Ensure maximum printer compatibility by converting AMF files to STL. Bridge the gap between modern additive manufacturing format and legacy slicer software.
Please wait
AMF (Additive Manufacturing File Format) is a modern standard with support for color, materials, and complex geometries. However, many slicers and 3D printers still only accept STL. This converter extracts mesh geometry from AMF files and produces clean STL output compatible with virtually any 3D printing software.
DefaultY-up
Determines the 'up' axis of the exported model. Different 3D software uses different conventions. Selecting the wrong system may cause the model to lie on its side.
Convention used by OpenGL, Three.js, and most Web 3D engines. Choose this for models from web or game engines.
Convention used by Blender (default), 3ds Max, and some CAD software. Try this if the model appears sideways.
Default0°
Range-180° – 180°
Rotate the model around the X axis (degrees). Useful for correcting axis misalignment or print orientation.
Default0°
Range-180° – 180°
Rotate the model around the Y axis (degrees). Useful for correcting axis misalignment or print orientation.
Default0°
Range-180° – 180°
Rotate the model around the Z axis (degrees). Useful for correcting axis misalignment or print orientation.
DefaultBinary STL
Choose the STL storage format. Both formats produce identical print results.
Smaller file, faster to load. Supported by Cura, PrusaSlicer, Chitubox and all major slicers. Recommended for 3D printing.
Plain text format, readable in any text editor for debugging. File size is ~4-6x larger than binary.

STL only stores mesh geometry. AMF-specific features such as per-vertex colors, multiple materials, curved triangles, texture maps, and print configuration metadata are stripped during conversion. Only the triangle mesh is preserved.
Yes. All mesh objects within the AMF file are merged into a single STL file. If you need to print objects separately, consider splitting them before conversion.
AMF supports curved triangle patches for smoother surfaces. During STL conversion, curved triangles are tessellated into flat triangles. The tessellation resolution is automatic and generally produces good results for printing.
The output is binary STL by default, which is more compact and widely supported. You can toggle the format option in conversion settings if you need ASCII STL.
AMF supports color per vertex, multiple materials in one file, curved surfaces, and print metadata. If your slicer supports AMF (e.g., PrusaSlicer, Cura), keeping the AMF format preserves more information. Convert to STL for maximum compatibility with older software.
Yes, Any3D's core features are free to use forever. We provide format conversion, model optimization, and online preview at no cost, with no registration required.
No. Files you select are processed only in your browser on this device—they never leave your device and are never sent to our servers. We don't store any user files; after processing, related data in browser memory is released.
No installation required. Any3D is entirely browser-based—just open the webpage to use all features. It works on Windows, Mac, Linux, and other major operating systems.
The processing capacity depends on your device performance and the model's vertex count and texture complexity, rather than file size alone. We impose no file size limit, but when a model exceeds what your device can handle, the page may lag or even crash.
