DWG Viewer — View AutoCAD DWG Files Online, Free
DWG is AutoCAD's proprietary binary format. Live client-side DWG decoding is still pending a licensing decision (see below) — convert to DXF for full viewing today, entities and layers included, with nothing ever uploaded.
1. Choose or drop a file

What this viewer does
- Same orbit/pan/zoom camera controls as the DXF, STL, and STEP viewers
- Clear, honest message (not a silent failure) when a real .dwg is opened
- Download button still works — get your original file back
- Full entity + per-layer rendering is ready to go the moment DWG decoding is enabled
- DXF files opened here render fully today, layers included
How it's rendered
Pending — see note. DWG is AutoCAD's proprietary binary format. The only realistic client-side decoders (WebAssembly ports of LibreDWG) are GPL-3.0 licensed, and bundling GPL code into this site's shipped JavaScript is a licensing decision we haven't made yet — so DWG parsing isn't live. Our DXF viewer shares this same entity/layer renderer and works fully today; most CAD tools can export or convert DWG to DXF.
Nothing about this file is ever sent to a server — open your browser's DevTools Network tab while using this viewer and you'll see no request carrying your file's contents.
100% Private
Files never leave your device. There is no server that ever receives your file's contents.
No Uploads
Every format is decoded and rendered locally via WebAssembly or JavaScript. Open your browser's Network tab and confirm nothing is sent.
No Storage
Nothing is written to a server or database. Memory clears the moment you close or reload the tab.
GDPR-friendly by design
There's no file data collection to comply with in the first place — no account, no tracking of file contents, no analytics on what you view.
DWG viewer — FAQ
What is a DWG file used for?
DWG is AutoCAD's native binary format for 2D and 3D drawings — the most common CAD file format in architecture, engineering, and manufacturing.
Can I actually view a DWG file here right now?
Not yet — live DWG decoding is pending a licensing decision (the only realistic client-side decoders are GPL-licensed). Converting to DXF first gets you full viewing today with nothing uploaded.
How do I convert a DWG to DXF?
AutoCAD itself, and free tools like LibreCAD or Autodesk's own ODA File Converter, can export or convert a DWG file to DXF.
Will layers be preserved once DWG viewing is enabled?
Yes — DWG parsing is planned to feed the same layer-aware entity renderer this site's DXF viewer already uses, so layer toggles would work identically.
Is my drawing uploaded anywhere?
No — even the current DWG detection happens by reading the first few bytes of the file locally; nothing is ever sent to a server.
