Free 3D tools that run in your browser

Open, convert, edit and make 3D files without installing anything — viewers, converters, image and SVG to STL, lithophanes, 3D text and more. When you need a model that doesn't exist yet, the AI 3D Studio makes it.

  • Viewers and converters for 6+ formats
  • Image, SVG and text to STL
  • STL editor, shapes, normal maps
  • Files never leave your device

What are Kenerate's free 3D tools?

Kenerate's free 3D tools are browser-based viewers, converters and makers for 3D files such as STL, GLB and OBJ. They run locally with three.js, so files are never uploaded and no account is needed. Inspect or convert a model, or turn images and text into STL. AI 3D generation is in the 3D Studio (any paid plan or credit pack).

Why this tool

Everything you do with a 3D file, minus the install

Each tool is a focused page, but they share one engine — so a file you can view, you can also convert.

  • A toy astronaut figure turning on a display turntable

    View anything

    Orbit, zoom, clay, wireframe and normals views with triangle, vertex and size readouts.

    Try it
  • A 3D printer nozzle printing a grey dragon miniature layer by layer

    Convert for printing

    STL and 3MF with millimetre sizing and Z-up orientation for slicers.

Also

What else it does

  • Convert for web and AR

    GLB for browsers and engines, USDZ for iPhone and iPad.

  • Private

    Files are parsed on your device. Nothing is uploaded or stored.

  • Works everywhere

    Windows, Mac, Linux, Chromebook, iPhone and Android — any browser with WebGL.

  • Make models with AI

    No file yet? Turn a photo or a prompt into a model with nine engines in the 3D Studio.

How it works

One engine behind every tool

The same four steps power every viewer and converter on this site.

  • Load

    A format-specific three.js loader is fetched only when you open that kind of file.

  • Parse

    Meshes, materials and textures are rebuilt in memory on your device.

  • View

    A WebGL viewer frames the model with studio lighting and shading modes.

  • Export

    Open-source exporters write the format you choose and download it.

Make the model first — from one photo

Every sample in the tool above began as a single picture and was turned into a 3D model in the Kenerate 3D Studio. The engine is named on each one.

Example uses

How creators use the free 3D tools

Illustrative examples of typical workflows, not customer reviews.

  • Lab computer showing a bridge model with its 3D print beside the keyboard

    Student

    A student can open a 3D file from class on any school computer and convert it for the lab printer without installing software.

  • 3D printed brackets, gears and clips on a workshop mat with calipers

    Maker

    A maker can view an STL, fix its size in the editor and convert it to 3MF before printing.

  • Phone showing a 3D potted plant placed on a desk in AR

    AR designer

    An AR designer can convert a GLB to USDZ and show a client the model on their own table.

FAQ
