a high-contrast thumbnail-style image with the controller as the main subject and a clean area for text

Cooking video preview

Input

a steaming bowl of ramen with chopsticks lifting noodles, warm kitchen lighting, shallow depth of field

Expected output

an appetizing close-up food scene with strong color and a clear focal point for a video preview

Podcast episode card

two studio microphones facing each other on a dark desk with a soft gradient background and warm rim light

Expected output

a moody podcast-style image with clear separation between subjects and background

Create a custom thumbnail image for a video, channel, or post from a written description.

Start from a plain description

Type what the thumbnail should show instead of starting from a blank design, then review what the generator returns.

Keep a consistent look

Repeat the same style cues across prompts so covers for a channel or series stay visually connected.

Move from idea to image quickly

A short prompt and a couple of settings are enough to produce a starting cover you can refine.

How It Works

1

Describe the scene

Describe the desired image.

2

Pick the settings

Choose the available generation settings.

3

Generate and review

Generate, review, and download a suitable result.

Writing a thumbnail prompt

A clear description helps the generator produce a cover that reads well at small sizes.

Input Constraints

  • Name the main subject first, then the setting and mood
  • Keep the prompt to a few concrete details instead of a long list
  • Mention the format you need, like a wide cover or a square card
  • Avoid personal or sensitive details in the prompt

Practical Tips

  • Lead with the subject and a strong focal point
  • Add lighting and color cues to set the mood
  • Generate a few options and keep the one that reads best at small size
  • Adjust only one detail at a time when you regenerate

Privacy

  • Do not upload personal or sensitive material unless you have permission to use it.

Usage Rights

  • Confirm that you have the rights needed for the inputs and intended use of the result.
