Pick the backdrop
A bright gradient, or a screenshot from your video, darkened so text stands out.
Free tool
Make a thumbnail people click: a bright background or your own screenshot, a cut-out photo of you with the white outline thumbnails use, and big titles with a thick outline and shadow. Drag everything into place and download a JPG at 3840 x 2160, the size YouTube now recommends, or a small 1280 x 720. No watermark, nothing uploaded.
A photo of yourself with the background removed (a PNG with see-through edges) gets a white outline automatically. Make one with the background remover.
