将 PNG 图片拖放到上方的上传区域，或点击浏览文件。我们的转换器支持最大 20MB 的 PNG 文件。
调整可选设置，如细节级别、高度缩放和平滑度。然后点击转换按钮，我们的 AI 引擎将从您的 PNG 图片生成3D STL 模型。
直接在浏览器中预览3D模型并下载 STL 文件。输出文件是水密的，可直接使用任何切片软件进行3D打印。
了解 PNG 到 STL 转换涉及的文件格式，以及为什么这种转换对3D打印很有用。
PNG (Portable Network Graphics) is a lossless image format developed in 1996 as a patent-free alternative to GIF. PNG preserves every pixel exactly as captured, making it ideal for screenshots, digital art, logos, and images requiring transparency. It supports 24-bit RGB color, 32-bit RGBA with alpha transparency, and grayscale modes. PNG files are typically larger than JPG due to lossless compression, but they retain perfect image quality without compression artifacts. The format is universally supported across all web browsers, operating systems, and image editors.
STL (Stereolithography) is a 3D file format that represents the surface geometry of a three-dimensional object using a mesh of triangular facets. Created by 3D Systems in the 1980s, STL is the standard format for 3D printing, CNC machining, and rapid prototyping. Each STL file describes the outer shell of a 3D model without any color, texture, or material data -- it is purely geometric. STL files can be opened in slicer software like Cura, PrusaSlicer, and Bambu Studio to prepare models for 3D printing. The format is universally supported by all 3D printers and manufacturing equipment.
Convert PNG to STL to turn your high-quality images and digital artwork into 3D-printable models. PNG's lossless quality produces cleaner, more detailed STL geometry compared to lossy formats. This is especially useful for converting logos, icons, technical diagrams, and pixel art into 3D objects with crisp edges and precise detail.
我们的 AI 转换器以高精度和高速度将 PNG 图片转换为高质量的可3D打印 STL 模型。
Our advanced AI engine analyzes your image and generates accurate 3D geometry, preserving intricate details and fine surface features in the resulting STL model. The conversion process is fully automated and produces print-ready 3D files.
Every STL file generated from your image is watertight, manifold, and optimized for 3D printing. Import the STL file directly into any slicer software and start printing without additional mesh repair or cleanup.
Convert images to STL entirely in your browser. There is no software to download, no plugins to install, and no account registration required. Our cloud-based tool works on Windows, macOS, Linux, and mobile devices.
Your image files are processed securely and automatically deleted after conversion. We use local browser processing where possible, and all uploaded images are wiped from our servers to ensure complete privacy of your data.
