Some metadata may not survive

Your FBX file may contain FBX properties metadata. 3MF has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.

FBXから3MFへの変換は、3Dモデルの可能性を広げる大切な一歩です。特に、アニメやゲーム制作、建築設計といった分野で、より効率的かつ高精度なデータ連携が求められる現代において、この変換は非常に重要な意味を持ちます。FBXは多機能なフォーマットである一方、3MFは3Dプリンティングに特化し、色やマテリアル情報も保持できるため、最終的な出力品質を格段に向上させることができます。複雑なモデルも正確に、そして意図した通りの表現で出力するためには、適切なフォーマット変換が不可欠です。当サイトでは、お客様の大切なデータを安全かつ迅速に、最適な3MF形式へと変換するお手伝いをいたします。どうぞご安心の上、ご利用ください。

  • アニメキャラクターの3Dプリント
  • 精密な工業製品試作
  • 建築パースの立体出力

日本の製造業やクリエイティブ産業では、3Dプリンタの活用が急速に進んでおり、FBXと3MF間の正確なデータ変換は、製品の品質や表現力を左右する重要な要素となっています。

About FBX to 3MF Conversion

Short answer: yes, you can convert FBX to 3MF online for free, and quality is well preserved with the right settings. Just upload your .fbx file to CocoConvert, pick 3MF as the output, and click Convert. The whole process takes seconds.

Now for the details. FBX is Autodesk's 3D interchange format supporting animation, materials, and skeletal data. 3MF (3D Manufacturing Format) is an open standard designed for 3D printing workflows. Converting between these two formats lets you convert between formats quickly.

Full Name: FBX uses Autodesk FBX, while 3MF uses 3D Manufacturing Format. Compression: FBX uses Lossless, while 3MF uses Lossless. Typical File Size: FBX uses 1–500 MB, while 3MF uses 1–50 MB.

Your FBX file is decoded and re-encoded as 3MF. Converting FBX to 3MF 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 FBX to 3MF conversion free?

Yes. CocoConvert offers free FBX to 3MF 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 FBX to 3MF 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 FBX file and the converted 3MF file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.

Does converting FBX to 3MF lose quality?

Converting FBX to 3MF maintains high quality with CocoConvert's optimised encoder settings.

Can I convert 3MF back to FBX?
