Open DWG files online without AutoCAD
A DWG file is the native binary drawing format used by AutoCAD and many other CAD applications. A drawing can contain geometry, blocks, text, dimensions, layers, model space and paper-space layouts used across architecture, engineering, construction and manufacturing.
Flinker is a browser-based DWG viewer for quick drawing review. Choose a .dwg file to pan, zoom, switch layers and layouts, and take snapped distance measurements without downloading desktop CAD software. Processing happens locally on your device, so confidential plans are not transferred to an upload server. The tool is designed for viewing and inspection; it does not edit or save DWG geometry.
Open a real CAD project
Try a complete DXF drawing. It opens locally in your browser and is never uploaded.
Architectural site plan
537 KB project with 707 entities, 13 layers, terrain and annotations.
Curtain wall construction
2.7 MB façade detail with 1,244 entities, 22 layers and dimensions.
Remote sample sources: dxf-json, dxf, and dxf-parser.
How to view a DWG file online
Open a drawing in three steps. You do not need an account, browser plugin or CAD installation.
Choose your drawing
Select a .dwg or .dxf file from your device, or drag it directly onto this page.
Process it locally
WebAssembly reads and converts the drawing inside your browser instead of sending it to a server.
Inspect and measure
Pan, zoom, control layers, switch layouts and measure distances with line and vertex snapping.
Free online DWG viewer features
Review real CAD drawing data, not a flattened thumbnail, including lines, polylines, circles, arcs, splines, dimensions, text and blocks.
DWG & DXF support
Open binary DWG drawings and ASCII DXF exchange files from the same file picker.
Layers & layouts
Show or hide drawing layers and switch between model space and paper-space layouts.
Accurate measurement
Measure drawing distances with vertex and line snapping for repeatable review.
Private by default
Conversion and rendering run locally on your device; files are never uploaded for viewing.
Browser-based DWG viewer for Windows, Mac and Linux
Use Flinker in a current Chrome, Edge, Firefox or Safari browser with JavaScript, WebAssembly and WebGL enabled. There is no desktop viewer to download and no browser extension to install. Large or complex drawings work best in a 64-bit desktop browser with enough free memory.
- Drawing navigationPan, zoom and fit the complete CAD drawing in the viewer.
- Drawing structureInspect layer visibility, model space and paper-space layouts.
- Review toolsMeasure distances with vertex and line snapping.
- Private processingRead DWG and DXF data locally without an upload step.
Which DWG versions can I open?
The viewer supports DWG R13 (AC1012), R14 (AC1014), 2000-2002 (AC1015), 2004-2006 (AC1018), 2007-2009 (AC1021), 2010-2012 (AC1024), 2013-2017 (AC1027), and 2018 or later (AC1032).
Application-specific custom objects, proxy graphics and external references may not render exactly as they do in the authoring software. If a drawing is incomplete, bind its references or export an ASCII DXF and open that file instead.
DWG vs DXF: what is the difference?
| Comparison | DWG | DXF |
|---|---|---|
| Purpose | Native working drawing | CAD data exchange |
| Encoding | Compact binary data | Usually readable ASCII text |
| Typical size | Usually smaller | Usually larger |
| Best used for | Complete project drawings | Moving geometry between CAD tools |
Online DWG viewer FAQ and troubleshooting
Verify the file type+
Confirm the extension is .dwg or .dxf.
Check its DWG release+
Use R13 through R2018/AC1032.
Use a desktop browser+
Large drawings need more memory.
Export an ASCII DXF+
Use DXF when a proprietary object cannot be converted.
Is this online DWG viewer free?+
Yes. You can open and inspect DWG and DXF drawings without payment, signup or installation.
Do I need AutoCAD to open a DWG file?+
No. The browser viewer lets you inspect a drawing without AutoCAD or another desktop CAD installation.
Are DWG files uploaded to a server?+
No. DWG and DXF files are processed locally in your browser and never uploaded to a server.
Can I use this DWG viewer on Windows, Mac or Linux?+
Yes. The viewer runs in current Chrome, Edge, Firefox and Safari browsers on Windows, macOS and Linux. Large drawings work best in a 64-bit desktop browser.
What is the maximum DWG file size?+
There is no fixed file-size limit. Practical capacity depends on device memory, drawing complexity and browser resources.
Can I edit and save DWG files here?+
No. Flinker is a viewer for inspecting drawings. Use a CAD editor when you need to change and save geometry.
Why are referenced drawings or objects missing?+
External references and application-specific proxy objects may not be embedded in the DWG. Bind the references or export a flattened DXF from the authoring application.
