YouTube Thumbnail Maker — bold 1280×720, type and it's done
Make a high-click YouTube thumbnail without Photoshop: drop a screenshot or photo as the background, type a big headline, add a highlight block and a small label (TUTORIAL, EPISODE 12…), and Poster Cat lays it out at the exact 1280×720 (16:9). Adjust the overlay so the text stays readable, then download. It all runs locally in your browser — no login, no watermark, nothing uploaded.

Frequently asked questions
What size is a YouTube thumbnail?
1280×720 px, 16:9 — the same ratio as the video. Keep the file under 2MB; the PNG this tool exports is typically within that limit.
Why can't anyone read my thumbnail text on mobile?
Thumbnails shrink a lot in the feed. Use few, large words, turn on the highlight block, and raise the overlay to darken the photo so contrast is high — then it reads even at small sizes.
Is my image uploaded anywhere?
No. The background and text are composited locally in your browser — nothing leaves your device, so unreleased frames stay private.
