View STL, OBJ and 3DS 3D files quickly from your local computer. 3D Viewer for Google Chrome™ — View STL, OBJ, 3DS, PLY, GLB/GLTF and 3MF files instantly Open and inspect 3D models right inside your browser — no uploads, no sign-up, and nothing to install. 3D Viewer for Google Chrome is a fast, private way to preview 3D files straight from your own computer, whether you are a 3D-printing hobbyist, a product designer, an engineer, a teacher, or simply curious about a model someone sent you. Just click the toolbar icon, choose a file (or drag and drop it onto the window), and your model appears in seconds — ready to rotate, zoom, measure, and analyze. This is a major new release, rebuilt from the ground up on a modern 3D engine for better speed, stability, and quality. If you used an older version, you will notice models load faster, render more cleanly, and keep working reliably even after opening many files in a row. WHAT YOU CAN OPEN We now support far more than STL and OBJ: • STL (binary and ASCII) — the 3D-printing standard • OBJ — common mesh exchange format • 3DS — legacy 3D Studio models • PLY — including per-vertex colors • GLB / glTF — modern format with full materials and embedded textures • 3MF — the modern 3D-printing format with colors and materials COLOR AND TEXTURE, NOT JUST GREY SHAPES Older viewers (including our previous version) showed everything as a single flat color. Now your models render with their own materials: glTF/GLB physically based materials and embedded textures, PLY vertex colors, and 3MF colors all display the way they were designed. Soft, realistic lighting makes detailed models look great straight out of the box. EFFORTLESS TO USE • Drag and drop any supported file anywhere on the window • Or use the file picker — only valid 3D formats are offered • A Recent list remembers your last files for quick access • Save a high-resolution PNG snapshot of the current view with one click • Works fully offline — your files never leave your device POWERFUL VIEW AND RENDER CONTROLS Get exactly the view you need: • Render modes: Solid, Wireframe, Edges, and Points • One-click standard views: Fit, Top, Front, Right, and Isometric • Toggle a ground grid and XYZ axes for orientation • Choose a background (Dark, Light, Blue, or Black) and recolor the model with a color picker • Smooth mouse orbit, pan, and zoom BUILT-IN MEASURE TOOL Turn on Measure, click two points on the surface of your model, and instantly read the straight-line distance between them in your chosen units — perfect for checking dimensions before you print. MODEL INFORMATION AND PRINTABILITY CHECKS Every model shows useful details at a glance: • Triangle count and unique vertex count • Watertight check with open-edge detection — quickly see whether a mesh is "manifold" and ready to print, or whether it has holes that need repair • Overall bounding-box size A REAL 3D-PRINTING ESTIMATOR This is more than a viewer — it is a planning tool for makers. Load a model and get an instant estimate of material use and cost: • Pick a material preset (PLA, PETG, ABS, ASA, TPU, Nylon, or Resin) to set typical density and price, or enter your own custom values • Set infill percentage, filament diameter, print speed, and price per kilogram • Choose your model units (mm, cm, or inches) so volume, weight, and dimensions are always correct — even for files authored in inches • See estimated weight, filament length, build time, and total print cost update live Your material, units, and printer settings are remembered between sessions, so the estimator is ready to go every time. SPEED, STABILITY, AND ACCURACY This release fixes the issues that mattered most: • Resolved the long-standing problem where the viewer could stop rendering after opening several models — memory and graphics resources are now released properly on every load • Corrected the filament-length and print-time math so estimates are physically accurate • Clear, specific error messages when a file is unsupported, corrupt, or cannot be read, instead of a generic failure • A faster, more responsive interface that scales to your window PRIVATE BY DESIGN Everything happens locally in your browser. Your 3D files are never uploaded, shared, or stored on any server, and the extension collects no personal data. It also works without an internet connection. AVAILABLE WORLDWIDE The interface is localized and falls back gracefully to English, so users around the world get a clean, readable experience. WHO IS IT FOR • 3D-printing enthusiasts checking models, dimensions, material use, and cost before printing • Designers and engineers who need a quick, no-fuss preview of mesh files • Educators and students exploring 3D geometry • Anyone who receives a 3D file and just wants to see it — fast Install 3D Viewer for Google Chrome and open your first model in seconds. No accounts, no uploads, no hassle — just your 3D files, instantly. This extension is not affiliated with or endorsed by Google. Google Chrome is a trademark of Google LLC.
