What Is a DXF File?
DXF is the documented sibling of DWG. Where DWG is AutoCAD’s compact binary native format, DXF is an open ASCII (or compact binary) representation of the same drawing data, published by Autodesk so every other CAD program can read and write it. The file is a plain-text stream of group-code / value pairs organised into HEADER, TABLES, BLOCKS, ENTITIES, OBJECTS and related sections.
A DXF file carries the same geometry a DWG does — lines, arcs, circles, polylines, splines, text, dimensions, hatches, block inserts, 3D faces, meshes, and ACIS 3D solids — along with the layer table, linetypes, text styles, and blocks the drawing references. If you’ve received a .dxf from an architect, fabricator, or laser-cutter, this viewer opens it in your browser with no AutoCAD or DXF converter required.
Who Uses DXF Files?
Architects, structural engineers, fabricators, and surveyors trade drawings as DXF because it is the most portable CAD format. CNC routers, laser cutters, water-jet machines, plasma cutters, and vinyl plotters consume DXF as their tool path source. Open-source CAD tools like QCAD, LibreCAD, and FreeCAD use DXF as their main drawing format, and GIS packages (QGIS, ArcGIS) import / export DXF for site plans.
Common Use Cases
- Open a DXF received from an architect, engineer, or contractor
- Preview a tool path before sending it to a laser cutter or CNC router
- Inspect a site plan or property survey exported as DXF
- Verify a DXF export from QCAD, LibreCAD, FreeCAD, Rhino, or SketchUp
- Toggle layers, measure distances, and print a paperspace layout
- Share a drawing link without forcing the recipient to install AutoCAD
Features
Open Instantly
Drag and drop a .dxf file — it renders in seconds, right in your browser.
2D & 3D Views
View 2D floor plans and switch to interactive 3D for files with 3DFACE, MESH, or 3DSOLID entities.
Layer Table
Toggle layers on or off to isolate parts of the drawing or filter annotations.
Measure Distances
Click two points to see the exact distance in mm or inches with snap to endpoints.
Hatches & Dimensions
Renders HATCH (solid, ISO, ANSI) and DIMENSION entities — including ARC_DIMENSION and LARGE_RADIAL_DIMENSION variants.
Blocks & Inserts
Block INSERTs with their attributes (ATTRIB) are expanded with their transforms applied.
Share & Embed
Generate a shareable link or an iframe embed to put the drawing on your own site.
Export to PDF
Export the current view as a vector PDF from the toolbar.
No Upload Required
Your DXF is parsed entirely in your browser. Nothing leaves your computer.
Works Everywhere
Desktop and mobile browsers with WebGL — no plugin, no install.
Compatibility & Format Notes
ASCII DXF from AutoCAD R12 through R2018+ (AC1009 → AC1032) is supported. The parser handles the full common 2D entity set (LINE, CIRCLE, ARC, LWPOLYLINE, POLYLINE, SPLINE, ELLIPSE, TEXT, MTEXT, DIMENSION, LEADER, HATCH, SOLID, TRACE), block INSERTs with ATTRIBs, and 3D entities (3DFACE, 3DSOLID/REGION/BODY via ACIS, MESH, POLYFACE MESH).
Binary DXF is detected and reported. Modelspace and paperspace (layout) entities both render. Proxy graphics from vendor-specific entities (Civil 3D, Revit, MEP) are not interpreted — the rest of the drawing still loads.

Your Files Stay on Your Computer
Your DXF files are parsed entirely in your browser. Nothing is uploaded, stored, or shared unless you explicitly click the Share button. Shared files are hosted for 90 days then deleted.
Frequently Asked Questions
▶What's the difference between DXF and DWG?
DWG is AutoCAD’s native binary format — compact and slightly richer. DXF is the open, text-based interchange format Autodesk publishes so other CAD programs can read and write the same data. The geometry is essentially identical; DXF files are larger and slightly slower to parse. See our DWG viewer if you need the binary form.
▶Do I need AutoCAD to open a DXF file?
No. This viewer reads DXF directly in your browser — no AutoCAD, DWG TrueView, or converter required. It works on Windows, macOS, Linux, ChromeOS, iPad, and Android in any modern browser.
▶Which DXF versions are supported?
ASCII DXF from R12 (AC1009) through R2018+ (AC1032) loads, covering essentially every DXF file you’ll receive in the wild. The version is read from the $ACADVER header so the viewer can apply per-version quirks (entity handles, extended data, hatch pattern definitions).
▶Does the viewer support 3D DXF files?
Yes. 3DFACE, POLYFACE / POLYGON MESH, and MESH entities render directly. 3DSOLID, REGION, and BODY entities embed ACIS (SAT/SAB) data — the viewer extracts and tessellates their wireframe; click the 3D toggle in the toolbar to orbit the model.
▶Are hatches and dimensions rendered?
Yes. Solid-fill hatches, ISO and ANSI pattern hatches, and DIMENSION entities (including ARC_DIMENSION and LARGE_RADIAL_DIMENSION variants) all render. Try the “Solid-fill hatches” and “ISO pattern hatches” samples in the toolbar to see them.
▶Can I send a DXF to a laser cutter from this viewer?
The viewer doesn’t drive cutters directly, but it does let you verify a tool path before you upload it — toggle layers, measure distances, switch to a top view, and print or export to PDF. If your fabricator wants DWG instead, our DWG viewer opens those too.
▶What about binary DXF?
Binary DXF (the “AutoCAD Binary DXF” sentinel) is detected. ASCII DXF is by far the more common variant and what virtually every CAD package exports by default; if you have a binary DXF, re-saving it as ASCII from your source CAD program ensures the broadest compatibility.
▶Is this DXF viewer really free?
Yes, completely free. No signup, no watermarks, no file size limits on the viewer (the optional share-link feature has a 30 MB upload cap). Built by Innerscene as a tool for architects, engineers, and designers.
▶Are my files uploaded to a server?
No. All parsing, rendering, and conversion runs in your browser — nothing is uploaded, stored, or transmitted by default. The Share button is the only feature that uploads a file, and only when you explicitly click it.
▶Can I convert to another format?
Yes. Click Export in the toolbar to save as STL (3D printing), OBJ (Wavefront), GLB (glTF binary), or PDF (snapshot of the current view).
▶Can I embed this viewer on my own site?
Yes. Click Embed in the toolbar to generate a one-line <iframe> snippet you can paste into any HTML page. You can choose whether the embed shows the viewer’s toolbar.
