Convert PNG to DXF
Cutter software wants outlines, not pixels. Trace the PNG into closed paths here, then export DXF for LightBurn, LibreCAD, Fusion 360 or your plotter.

为什么选择 vectortrace
- 凭证 1 / 3
浏览器内运行,隐私可靠
该引擎是运行在您设备上一个 Worker 中的 WebAssembly 程序。您的图像绝不会被上传 —— 因此没有可泄露的内容,没有需要删除的内容,也无需盲目信任任何一方。
- 凭证 2 / 3
真正可编辑的路径,而非套壳处理
引擎会先将图像划分为若干色块区域,提取区域之间的边界,并对其进行曲线拟合。得到的是真正的几何图形 —— 每个区域一个填充,每个节点都可以自由移动 —— 全部在标签页本地生成,从不经过服务器。
- 凭证 3 / 3
印刷与生产实际使用的格式
SVG 和 PDF 适用于设计稿;EPS 和 DXF 适用于刻字机、雕刻机与刺绣软件。都是真正可用的文件,能在 Illustrator、Inkscape 和 LibreCAD 中打开 —— 而不是内嵌 JPEG 的 SVG。
格式速览
| 格式速览 | PNG · 输入 | DXF · 输出 |
|---|---|---|
| 类型 | Raster. A grid of pixels. | Vector. AutoCAD Drawing Interchange — geometry and layers, no fills. |
| 缩放特性 | Blurs or pixelates past its native size. | Sharp at any size, and it carries real drawing units. |
| 颜色 | Up to 16.7 million colours with 8-bit alpha. Lossless. | None as a fill. Colour in DXF is a property of the layer. |
| 可编辑于 | Photoshop, GIMP, Affinity Photo. | LibreCAD, AutoCAD, Fusion 360, LightBurn, most cutter software. |
| 典型用途 | Screenshots, web images, marks exported from a design tool. | Laser cutters, CNC routers, plasma tables, vinyl plotters. |
值得了解
DXF describes geometry and layers. It has no fills, no gradients and no alpha — a cutter only needs to know where the tool goes. That is why the laser preset traces binary and fits straight polygon segments rather than splines: a machine controller interpolates arcs its own way, and a polyline says exactly one thing.
DXF also carries drawing units, which SVG does not by default. The size you cut is the size in the file, so decide the physical dimensions before you export rather than scaling in the machine software afterwards.
Interior holes matter. A letter O has to be two closed contours with opposite winding or the cutter fills it in. Cutout mode produces disjoint regions for exactly this reason.
工作原理
Drop the PNG
Drop the mark or drawing you want to cut. It is traced in this tab.
Use the laser preset
Binary trace, polygon fitting, high coordinate precision. Check that interior holes are separate closed contours.
Export DXF
Open the result in LightBurn, LibreCAD or your machine software and confirm the units before you cut.

常见问题
- 01Which DXF version is written?
- The exporter targets AutoCAD R2000 (AC1015), which is the version cutter and CAM software reads most reliably. It is also the version most sign and laser tools list as their recommended import.
- 02Why does my cut have double lines?
- A traced outline is a filled region boundary, so a stroke in the original becomes two contours — one for each side of the line. That is correct for cutting a shape out and wrong for engraving a line; for engraving, cut on a centreline in your machine software.
- 03Can I set the size in millimetres?
- DXF carries units, so the exported drawing has a real size. Set the physical dimensions before export rather than scaling afterwards, which is where rounding creeps in.
