3Dモデルの作業において、異なるソフトウェア間でのデータ交換は避けて通れない道です。特に、古くから親しまれている3DS形式は、多くの3Dモデリングソフトウェアで利用されてきましたが、より汎用性の高いOBJ形式への変換を求める声が少なくありません。OBJ形式は、そのシンプルさと互換性の高さから、現代の多様な3Dコンテンツ制作において標準的なフォーマットとして広く認識されています。この変換ツールは、お客様の貴重な3D資産を、より多くの環境で活用できるよう、スムーズかつ正確に橋渡しすることを目指しています。複雑な設定は不要、直感的な操作で、お手持ちの3DSファイルをOBJ形式へと生まれ変わらせます。さあ、新たな創造の扉を開きましょう。
- アニメ・ゲームのアセット連携
- 建築パースのデータ互換
- フィギュア原型データ作成
日本のアニメやゲーム業界では、歴史的経緯から3DS形式で作成されたモデルデータがまだ多く存在します。これらを最新の制作環境で活用する際、OBJ形式への変換は非常に重要な工程となります。特に、テクスチャやマテリアルの情報が正確に引き継がれるかどうかが、その後の作業効率を大きく左右します。
About 3DS to OBJ Conversion
Dealing with a 3DS file that won't open on your device? You're not alone — 3DS compatibility issues are one of the most common reasons people search for a file converter. 3DS is the legacy 3D Studio format widely used in game development and architecture.
The fix is simple: convert your 3DS to OBJ. OBJ is a simple 3D geometry format supporting vertices, faces, and texture coordinates. This conversion lets you improve file compatibility across devices, solving the problem in seconds rather than hours of troubleshooting.
Full Name: 3DS uses 3D Studio, while OBJ uses Wavefront OBJ. Compression: 3DS uses None (uncompressed), while OBJ uses None (uncompressed). Typical File Size: 3DS uses 1–50 MB, while OBJ uses 1–500 MB (text-based, large for complex models). Converting 3DS to OBJ maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert processes your 3DS file on secure servers in Germany — upload, convert, download. Your files are encrypted via TLS and automatically deleted within 24 hours. No account needed, no software to install, and it works on any device with a browser.
This conversion is ideal when you Your 3DS file won't open on a recipient's device or in an application, or when you A website, service, or platform only accepts OBJ uploads.
The conversion engine behind CocoConvert uses FFmpeg, Sharp, and qpdf — the same open-source libraries trusted by Netflix, YouTube, and enterprise platforms. Pro users can batch convert up to 100 files at once.

Once done, download your .obj file. For batch jobs, download all at once as a zip.
What Happens When You Convert 3DS to OBJ
Your 3DS file is decoded and re-encoded as OBJ.
Your 3DS file is uploaded and the format is validated
The file content is decoded into its raw representation
The data is re-encoded in OBJ format with optimal settings
The converted file is ready for download

Frequently Asked Questions
Why won't my 3DS file open?
3DS files may not open if your device lacks the right codec or application. Converting to OBJ — a more widely supported format — usually resolves this. OBJ is a simple 3D geometry format supporting vertices, faces, and texture coordinates.
Is it safe to convert 3DS to OBJ online?
Yes. CocoConvert encrypts your file via TLS, processes it on isolated servers in Germany, and permanently deletes it within 24 hours. Your files are never shared or analysed.
Will I lose quality converting 3DS to OBJ?
Converting 3DS to OBJ maintains high quality with CocoConvert's optimised encoder settings. CocoConvert uses high-quality encoder defaults to preserve as much fidelity as possible.
How large can my 3DS file be?
Free users can convert files up to 250 MB each. Pro users get a 5 GB limit per file, and Business API users have custom limits.
Can I convert 3DS to OBJ on my phone?
Absolutely. CocoConvert works in any modern browser — iOS Safari, Android Chrome, and all desktop browsers. No app required.
