Good to know.
- Representative layouts are not exact copies of every YouTube interface.
- The preview does not predict click-through rate or video performance.
- Image, title and channel text stay local. No YouTube API is used.
A little more clarity.
Does this publish my thumbnail?
No. It is a local preview only. Upload the finished thumbnail to your channel yourself.
What aspect ratio works best?
The preview uses a 16:9 frame. Your image is fitted into that frame so you can inspect its composition.
