Common issues
If a dataset uses multiple required sidecar files, make sure you provide the complete set together. For best results, keep all sidecars in one zip archive when applicable.

Open AutoCAD DWG without QGIS or ArcGIS
You do not need QGIS, ArcGIS Pro, ArcMap, or any desktop GIS software to open and inspect AutoCAD DWG files. This page is a browser-based AutoCAD DWG viewer: it loads your file locally, renders the geometry and attributes on an interactive map, and never uploads your data to a server. If you just need to look at a dataset, check coordinates, or share what you see, you can skip the desktop GIS install entirely.
- ✓ No installation — open AutoCAD DWG directly in Chrome, Firefox, Edge, or Safari.
- ✓ No QGIS license, ArcGIS Pro subscription, or ArcMap setup required.
- ✓ Private by default — files are processed on your device, nothing is uploaded.
- ✓ Instant preview — drag a file in and see the map render in seconds.
- ✓ Good for one-off checks: a quick look at attributes, geometry, or extent before deciding whether to open the data in a full GIS.
If you later need advanced analysis, editing, or geoprocessing, you can still open the same AutoCAD DWG file in QGIS (free and open source), ArcGIS Pro, ArcMap, or Global Mapper — but for viewing and quick checks, this online AutoCAD DWG viewer is all you need.

How do I open a AutoCAD DWG file online?

Can I open AutoCAD DWG without QGIS or ArcGIS?
Yes. This page is a free online AutoCAD DWG viewer that runs entirely in your browser — no QGIS installation, no ArcGIS license, and no plugins. Just add your AutoCAD DWG file and it is rendered locally on an interactive map.
Do I need ArcGIS to view AutoCAD DWG files?
No. ArcGIS is one option for working with AutoCAD DWG, but it is commercial software and overkill if you only need to view a file. GeoDataViewer opens AutoCAD DWG in your browser for free, with no account and no upload, so you can inspect the data before deciding whether a full GIS is worth it.
Can I open AutoCAD DWG without ArcGIS Pro or ArcMap?
Yes. ArcMap has been retired by Esri and ArcGIS Pro requires a paid subscription, but neither is needed to view AutoCAD DWG files. This browser-based AutoCAD DWG viewer opens your file locally for free — no ArcGIS Pro license, no ArcMap install, and no account required.
Is there a free AutoCAD DWG viewer with no installation?
Yes — this page. GeoDataViewer is a completely free AutoCAD DWG viewer that runs in your browser. There is nothing to install and nothing to download: open the page, add your AutoCAD DWG file, and inspect the map and attributes immediately.
Is GeoDataViewer a QGIS alternative?
For viewing, inspecting, and converting AutoCAD DWG files, yes — GeoDataViewer covers those needs entirely in the browser with zero setup. QGIS remains the better choice for deep analysis, geoprocessing, and large production workflows. The two complement each other: use this viewer for quick checks and QGIS when you need the full toolbox.
