EDITABLE TEMPLATE

HOW TO USE IT

Start with the image you already have.

Choose a local background, write the promise of the video, then drag the headline until the composition reads at a glance. Export PNG when the canvas feels ready. Already have an image to resize first? Use the YouTube thumbnail resizer before adding a headline. The official dimensions shown here come from the site’s YouTube Help source note.

QUESTIONS

Thumbnail maker FAQ

Does the image leave my device?

No. The image is read into a local browser canvas. This page does not upload it or send it to an image API.

What does the canvas target?

The canvas uses the official site guidance shown above: 3840 × 2160 pixels, a 16:9 shape, and a minimum width of 640 pixels.

How does this YouTube thumbnail generator use the editable template?

It is the SVG starter above: a 1280 × 720 canvas with replaceable text, guides, and accent layers. Open it in a design editor, or use it as a visual starting point before rebuilding the idea in this local maker.

Can I move the headline precisely?

Yes. Drag directly on the canvas or use the two position sliders. The current headline, color, and size are redrawn locally.

Does export add a watermark?

No. The PNG is drawn from the canvas and does not add a Thumbnail Tester mark.
