How to make a YouTube thumbnail
Add a background image, then layer on text, shapes, arrows and emojis — drag each element exactly where you want it. Tune brightness and contrast so your subject pops, pick a template to start fast, and export a 1280×720 PNG, the size YouTube recommends. It's free, needs no account, and your image never leaves your browser.
Why thumbnails matter
Your thumbnail is the first thing viewers see in search, suggested videos, and on your channel. Bold, readable thumbnails with a clear focal point measurably increase click-through rate, which in turn helps YouTube recommend your video to more people.
