Shorts only shows vertical video full-screen. Anything else gets shrunk into the middle with a lot of empty space around it.
The crop box arrives at 9:16 already. Drag it so your subject is where the eye lands, then export.
Shorts caps length at the platform level, not here. Trim first if the clip runs long.
FAQ
How long can a Short be?
That is YouTube’s rule, and it changes. Use the trim tool to cut to whatever the current limit is.
Does the resolution matter?
1080×1920 is the sweet spot. Higher just gets re-encoded.
Will it still work if my footage is square?
Yes, it crops the sides. Anything important near the edges should be dragged into frame.
Is the sound kept?
Yes.
Does it add a watermark?
No. Nothing this site exports carries one.
