How to Convert AMF to STL — Quick & Free
Fast, instant AMF to STL conversion. No signup required. Just drop your .amf file and get .stl in seconds.
Batch Settings
Some metadata may not survive
Your AMF file may contain AMF metadata metadata. STL has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
您是否正为3D打印文件格式转换而烦恼？AMF（增材制造文件）以其丰富的色彩和材质信息在某些设计软件中备受青睐，但在实际应用中，尤其是与许多主流切片软件和旧版系统兼容时，STL（标准 Tessellation 语言）文件格式的普及性和稳定性仍是不可替代的。将AMF转换为STL，能有效避免兼容性问题，确保您的3D模型在不同平台间顺畅流转，无论是进行快速原型制作、小批量生产，还是在教育领域分享设计理念，都能大大提升工作效率。我们深知在3D设计和打印流程中，文件转换的便捷与准确性至关重要。本工具旨在为您提供一个简单、高效的解决方案，让您轻松完成AMF到STL的转换，专注于您的创意实现。
- 3D打印模型兼容性优化
- 游戏角色或道具快速导入
- 教育领域3D模型分享
在大中华区，由于部分老旧3D打印设备和普及型切片软件对AMF支持不佳，将AMF转换为STL能更好地满足普惠性应用需求，尤其是在创客教育和小型工作室中更为常见。
About AMF to STL Conversion
Short answer: yes, you can convert AMF to STL online for free, and quality is well preserved with the right settings. Just upload your .amf file to CocoConvert, pick STL as the output, and click Convert. The whole process takes seconds.
Now for the details. AMF (Additive Manufacturing Format) is an XML-based 3D printing format supporting materials and colour. STL stores 3D surface geometry as triangulated meshes — the standard for 3D printing. Converting between these two formats lets you improve file compatibility across devices.
Full Name: AMF uses Additive Manufacturing Format, while STL uses Stereolithography. Compression: AMF uses None (uncompressed), while STL uses None (uncompressed). Typical File Size: AMF uses 1–50 MB, while STL uses 1–100 MB.
Your AMF file is decoded and re-encoded as STL. Converting AMF to STL maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.

Frequently Asked Questions
Is AMF to STL conversion free?
Yes. CocoConvert offers free AMF to STL conversion with generous daily limits — 25 minutes of processing time and up to 5 files per hour (250 MB each). Pro plans remove these limits.
How fast is AMF to STL conversion?
Most files convert in 2–10 seconds depending on size. Large 3d model files may take 30 seconds. Batch jobs process in parallel for maximum speed.
What happens to my files after conversion?
Your uploaded AMF file and the converted STL file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting AMF to STL lose quality?
Converting AMF to STL maintains high quality with CocoConvert's optimised encoder settings.
Can I convert STL back to AMF?
Yes, CocoConvert supports STL to AMF conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
