Convert JPG to DXF
A JPG is the worst input a cutter can get and the one you are most often given. Filter the artefacts first, then export DXF outlines a machine can follow.

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 | JPG · 输入 | DXF · 输出 |
|---|---|---|
| 类型 | Raster. A grid of pixels, stored in 8x8 blocks. | Vector. AutoCAD Drawing Interchange — geometry and layers, no fills. |
| 缩放特性 | Blurs past its native size, and the block artefacts scale with it. | Sharp at any size, and it carries real drawing units. |
| 颜色 | Up to 16.7 million colours, no alpha channel. Lossy. | 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 | Photographs, camera output, anything a client emails you. | Laser cutters, CNC routers, plasma tables, vinyl plotters. |
值得了解
JPEG ringing around a hard edge is a band of intermediate pixels a few wide, and the tracer turns each stray band into its own tiny region. Raising the speckle filter drops those regions before they become paths, and lowering the palette merges the block-to-block colour drift back into one fill; between them they are what removes the wobble a cutter would otherwise follow.
If you can get the original PNG, PDF or AI file, use that instead. A JPEG of a logo has already thrown away the information that defines the edge, and no tracer can put it back — it can only make a defensible guess.
DXF has no fills, so what you are producing is a cut path. Decide before exporting whether you are cutting the shape out or engraving it: the first wants the outline, the second wants a centreline your machine software generates.
工作原理
Drop the JPG
Drop the artwork. It is decoded and traced locally.
Filter the artefacts
Laser preset, then raise the speckle filter until the contour stops rippling along the edges.
Export DXF
Check units and interior holes in your machine software before cutting anything expensive.

常见问题
- 01Why does the cut path look wobbly?
- JPEG ringing. The compressor put a band of intermediate pixels along every hard edge, and a threshold-based trace follows that band. Raise the speckle filter, drop the colour count, and if you can, get a lossless copy of the artwork.
- 02Which DXF version is written?
- AutoCAD R2000 (AC1015) — the version cutter, CAM and sign software reads most reliably.
- 03Does the file leave my machine?
- No. The tracer is WebAssembly running in a Web Worker in this tab, so the pixels stay on your machine. There is no upload step, which is also why it keeps working with the network off.
