Thumbnail drafts that read on mobile
Creators publishing weekly face a bottleneck: filming is done but the thumbnail still defaults to an auto-frame. This generator helps you iterate bold titles, color blocks, and contrast before uploading to YouTube or Shorts cover art.
Design heuristics
Use complementary colors, one focal face or object, and stroke or shadow on text. Preview at phone width—if you squint and cannot read the headline, simplify.
Tool boundaries
No layer masks, brand kit sync, or A/B testing integration. Export PNG and manage versions manually; advanced creators may still prefer dedicated design suites.
