About 图像转 SVG
Last updated: June 2026
OptiPix Image to SVG 可将栅格图像（PNG、JPG、WebP）矢量化为可缩放的 SVG 路径，使用完全在浏览器中运行的 Potrace 风格追踪器。该流程通过可调节阈值（或通过 Otsu 方法自动检测）二值化输入，然后将轮廓追踪为贝塞尔曲线路径。对于彩色图像，该工具会将图像量化为 N 种颜色（2/4/8/16/32），并单独追踪每个颜色层，生成类似 Adobe Illustrator 的图像追踪的多色 SVG。细节级别控件可让您调整路径平滑度、最小特征尺寸和拐角阈值。追踪模式包括：轮廓（单色轮廓）、详细黑白（高细节线条）、彩色（多层）和线条艺术（仅边缘）。输出查看器显示原始栅格图像和矢量 SVG，您可以放大查看栅格图像像素化而矢量图像保持清晰。可另存为 SVG 文件、复制 SVG XML 到剪贴板，或以任意分辨率将 SVG 渲染回 PNG。非常适合将徽标、图标、草图和剪贴画转换为清晰的矢量图，用于打印、Cricut、激光切割或设计工作。
How It Works
图像通过阈值（手动或 Otsu 自动）进行二值化，然后使用 Potrace 风格的追踪器跟随像素轮廓并将其转换为平滑的贝塞尔曲线路径。多色模式通过 K-means 量化为 N 种颜色，并单独追踪每个颜色层，合成为单个 SVG。
Use Cases
- •将 PNG 徽标转换为网站的干净 SVG
- •将手绘草图矢量化为数字艺术
- •追踪剪贴画以供 Cricut 切割
- •将图标转换为 UI 组件库的 SVG
- •准备黑白图像以进行激光雕刻
