Is my GLB uploaded to a server?
No. The GLB to STL conversion runs locally in your browser and the model never leaves your device.
Free GLB to STL Converter
Convert GLB to STL locally for geometry-only 3D printing checks, slicers, and manufacturing review.
Browser-only, private
Convert GLB to STL locally for geometry-only print prep.
How to convert GLB to STL
The conversion runs in this browser tab, so you can check the mesh before it reaches a slicer.
Pick the GLB file
Choose the GLB you want as a printable mesh. Files up to 50 MB are read on your device, so the model is not uploaded.
Convert to STL
Press Convert model. Only triangle geometry is written to the STL, so textures, colors, materials, rigs and animations are dropped.
Download the STL
Save the converted file to disk before you close the tab. The converted mesh exists only in this browser session.
Verify it in your slicer
Open the STL in your slicer and confirm scale, orientation, wall thickness and manifold edges before printing.
GLB to STL questions
1 2 What is lost when a GLB becomes an STL?
STL output stores geometry only. Textures, colors, materials, rigs and animations are discarded, so a painted GLB turns into a bare printable surface.
3 How large can the source GLB be?
Up to 50 MB per file. Larger models need a desktop conversion tool.
4 Which conversions can this tool handle?
GLB to OBJ, GLB to STL, OBJ to GLB, and STL to OBJ.
5 Do I need an account or an install?
No. The converter is free and needs no sign-up; a current Chrome, Edge, Firefox or Safari build with WebGL is enough.
Quick tips
- STL output stores geometry only; textures, colors, materials, rigs, and animations are discarded.
- After conversion, inspect the STL in your slicer before printing.

- Turn One Photo into a Gaussian Splat File | TripoSplatUpload one clear photo when you want to orbit the subject. TripoSplat downloads a Gaussian splat as PLY or SPLAT, not a printable mesh. Open the generator next.
- Image to 3D Without a Local GPU | TripoSplat GuideThe generator page says you do not install a local GPU. TripoSplat turns one image into a Gaussian splat and lets you download PLY or SPLAT. Start on one image.
- A Gaussian Splat Is Not a Printable Mesh | TripoSplatA PLY or SPLAT splat is for turning a subject around in the browser. It is not an STL solid. Read this before you send the file to a printer. Not a solid part.
- Open a PLY or SPLAT File in the Browser | TripoSplatIf you already have a PLY or SPLAT file, open the free viewer. That path does not spend a generation credit. Use the generator only when you still have a photo.
- Questions Before You Buy Image-to-3D Credits | TripoSplatBuy credits only after you know the download is a Gaussian splat. This page lists the questions to ask. Prices and pack sizes stay on the pricing page.
- Photo to 3D File: a Splat Is Not Always a Mesh | TripoSplatThe phrase from a photo to a 3D model is ambiguous. TripoSplat publishes a Gaussian splat as PLY or SPLAT. A mesh for editing or printing is a different file.
- One Lighter 3D Preview Before You Create an AccountThe generator says the first run is a lighter preview, one per visitor, with no sign-in. Later runs stay in account history. This page quotes no credit grant.
- Frame the Subject Before Image-to-3D | TripoSplat GuideA small subject in a busy photo is a common reason a splat looks empty. Crop so the subject fills the frame, then upload that one image to the generator.
- View a File You Have, or Generate a New Splat | TripoSplatUse the free PLY viewer when the file already exists. Use the generator when you only have a photo. This page keeps those two jobs on two different buttons.
- Ask If Image to 3D Means a Splat or a Mesh | TripoSplatWhen you ask an assistant for image to 3D, ask what file comes back. TripoSplat's published answer is a Gaussian splat as PLY or SPLAT, not a print-ready mesh.
