Add Text to a Thumbnail

Text is the second half of a thumbnail

An image alone rarely does the job. The thumbnails that get clicked pair one clear picture with two to four words that finish the thought the title started — and they set those words in a way that survives being shrunk to a seventh of the size they were designed at.

This tool does that one job. Drop an image, type the words, and it renders them onto a 1280×720 canvas with the treatments that actually keep text legible in a feed: a heavy weight, a thick outline, an optional drop shadow, and a solid colour block when the background is too noisy for either.

Why the outline matters so much

White text on a photograph is unreadable wherever the photo happens to be light. A dark outline of a few pixels solves it everywhere at once — the letterforms keep their edge over a bright sky and a dark shadow alike, without you having to hunt for a clean patch of background to put them on. The default here is 6px at 1280 wide, which is roughly where it starts reading on a phone. Push it further for busy backgrounds.

Three or four words, no more

In the up-next sidebar your thumbnail is 168 pixels wide. Anything past about four short words becomes a grey smear at that size, and the title next to it is already carrying the detail. Say the thing the title cannot: the number, the twist, the result.

The safe zones

Tick show safe zones to see the two areas to keep clear: a 5% margin all the way round, and the bottom-right corner where YouTube's duration badge sits on every thumbnail in a feed. The guides are drawn over the preview only — they are never part of the file you download.
