**Excerpt:** 酷炫背景生成整合 Trianglify、particles.js、Gradient Topography、Unsplash 四款开源工具，5 秒下载 1920×1080 PNG/SVG 背景图。

酷炫背景生成（coolbackgrounds.io）将 Trianglify、particles.js、Gradient Topography 和 Unsplash 四个开源项目整合在同一页面中。用户无需启动 Photoshop，5 秒即可获得一张 1920×1080 的 PNG 图片。

| 商用许可 | 官网未明示，需自行核实 |
| 注册要求 | 无需账号 |

## 4 个工具分别能干什么

-   **Trianglify**：生成三角形几何拼接图案，由作者 Quinn Rohlf 独立维护。该工具支持调整调色板、单元格大小和噪声参数。本站作者最初用它为 HTML Color Codes 教程制作了主视觉图。
-   **particles.js**：生成粒子分布图，由 Marc Brüderlin 开发并持续更新。可调节的参数包括粒子数量、颜色和连线，用于制作网页 banner 比打开 Illustrator 更快。
-   **Gradient Topography**：生成渐变地形图，由本站作者自创，灵感来源于 Codrops。作者本人的 iPhone 壁纸便使用了该工具的黑色与深灰色配色方案。
-   **Unsplash 图库**：直接调用 Unsplash API，按关键词检索照片并叠加渐变滤镜。这是给客户提案时快速制作主视觉素材的有效方式。

## 三步拿到图

1.  在[酷炫背景生成](https://coolbackgrounds.io/)首页选择一个工具入口，每个工具都对应一个独立的控制面板。
2.  调整颜色、尺寸、密度等参数，右侧区域会实时预览效果，整个过程无需登录。
3.  点击 Download 按钮，图片将以 PNG 或 JPG 格式直接下载到本地。Trianglify 工具还额外支持 SVG 矢量格式输出。

## 几个少有人提的规格细节

该平台未公开 API（应用程序编程接口），因此无法进行程序化批量调用。但其底层的 Trianglify.js 和 particles.js 均为开源项目，开发者可将它们集成到自己的构建流程中。

网站没有离线模式，断网后完全不可用。同时，平台不提供用户账号和历史记录功能，刷新或关闭页面会导致当前配置丢失，建议在调整到一半时截图保存。

输出分辨率锁定为 1920×1080 像素，不可自定义。若需制作手机竖屏壁纸，只能对下载的图片进行后期裁切。

## 客观来说

酷炫背景生成的图像许可条款在官网和 FAQ 中均未明确写明，用于商业用途前，建议用户自行截图存证。模板池规模不大，Trianglify 和 particles.js 在参数调节上存在上限。想要获得更具差异化的效果，可以在 Unsplash 工具中更换关键词组合，或将生成的 PNG 图片导入 Figma 进行二次加工。

如果未来该平台接入 AI 生成器（例如 Stable Diffusion），这些新生成的图像是否会延续当前可免费下载、可商用的状态？开发者对此没有公开承诺。
