You have words or artwork
Use the 3D text generator for raised lettering, or SVG to 3D to give a vector shape depth.
For a photo that lights up from behind, make a photo lithophane.

OpenWhich 3D tool do you need?
You already have a 3D file
Open it in the 3D model viewer before converting. Check the shape, orientation, and visible surfaces.
Choose a converter above when your next app needs OBJ or STL.
You want a new object from a photo
Use image to 3D for an AI-generated object, or text to 3D to start from a description.
Need a static mesh for editing? Create OBJ from an image and keep the material files together.
AI generation uses credits. See Quady3D model examples and plans and generation costs.
Know what changes during conversion
A new file format does not repair a mesh or make it ready to print.
| Conversion | What you get | What to check |
|---|---|---|
| OBJ to STL | Mesh geometry for a slicer. | STL drops materials and textures. Check size and closed surfaces. |
| GLB to STL | Static mesh geometry from a GLB. | Materials, textures, and animation are not included. Review thin parts before printing. |
| GLB to OBJ | An OBJ mesh for static editing. | Embedded materials and textures are not packaged into an MTL or texture folder. |
Set the intended size again in your destination app. For printing, follow the 3D print preparation guide and check the result in a slicer.
Questions about the free 3D tools
Are these 3D tools free?
Yes. The creators, viewers, and converters in this directory are free, run in your browser, and need no account or generation credits. AI model generation is a separate workflow that uses credits.
Are my files uploaded?
The tools in this directory process selected files on your device. You can preview or convert a local file without uploading it to Quady3D.
Which file formats can I use?
The 3D model viewer accepts GLB, glTF, OBJ, and STL. Converters cover OBJ to STL, GLB to STL, and GLB to OBJ. Creation tools accept text, SVG, or supported images; each card lists its inputs and downloads.
Does conversion preserve textures and animation?
No. STL stores geometry only. The GLB-to-OBJ export does not package embedded materials or textures into an MTL or texture folder, and it does not preserve animation. Check the intended size in your destination app.
Can these tools repair a model or make it ready to print?
A viewer or file conversion does not repair geometry. Before printing, check size, closed surfaces, and thin parts in a slicer. A photo lithophane creates a relief; it does not reconstruct a complete object from the photo.
