Thumbnails that read
at phone size.
Pick a layout, type two to five big words, drop in your photo and Thumbnail Lab builds a 1280×720 thumbnail. It checks the things that quietly kill clicks: text too small to read in the phone sidebar, weak contrast, words hiding under the video-length badge, and image text that just repeats your title. Make three variants side by side, export PNGs and keep testing. No accounts, no uploads, no tracking. Your images never leave this device.
Readability
A/B/C variants
Same words, different layouts and colours. Upload two or three to YouTube's thumbnail test, or swap them a few days apart, and keep the winner.
