STL Converter Online: STL, OBJ, 3MF, GLB and PLY
Switch any 3D model between STL, OBJ, 3MF, GLB and PLY, and rescale it at the same time. The conversion happens in your browser, so nothing is uploaded.
Quick start
- Load an STL, OBJ, 3MF or PLY model.
- Pick the format you need and, optionally, a scale in percent.
- Press “Convert & download” and the new file is saved right away.
Which format do I need?
- STL: universal, every slicer reads it.
- 3MF: ideal for Bambu Studio, Orca and PrusaSlicer.
- OBJ: for Blender and other 3D software.
- GLB: for web viewers, AR and game engines.
- PLY: for MeshLab and scan data.
Scale while you convert
Type 150% to make the model one and a half times bigger, or 25% for a quarter size. The original dimensions are shown, so working out the right scale is easy.
Questions & answers
Do you keep a copy of my model?
Never. The file is opened by your own browser and is not sent to any server, which makes the tool safe for commissioned, paid or unreleased models.
Does it cost anything?
No. There is no account to create, no watermark and no limit on how many files you open.
Will a 3MF from this tool open at the right size in Bambu Studio?
Yes. The 3MF is written in millimeters, so Bambu Studio, Orca Slicer and PrusaSlicer open it at its true size.
Can it turn OBJ or 3MF into STL?
Yes. Load the file and choose STL. Binary STL is the most compact; ASCII STL can be read as plain text.
Do colors and textures survive?
No. Only the geometry is exported, which is what a printer uses. Colors, textures and slicer settings are dropped.
