic black.
Every format at once
Pick every aspect ratio together. One analysis powers them all, so extra formats are quick and free.

FAQ
Frequently asked questions
How do I convert a horizontal video to vertical?
Drop your landscape video into the form above, keep 9:16 selected and press the button. Cropus finds the subject, plans a smooth crop and renders a vertical MP4 for you to download.
Will the vertical version cut people out of the frame?
That's what smart crop prevents. Instead of taking the middle of the picture, it follows the main subject, so a dancer walking to the edge or a speaker leaning aside stays in shot.
What if two people share a wide shot?
Smart crop follows one main subject at a time. To keep both people visible, choose Balanced or Fit: they keep more of the width and fill the rest with a blurred copy of the video.
Does converting to vertical lower the quality?
A vertical crop uses part of the landscape picture, so 1080p or 4K sources give the sharpest result. Cropus exports up to 1080×1920, depending on your source.
Can I get other sizes from the same upload?
Yes. Add 4:5, 1:1 or 16:9 before you start, or later from the video page. Extra formats of the same video don't use any more minutes.
Is there a length limit for the video?
Each video can run up to 60 minutes (120 on Pro), in files up to 4 GB.
