Thumbnail Maker
Upload a background image and add a title and subtitle overlay to create a thumbnail. Control the text position, font size, text color, and background overlay opacity to get the exact look you want. The output is a 1280x720 pixel image — the standard YouTube thumbnail size.
The canvas-based editor shows a live preview as you adjust settings, so you can iterate quickly without repeatedly downloading and checking. The background image is cover-fitted to fill the frame, a semi-transparent overlay darkens it for text readability, and the text is rendered with a subtle shadow.
Useful for creating quick thumbnails for YouTube, blog posts, or social media when you do not need a full design tool. Everything runs in your browser.

Frequently asked questions
What size is the output?▼
1280x720 pixels in 16:9 aspect ratio — the recommended size for YouTube thumbnails. This also works well for blog post headers and social media link previews.
Can I use my own fonts?▼
The tool uses your browser's default sans-serif font for text rendering. Custom font selection is not available — this is a quick thumbnail maker, not a full design editor.
Is my image uploaded to a server?▼
No. The image is loaded and rendered entirely in your browser using the Canvas API. Nothing is uploaded.
