How to use Thumbnail Preview & Compare
- Add two to four thumbnail images and give each variant a title. Inspect the 16:9 crop and keep important text away from edges.
- Switch between compact mobile and wider desktop feed contexts. Compare the combination of image, title, contrast and subject size at the actual preview scale.
- Export the comparison to discuss or review your variants. These are simulated feeds; the tool does not connect to your channel or predict click-through rates.
What are the limits of Thumbnail Preview & Compare?
Compare 2–4 manually supplied images and titles. Feed previews are simulations, not platform screenshots or CTR predictions. Images are cropped to 16:9 in previews.
