# Give the next Bilibili video a thumbnail with a clear hook

Bilibili Thumbnail Maker turns a topic, title, script, key frame, portrait, product photo, or reference image into a Bilibili video thumbnail with one strong focal visual, a readable hierarchy, and room for the headline. It makes one 2K landscape 16:9 PNG, and an existing thumbnail can be refined into a repeatable channel look. Bilibili Thumbnail Maker works in Claude Code, Codex, Cursor, and other agents that run Skills.

## A clear thumbnail direction for every Bilibili upload

### One clear visual hook

Set a strong focal subject and readable hierarchy so the topic is recognizable at thumbnail size.

### Start from what you already have

A topic, title, script, key frame, portrait, product photo, or reference image can all start the cover.

### Grow into a channel look

Refine an accepted cover into one consistent style for explainers, reviews, vlogs, and more.

## How it is made

### Start from the video idea · Decide what viewers should notice first

Shape the title, central subject, and visual contrast into a cover that makes the video topic easy to scan.

- Video hook
- Focal subject
- Room for the title

## For explainers, reviews, vlogs, games, food, and entertainment

### A repeatable creator series

Carry an accepted cover direction into a consistent visual family for explainers, reviews, vlogs, and more.
