Free Online DXF Viewer
Open and measure DXF files directly in your browser. 100% client-side — your files never leave your device. No installation, no signup.
Three steps to view any DXF file
Drop your DXF file
Drag and drop a .dxf file onto the viewer, or click to browse. Your file stays on your device — nothing is uploaded.
Explore and measure
Zoom, pan, toggle layers, and measure distances with snap-to-geometry precision. Units are detected automatically from the DXF header.
Export or share
Download a high-resolution PNG screenshot — including measurements — to share with colleagues. Your original file never leaves your browser.
Who uses an online DXF viewer?
Open DXF files online
Quickly open and inspect DXF drawings shared by colleagues or contractors. No software to install — just drop the file and review layers, geometry, and dimensions in your browser.
Review confidential CAD files privately
NDA-protected designs and pre-patent drawings stay on your device. This free DXF viewer processes everything client-side — zero network requests with your file data.
Replace paid desktop CAD viewers
Teams that only need to view — not edit — DXF files can skip expensive CAD licenses. Measure distances, toggle layers, and export PNGs without any desktop software.

What is the DXF file format?
DXF (Drawing Exchange Format) is an open CAD file format created by Autodesk in 1982 to enable interoperability between AutoCAD and third-party software. Unlike the proprietary DWG format, DXF uses a documented specification available in both human-readable ASCII and compact binary variants. This openness has made DXF the lingua franca of CAD file exchange — virtually every CAD, GIS, and engineering application can import and export DXF.
DXF files are widely supported across AutoCAD, BricsCAD, QCAD, LibreCAD, FreeCAD, Rhino, SketchUp, SolidWorks, Fusion 360, and many other platforms. When teams use different CAD software — common in cross-organizational collaboration — DXF is the natural choice for sharing drawings without losing geometric fidelity. The format preserves lines, arcs, circles, splines, text, dimensions, hatches, block references, and layer structures.
Because DXF is an open format, this viewer parses and renders your file entirely in the browser using client-side JavaScript and WebGL. Zero network requests are made with your file data, which means your drawings never leave your device. This makes the viewer safe for NDA-protected designs, pre-patent drawings, and confidential infrastructure plans that cannot be uploaded to cloud services.
Need to open a DWG file?
DWG files require a brief server-side conversion. The viewer converts securely and deletes your file immediately.
