Thumbnail: The cover image for a YouTube video. One of the most important factors in whether viewers click a video, and it greatly influences CTR (click-through rate).
Aspect Ratio 16:9: The standard aspect ratio for YouTube thumbnails. The recommended resolution is 1280×720 pixels. This tool is optimized for this ratio.
Canvas API: An HTML5 drawing feature built into browsers. This tool uses the Canvas API to perform text decoration, image compositing, and effect processing in real time.
CTR (Click-Through Rate): The ratio of clicks to impressions. A compelling thumbnail can dramatically increase CTR, leading to more video views.
Text Overlay: A text element placed on top of an image. In thumbnails, bold, outlined, or shadowed text is effective for maximum visual impact.
Font Decoration: A collective term for visual effects like typeface, size, color, outline (stroke), and shadow. This tool lets you adjust all of these with a live preview.
Image Export (PNG/JPEG): The format for downloading your finished thumbnail as a file. PNG supports high quality and transparency; JPEG results in smaller file sizes.
