Free 2D CAD programs that can replace AutoCAD
The free 2D CAD programs that can really replace AutoCAD today are LibreCAD and QCAD Community Edition for pure 2D work, and FreeCAD if you also need 3D. All three are open source and may be used commercially. nanoCAD Free is for non-commercial use, and DraftSight no longer has a free edition. This article compares them plainly, with a table of licences and DWG support.
Before you choose: three questions
Each free program is strong at something different. Answer these three questions first and the list gets short quickly.
- Do you need to open or send DWG files? If customers and contractors always send DWG, your options narrow at once — most open-source programs have limited DWG support.
- Is it for commercial work? Some programs are free only for personal or educational use. If you take paid jobs or use it in a factory, read the licence carefully.
- Only 2D, or 3D one day? If you may later model in 3D and take 2D drawings from the model, starting with a program that does both saves a painful switch.
Comparison table
The table summarises the developers' websites and public information as of October 2026. Licences and prices change; check the official site before deciding.
| Program | Licence / price | DXF | DWG | Platforms | Best for |
|---|---|---|---|---|---|
| LibreCAD | Open source, GPLv2, free | Open / save | Limited | Windows, macOS, Linux | Pure 2D, part drawings, cutting files |
| FreeCAD | Open source, LGPL, free | Import / export | Limited; needs ODA File Converter | Windows, macOS, Linux | 3D design, then 2D drawings |
| QCAD Community Edition | Open source, GPLv3, free | Open / save | Not in the free edition (paid Professional only) | Windows, macOS, Linux | Full-featured 2D |
| nanoCAD Free | Free for non-commercial use | Yes | Native (up to DWG 2013) | Windows | Learning AutoCAD-style commands, personal use |
| DraftSight | Annual subscription (trial available) | Yes | Native | Windows, macOS | A cheaper commercial option |
| DXCAD2D Online | Free, in the browser (offline portable file too) | Import / export R12 | No | Anything with a modern browser | Quick viewing and edits, cutting files |
Each program in detail
LibreCAD
LibreCAD is an open-source 2D drafting program that forked from an old QCAD version. It is licensed under GPLv2 and free for any use, including commercial. It is simple, starts fast and runs on modest computers. DXF is its native format and it can save several versions from R12 to 2007. DWG can be opened partly through the libdxfrw library, but do not expect complex DWG files to come through intact.
It suits part drawings, plates and laser-cutting files. It has no 3D, and some things — such as multiple paper layouts — are less convenient than in commercial programs.
FreeCAD (Sketcher and TechDraw)
FreeCAD is an open-source parametric 3D modeller under the LGPL. Version 1.0 came out at the end of 2024 and releases have continued since. 2D work happens in two places: Sketcher, for constrained sketches (parallel, perpendicular, distances), and TechDraw, for drawings made from the 3D model with dimensions, exported as PDF or DXF.
If you already design in 3D, FreeCAD is the most complete free choice. If you only want to draw 2D lines quickly, it will feel like more steps than a pure 2D program. Opening DWG needs the separate ODA File Converter and is only partly supported.
QCAD Community Edition
QCAD is a 2D program from RibbonSoft. The Community Edition is open source under GPLv3 and free, with a complete set of drafting tools, good layer and block handling and a library of ready-made parts. QCAD Professional is the paid edition, adding DWG read/write, better support for many DXF versions and more tools. Note that some installers bundle a Professional trial; if you only want the free version, download the Community Edition directly.
nanoCAD Free
nanoCAD looks and behaves very much like AutoCAD and uses DWG as its native format. The developer still offers a free download, nanoCAD 5. Its current FAQ describes it as for non-commercial use (some older support pages said otherwise — check the licence you accept when installing), supporting DWG versions up to 2013, and not guaranteed on Windows 10/11 because it predates them. Good for practising AutoCAD-style commands or personal projects; not for paid work or factory use.
DraftSight
DraftSight from Dassault Systèmes used to have a popular free edition, but there is no free version any more — only a trial and annual subscription plans at several levels. It remains a reasonable option for people who need good DWG handling for less than AutoCAD costs, but it is not a "free program" in the sense of this article. If a website offers "free DraftSight", it is an outdated version or a download that did not come from the developer.
DXCAD2D Online
DXCAD2D Online does not try to replace a full installed CAD package. It is for jobs where speed matters: opening a DXF you were sent on a computer without CAD, drawing a plate or flange for the laser shop, or working on a library or school computer where nothing can be installed. Everything runs in the browser, and a single-file portable version works offline. It has a full set of 2D tools (lines, rectangles, circles, arcs, polylines, splines, dimensions, text, hatching, offset, trim, fillet, stretch, arrays, groups, layers) with object snap, intersections and tracking; it opens DXF and PDF and exports DXF R12 (mm), PDF and SVG. Its limits: no DWG, no parametric constraints like FreeCAD, and no 3D.
Which one should you pick?
- Pure 2D, commercial use, no cost: LibreCAD or QCAD Community Edition.
- 3D design with 2D drawings from the model: FreeCAD.
- Paid work that runs on DWG: consider a paid program such as DraftSight, QCAD Professional or a paid nanoCAD edition — the free versions are limited on DWG or on how you may use them.
- Practising AutoCAD-style commands for personal use: nanoCAD Free.
- Viewing, quick edits and cutting files from any computer: DXCAD2D Online.

Open DXCAD2D OnlineFile tips when moving away from AutoCAD
Whatever you choose, use DXF as the exchange file. Ask senders to save as R12 or 2000 for maximum compatibility, and check the units every time you open someone else's file. Text and fonts are what break most often between programs — if a piece of text is to be cut or engraved, convert it to outlines before sending.
