3Dモデリングの世界では、様々なファイル形式が行き交い、それぞれが異なる特性と用途を持っています。特に、汎用性の高いOBJ形式で作成されたデータを、Autodesk 3ds Maxなどで広く利用される3DS形式へ変換するニーズは少なくありません。OBJはシンプルな構造で多くのソフトウェアに対応していますが、テクスチャやアニメーションの情報保持においては、専用の3DS形式が強みを発揮する場面があります。この変換は、単にファイル形式を変えるだけでなく、お手持ちの3Dアセットをより多様な環境で活かすための大切な一歩となるでしょう。お客様の創造性を最大限に引き出すため、スムーズかつ正確な変換プロセスをご提供いたします。

日本国内で3DS形式を扱う際、特に古いバージョンのソフトウェアや、特定のレンダリングエンジンを使用する場合、マテリアルやUV座標の互換性で調整が必要になることがあります。変換後のデータは必ず一度ご確認いただくことをお勧めします。
About OBJ to 3DS Conversion
Short answer: yes, you can convert OBJ to 3DS online for free, and quality is well preserved with the right settings. Just upload your .obj file to CocoConvert, pick 3DS as the output, and click Convert. The whole process takes seconds.
Now for the details. OBJ is a simple 3D geometry format supporting vertices, faces, and texture coordinates. 3DS is the legacy 3D Studio format widely used in game development and architecture. Converting between these two formats lets you convert between formats quickly.
Full Name: OBJ uses Wavefront OBJ, while 3DS uses 3D Studio. Compression: OBJ uses None (uncompressed), while 3DS uses None (uncompressed). Typical File Size: OBJ uses 1–500 MB (text-based, large for complex models), while 3DS uses 1–50 MB.
Your OBJ file is decoded and re-encoded as 3DS. Converting OBJ to 3DS 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 OBJ to 3DS conversion free?
Yes. CocoConvert offers free OBJ to 3DS 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 OBJ to 3DS 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 OBJ file and the converted 3DS file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting OBJ to 3DS lose quality?
Converting OBJ to 3DS maintains high quality with CocoConvert's optimised encoder settings.
Can I convert 3DS back to OBJ?
Yes, CocoConvert supports 3DS to OBJ conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
