DXF viewer

Choose a DXF for a read-only look, without opening an editor.

Up to 64 MB per DXF, matching the online editor. No upload or sign-in.

Use this page just to view a DXF. To edit geometry or save a drawing, use the online editor.

ASCII or binary?

Before opening a DXF, inspect its first line in a text editor. A readable group code such as 0 followed by SECTION identifies ASCII DXF; a 999 comment may come first. If the bytes begin with AutoCAD Binary DXF followed by control characters, it is binary. Changing the filename does not change the encoding.

The header’s $ACADVER value identifies the saved format. ASCII R12–2018 is readable here; binary requires R13 or newer, through 2018. Binary R12 cannot be read. A headerless ASCII file can also open if its ENTITIES section is valid.

Which DXF versions open here

These are file-format revisions, not the year the file was received. Supported format does not guarantee every custom object or layout will look identical. The input limit is 64 MB, using the same limit as the online editor.

Why text looks different

When the original SHX font is unavailable, CADCraft substitutes its single-line stroke font. Different character widths can shift labels and change wrapping. The preview does not upload or locate the sender’s font files, and it is not an exact typography check.

You can set a TrueType substitute with SETVAR FONTALT in the online editor or desktop app, choosing a font with the characters you need. Inspect alignment and line breaks after substituting; this read-only page does not change the original drawing or its text styles.

DXF viewer FAQ

Can I view a DXF on my phone?

A current mobile browser with WebAssembly and WebGL2 can try small drawings. Drag to pan, pinch or use the zoom buttons. Large files can exhaust phone memory; use a desktop browser for complex drawings.

Will my DXF be uploaded?

No. The existing CADCraft reader and plotter run on your device. The page downloads application assets but does not send your drawing to a server or store it in a cloud account.

What if the DXF will not open or looks blank?

Check the ASCII/binary format and version first: binary R12 is unsupported. Use Fit drawing after zooming. This viewer shows 2D model-space geometry, so a paper-space-only file or unsupported objects can look empty. If the reader fails, check WebAssembly/WebGL2 support or inspect the file in the desktop app.

What is the maximum DXF file size?

The input limit is 64 MB (67,108,864 bytes), using the same limit as the online editor. Device memory can impose a lower practical limit. The 20 MB DWG limit is for DWG input, not DXF.
