Thumbnail Lab

Drop in 2-3 thumbnails and see them exactly as viewers do — desktop sidebar, home grid, mobile, and search — side by side with your title, so you stop guessing. All local. Who it's for: YouTubers and video creators deciding which thumbnail wins. What you get: a self-contained product that works offline — no login, no subscription, and your data never leaves your device. Yours forever, on any device with a browser. Why Toolbench: honest, private, and built to last. Buy once and own it — no accounts, no tracking, no monthly fees. License: single-user, for your own personal and commercial work; don't resell or redistribute the file. Refund: no questions within 30 days.
