Try it NowCómo generar miniaturas de YouTube
Crea miniaturas de YouTube con alto CTR en 3 sencillos pasos con el AI Thumbnail Maker de OpenArt.
Sube tu imagen
Start by uploading your base image, whether it’s a product shot, gameplay screenshot, or a portrait. OpenArt.ai supports various image formats to make the process smooth and convenient.
Describe tu miniatura
Enter a detailed description of the thumbnail you want. Include elements like text, background style, lighting, character poses, or specific visual effects. The AI uses your description to generate a professional, attention-grabbing thumbnail.
Editar y descargar
Adjust layouts, text, colors, and composition if needed. Download your high-resolution thumbnail ready for YouTube, Shorts, tutorials, gaming, podcasts, or product reviews.
Qué hace que una miniatura de YouTube consiga clics de verdad
One Clear Focal Subject
The best thumbnails focus on one clear subject. Too many faces or objects confuse viewers. Highlight one person, object, or moment with a clean background to make it instantly understandable.
Faces with Big Expressions
Strong facial expressions like shock, excitement, or surprise immediately attract attention and spark curiosity, making viewers more likely to click, especially on small mobile screens.
Añadir texto de titular
Use short, bold phrases that reinforce the hook rather than explain the full story, drawing attention and sparking curiosity. Examples include: “BIGGEST MISTAKE” or “I LOST $10K,” which immediately communicate stakes and make viewers want to learn more.
Text Has to Read at 168 × 94 Pixels
La mayoría de los espectadores descubre los vídeos en dispositivos móviles, así que el texto debe ser grande, en negrita, con mucho contraste y mínimo. Normalmente debería tener entre 3 y 5 palabras para que se lea al instante.
El alto contraste gana al diseño sutil
Subtle color palettes and soft compositions may look elegant, but they often get lost in YouTube’s crowded feeds. Bright colors, dramatic lighting, and clear subject-background separation capture attention better.
Specificity Creates Curiosity
Specific thumbnails spark more curiosity than vague ones. Details such as “I Tried a $10,000 Sushi Dinner,” dramatic objects, or clear outcomes make the video’s value obvious. The more concrete specific the thumbnail, the higher the click potential.
