About 3D 模型轉換器
在上方上傳 3D 模型，選擇你需要的格式，適用於網頁、AR、3D 列印或 CAD。將 OBJ 或 FBX 轉成精簡的 GLB/GLTF 以用於即時檢視器，匯出 STL 給你的 3D 印表機使用，或是轉換來自 CAD 軟體的 STEP 和 IGES 檔案 —— 完全不需要安裝笨重的應用程式。轉換過程會保留幾何形狀，且不需要註冊帳號。無論你是在打造網頁體驗、準備列印檔案，還是在不同工具之間搬移檔案，以下每個轉換工具都是免費、安全，且能在任何裝置上使用。檔案會以私密方式處理，並在轉換完成後自動刪除。
遊戲與網頁開發者將 GLB/GLTF 當作即時 3D 檢視器與 AR 的標準格式，因為它能把幾何形狀、材質和貼圖打包成單一精簡檔案。要匯出給 3D 印表機使用的創作者需要 STL 或 3MF，而在不同 CAD 軟體之間搬移檔案的工程師則依賴 STEP 和 IGES 這類中立格式，以在不同軟體之間保留精確的幾何資訊。MiConvert 能串接這些工作流程 —— 例如將 Blender 匯出的 OBJ 轉成網站使用的 GLB，或將 SketchUp 模型轉成可供列印的 STL —— 完全不需要安裝原本的建模軟體。
Frequently Asked Questions
要如何轉換 3D 模型？
把模型拖曳到上方的上傳區（或點擊瀏覽），然後選擇目標格式，轉換完成的檔案會自動下載。
3D 轉換是免費的嗎？
是的。所有 3D 轉換工具都免費使用，不需註冊帳號。升級 Pro 版可解鎖更大的檔案與批次轉換功能。
哪種格式最適合網頁或 AR 使用？
GLB 和 GLTF 最適合網頁與 AR 檢視器，而 USDZ 則最適合 Apple AR Quick Look。
我的模型的幾何形狀和貼圖會被保留嗎？
我們會完整保留幾何形狀，貼圖與材質也會在目標格式支援的範圍內一併轉移過去。
我的檔案安全嗎？
是的。檔案會以安全連線傳輸、私密處理，並在轉換完成後自動刪除。
3D 列印需要哪種格式？
STL 是切片軟體與 3D 印表機最普遍接受的格式。如果你的印表機或切片軟體還需要顏色/材質資料，3MF 是 STL 無法支援的功能的現代替代格式。
為什麼 CAD 檔案使用 STEP 或 IGES，而不是 OBJ？
STEP 和 IGES 儲存的是工程上使用的精確、可編輯實體幾何資料，而 OBJ 和 STL 只描述三角化的表面網格。在兩者之間轉換，能讓 CAD 資料進入 3D 列印或視覺化工具，反之亦然。
