DWG Online Viewer
Open AutoCAD DWG drawings instantly in your browser. Pan, zoom and inspect lines, arcs, text and layers — private, free and no CAD software required.
View DWG files the easy way
Instant, in-browser viewing
Drop a DWG and the drawing appears right away — no uploads, no software, no waiting for a server to convert it.
Pan & zoom controls
Drag to pan, scroll to zoom, or hit fit-to-view to frame the whole drawing. Inspect fine details or survey the full layout.
Renders real geometry
Lines, polylines, circles, arcs, ellipses, splines, text and blocks are converted and drawn accurately from the original DWG data.
Layer & color aware
Entity colors, layer colors and true colors are respected, so the on-screen view matches the intent of the original drawing.
Private by design
Everything runs locally in your browser with WebAssembly. Your DWG files are never uploaded to any server.
Batch friendly
Drop up to 10 drawings at once — each one is converted and rendered automatically, ready to inspect side by side.
About DWG viewing in the browser
DWG is AutoCAD's native drawing format and one of the most widely used file types in engineering, architecture and manufacturing. For decades, opening one meant owning a full CAD workstation. This viewer removes that barrier: it reads the DWG file's geometry in your browser with GNU LibreDWG compiled to WebAssembly, then draws every entity — lines, arcs, polylines, ellipses, splines, text and nested blocks — onto a canvas you can pan and zoom freely. Because the conversion happens on your device, there is no upload, no queue and no server-side file size limit. Whether you're reviewing a contractor's plan, checking a supplier drawing or just need a quick look without buying software, this is the fastest way to view a DWG online.
How to view a DWG file online
Three simple steps — no account, no software, no upload.
Drop your DWG
Drag one or more .dwg files onto the upload area, or click to browse. Each drawing converts automatically — no button needed.
Wait a moment
The DWG is converted to drawing geometry locally in your browser using WebAssembly. Small files open in a blink; larger files take a second or two.
Inspect & navigate
Every file appears as a card below the dropzone. Drag to pan, scroll to zoom, or use the toolbar to fit the whole drawing in view.
A note on DWG versions
The DWG format changes with every AutoCAD release, and a handful of files use structures that the open-source converter can't fully read — usually very new versions or drawings produced by third-party CAD software. In those cases the tool reports the failure honestly rather than showing a blank or wrong drawing. For broad compatibility, save a copy of the drawing in AutoCAD's R2000 (AC1015) format — it converts perfectly every time.
