Why convert SHX to TTF?
An AutoCAD Compiled Shape/Font File stores glyphs as compact binary vector stroke commands in AutoCAD's own shape language - not as Bezier curves or any outline format a TrueType font engine understands. A TrueType font stores quadratic Bezier outlines in structured binary tables. Converting between these would require interpreting each shape command and rebuilding valid font tables from scratch, which no mainstream tool does.
How to convert SHX to TTF
AutoCAD APP
If you have the original .shp source, edit it in a text editor and recompile with the COMPILE command in AutoCAD - this updates the .shx for continued use within the CAD environment rather than converting to TTF.
About these formats
An SHX file is a compiled shape and font definition that AutoCAD uses to draw custom text styles and symbols in a drawing. You don't open it directly - you place it in AutoCAD's Fonts or…

Open .TTF details →Quality & what to watch
- AutoCAD also supports TrueType fonts - you can assign a
.ttfto a text style instead of an.shx, which is the modern approach for fonts needed outside CAD. - If the same typeface was released as a TTF by its original designer, search by font name rather than trying to extract one from the
.shx. - The
.shxformat was designed for fast vector rendering in AutoCAD's 1980s drawing environment, not for use as a system font outside CAD.
Frequently asked questions
Are there any tools that convert .shx to .ttf?
How do I use an .shx font in AutoCAD without converting it?
.shx file into AutoCAD's Fonts folder and assign it to a text style; no conversion is needed for in-CAD use.Why does AutoCAD use .shx instead of standard fonts?
.shx format predates TrueType and was optimized for the vector drawing hardware of the 1980s; AutoCAD supports TTF fonts today as a modern alternative.
