- 三大核心工具：视频转序列帧、图片压缩、音频压缩
- 响应式布局：包含顶部导航、页脚和侧边栏
- 文件上传：支持拖拽上传，使用 react-dropzone
- 进度追踪：实时显示上传和处理进度
- 可配置工具：每个工具都支持自定义参数配置
- 结果预览：支持下载处理后的文件
- 4K 优化：针对大屏幕优化的响应式设计
- API 路由：文件上传和处理的模拟实现

技术栈：
- Next.js 15 (App Router)
- React 19
- TypeScript (严格模式)
- Tailwind CSS（自定义 4K 断点）
- shadcn/ui 组件库
- Framer Motion 动画
