DAE Won't Open? Convert to OBJ Instantly
Fast, instant DAE (COLLADA) to OBJ conversion. No signup required. Just drop your .dae file and get .obj in seconds.
Batch Settings
Some metadata may not survive
Your DAE file may contain Collada asset info metadata. OBJ has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
3Dモデルの作業、お疲れ様です。DAE（Collada）形式は、その汎用性から様々なツールで利用されていますが、多くの3Dアプリケーション、特にゲーム開発や一部のレンダリングソフトウェアでは、よりシンプルで互換性の高いOBJ形式が求められることが少なくありません。DAEからOBJへの変換は、モデリングデータを次のステップへスムーズに進めるための大切な橋渡しとなります。複雑な設定に悩むことなく、大切な作品のディテールを損なうことなく、効率的にフォーマットを移行できるよう、本ページがお手伝いいたします。日本のクリエイターの皆様が、より自由に、そして迅速に作品を形にできるよう、この変換ツールをぜひご活用ください。
- ゲーム開発アセットの互換性確保
- 3Dプリンター向けデータ最適化
- 他社とのスムーズなデータ共有
日本のCG業界では、DAE形式よりもOBJ形式の方が、特に古いソフトウェアや一部のゲームエンジンで安定して扱えるため、変換の需要が高い傾向にあります。また、OBJはテクスチャパスの調整がしやすく、共同作業でのトラブルが少ない点も評価されています。
About DAE (COLLADA) to OBJ Conversion
Dealing with a DAE file that won't open on your device? You're not alone — DAE compatibility issues are one of the most common reasons people search for a file converter. DAE (Collada) is an open interchange format for 3D assets between digital content creation tools.
The fix is simple: convert your DAE to OBJ. OBJ is a simple 3D geometry format supporting vertices, faces, and texture coordinates. This conversion lets you convert between formats quickly, solving the problem in seconds rather than hours of troubleshooting.
Full Name: DAE uses Collada, while OBJ uses Wavefront OBJ. Compression: DAE uses None (uncompressed), while OBJ uses None (uncompressed). Typical File Size: DAE uses 1–100 MB (XML-based, verbose), while OBJ uses 1–500 MB (text-based, large for complex models). Converting DAE to OBJ maintains high quality with CocoConvert's optimised encoder settings.
CocoConvert processes your DAE 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 When you specifically need a OBJ file for your workflow.
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.
How to Convert DAE (COLLADA) to OBJ
- 1
Add your DAE file
Drag and drop your .dae file into the converter, or tap "Browse" to pick it from your device. Multiple files are supported for batch processing.
- 2
Pick OBJ output
Select .obj as the target format. CocoConvert automatically applies the best quality settings for this conversion.
- 3

Frequently Asked Questions
Why won't my DAE file open?
DAE 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 DAE 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 DAE to OBJ?
Converting DAE 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 DAE 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 DAE to OBJ on my phone?
Absolutely. CocoConvert works in any modern browser — iOS Safari, Android Chrome, and all desktop browsers. No app required.
Versions are pinned in our worker Dockerfile and re-built via CI on every change.
