Convert BMP to SVG
BMP is uncompressed, so there are no compression artefacts to trace around — what the scanner or the CAD export wrote is exactly what the tracer reads.

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 | BMP · 输入 | SVG · 输出 |
|---|---|---|
| 类型 | Raster. Usually uncompressed, so the files are large. | Vector. Paths described in XML. |
| 缩放特性 | Blurs or pixelates past its native size. | Sharp at any size. |
| 颜色 | 1, 4, 8, 24 or 32 bits per pixel. Alpha only at 32-bit. | One solid fill per path, in a palette you can edit by hand. |
| 可编辑于 | Photoshop, GIMP, Paint. | Illustrator, Inkscape, Figma, Affinity Designer, a text editor. |
| 典型用途 | Windows tooling, scanner output, older CAD and CNC exports. | Web, icons, print artwork, the input to a cutter workflow. |
值得了解
BMP files come out of scanners, Windows tooling and older CAD and CNC software, and they are usually the cleanest input a tracer can get: no block artefacts, no ringing, no palette dithering unless the file is 8-bit indexed.
A 1-bit BMP is already black and white, which is what the line-art preset expects — it is the default on this page for that reason. Speckle filtering still matters for a scan, because scanner noise is a scatter of single dark pixels and every one of them would otherwise become a path.
BMP has no alpha except in the rarely used 32-bit form, so expect a background region and delete it after export.
工作原理
Drop the BMP
Drop the .bmp file. 1-bit, 8-bit and 24-bit BMPs are all decoded by the browser.
Stay on line art for a scan
Line art traces one ink colour against paper. Raise the speckle filter until scanner noise stops producing paths.
Export the SVG
The outlines open in Inkscape or Illustrator, and in LibreCAD once the DXF exporter lands.

常见问题
- 01Why is BMP a good format to vectorise?
- Because it is uncompressed. JPEG and lossy WebP both invent detail near edges that a tracer then faithfully reproduces; a BMP has none of that, so the only noise is whatever the scanner or the source software actually produced.
- 02My scan traces as thousands of specks. What do I change?
- Raise the speckle filter until the isolated dark pixels stop becoming regions, and keep line art selected so the trace is binary rather than trying to model paper tone as colours.
- 03Can I edit the SVG afterwards?
- Yes. The output is ordinary SVG — one path per colour region, with a plain fill — so Illustrator, Inkscape, Figma, Affinity Designer and a text editor all open it and all let you move a node.
