About This Tool

DWF and DWFx are secure, compressed file formats developed by Autodesk for sharing and reviewing drawings. This viewer opens both DWF and DWFx files directly in your web browser. Drag with the left or middle mouse button to pan, and scroll the wheel to zoom toward the cursor. Use the layer panel to show or hide layers. Turn on Measure in the left panel to measure lengths, angles, and areas with smart snapping. All files are decoded locally with WebAssembly, ensuring your drawings remain private on your device.

DWF vs DWG: what's the difference?

DWG is the full, editable source drawing format of AutoCAD. DWF (Design Web Format) is a lightweight, compressed version intended for distribution and review. DWF protects original CAD data while being roughly one-tenth the size of a DWG.

If your DWF drawing looks incomplete

Most display issues result from layer states or font settings inside the original CAD file:

ProblemLikely causeWhat to do
Drawing appears emptyLayers are turned off or geometry is far from the originTurn on all layers in the left panel and double-click the viewport to zoom to extents.
Text labels are missingThe drawing uses custom SHX fonts that were not embeddedWhen exporting DWF from AutoCAD, choose to convert text to geometry or embed fonts.
File fails to openThe file was corrupted during download or exportRe-export a standard DWF or DWFx from your CAD program and try again.

Frequently Asked Questions

View all FAQs

How can I open a DWF or DWFx file without AutoCAD?

Drag the DWF or DWFx file onto this page or click to select it, and the drawing opens in your browser. There is no download, installation, or sign-up required, unlike desktop tools like Autodesk Design Review.

What is the difference between DWF and DWFx?

DWF is Autodesk's original binary format for design web format. DWFx is the modern version based on the Microsoft XPS standard and ZIP packaging. This viewer seamlessly supports both DWF and DWFx.

Can I measure distances in the DWF drawing?

Yes. Turn on Measure in the left panel, then click points on the 2D view. Snap catches endpoints and corners of visible geometry. Length, angles, and areas are calculated directly in drawing coordinates.

Will my DWF file be uploaded to a server?

No. The file is parsed and rendered locally in your browser via WebAssembly and never touches a server, which is essential for confidential client drawings.

Can I turn layers on and off?

Yes. The left panel lists every layer in the file, allowing you to isolate outlines, dimensions, or text annotations easily.

Can I edit a DWF file with this viewer?

No, DWF is inherently a read-only publication format intended for review and verification rather than CAD modification.

About Configuration Options

Layers

OptionWhat it doesDefault / range

Show layer

Show or hide each layer's geometry, text, and dimensions. Hidden or frozen layers in the file start off.on

Measure

OptionWhat it doesDefault / range

Measure mode

What a click sequence measures. Values are in drawing units, not converted to millimeters or inches; up to 50 measurements stay in the list, each can be hidden or deleted. Keys 1, 2 and 3 switch modes.
  • Length: Polyline through 2 or more points; right-click or Enter to finish.
  • Angle: Click the vertex, then one point on each side; shows 0–180°, optionally with the supplementary angle.
  • Area: Closed outline through 3 or more points; right-click or Enter to close.
Length

Snap

Locks clicks to endpoints, corners and midpoints of visible lines, and to the nearest point on a line when zoomed in. S toggles it, hold Alt to ignore it, hold Shift for a wider reach.on

Description:
DWF (Design Web Format) and DWFx are secure, highly compressed file formats developed by Autodesk for distributing and reviewing 2D and 3D design data without full CAD software. DWFx is based on the XML Paper Specification (XPS) format.

Notes:

  • Primarily designed for viewing, measuring, and reviewing drawings
  • DWFx files can also be viewed with standard XPS viewers

Supported Features:

  • Compressed drawing format for design distribution
  • Stores 2D geometry, layers, text, and dimensions
  • Inspect details and toggle layers in browser
  • Suitable for architecture and engineering design reviews
