Batch Settings
3Dモデルのデータ形式変換は、デジタルものづくりにおいて避けて通れない作業の一つです。特にSTL形式は3Dプリンターで広く利用されていますが、アニメーション制作やより複雑なシーン構築には不向きな点もございます。そこで、Collada形式（DAE）への変換が重要になります。DAEは、モデルの形状情報だけでなく、色、テクスチャ、アニメーションといった多様なデータを保持できるため、表現の幅が格段に広がります。当社の変換ツールは、お客様の大切な3Dデータを損なうことなく、スムーズかつ高精度にDAE形式へと変換いたします。直感的な操作性で、技術的な知識がなくても安心してお使いいただけます。この変換を通じて、皆様の創造的なプロジェクトがさらに豊かなものとなるよう、心より願っております。

- 建築パースの多機能なプレゼンテーション
- ゲーム開発におけるアセット流用
日本のアニメ・ゲーム業界では、3Dモデルの互換性がプロジェクト進行の鍵となることが多く、DAE形式はその中間フォーマットとして重宝されています。
About STL to DAE (COLLADA) Conversion
Short answer: yes, you can convert STL to DAE online for free, and quality is well preserved with the right settings. Just upload your .stl file to CocoConvert, pick DAE as the output, and click Convert. The whole process takes seconds.
Now for the details. STL stores 3D surface geometry as triangulated meshes — the standard for 3D printing. DAE (Collada) is an open interchange format for 3D assets between digital content creation tools. Converting between these two formats lets you convert between formats quickly.
Full Name: STL uses Stereolithography, while DAE uses Collada. Compression: STL uses None (uncompressed), while DAE uses None (uncompressed). Typical File Size: STL uses 1–100 MB, while DAE uses 1–100 MB (XML-based, verbose).
Your STL file is decoded and re-encoded as DAE. Converting STL to DAE 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 STL to DAE conversion free?
Yes. CocoConvert offers free STL to DAE 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 STL to DAE 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 STL file and the converted DAE file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting STL to DAE lose quality?
Converting STL to DAE maintains high quality with CocoConvert's optimised encoder settings.
Can I convert DAE back to STL?
Yes, CocoConvert supports DAE to STL conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
Versions are pinned in our worker Dockerfile and re-built via CI on every change.
