Thumbnail Maker

Six sizes built in: YouTube thumbnail, Shorts and TikTok, square and portrait posts, podcast cover and link preview card. Pick one and the canvas changes.

Drop in a photograph and choose whether it fills the frame or sits as a cut-out down one side, with sliders for size and position and a dimmer so your text stays readable over it.

The text is the part most thumbnail tools get wrong. This one gives you a proper thick outline, a second smaller line that can sit in a coloured pill, and the ability to pick out a single word in a different colour - which is the trick behind most thumbnails that work.

Underneath the canvas sit two small previews: your thumbnail at 210 pixels wide, which is the size of a YouTube sidebar, and at 120, which is roughly a phone. This is the feature the whole tool is built around. A thumbnail is designed full size and seen tiny, and the only honest way to know whether yours works is to look at it small while you make it.

Saves as a PNG at full resolution. Nothing is uploaded and there is no watermark.

Comes with a three-page setup guide: how many words survive at thumbnail size, what the outline is for, and the mistakes that only show up once the video is published.
