What Thumbnail Studio does
Create click-worthy YouTube thumbnails — bold text, shapes, emoji overlays, 1280×720 export.
How it works
Canvas2D rendering with web-fonts loaded locally; PNG/WebP/GIF/animated-WebP export. The processing code runs inside the page, so your file is not uploaded to a server — you can confirm this in your browser's DevTools → Network tab.
