When you look at a diagram exported to an SVG image in IE or some SVG editors, the text may not display correctly.

diagrams.net uses something called foreign objects in SVG to allow complex, HTML labels on shapes.


All modern browsers including Chrome, Firefox, Safari and Microsoft Edge support this functionality. Internet Explorer 11 and earlier versions of IE do not.


We can account for this dynamically if you use diagrams.net in IE11 or earlier. However, the exported SVG will not show all labels when the SVG image file is viewed in IE and most SVG editors (such as Inkscape and Illustrator), as well as some online services such as Wordpress. Instead, you will see an error [Not supported by viewer] instead, or a parse error if you are trying to view the SVG file in WordPress.


We are aware of the problem and have spent a considerable amount of time researching solutions. However, the subject is very complex and we don’t have a fix so far. We will continue to investigate it.


In the meantime, consider exporting your diagram to a PDF file as this is also a vector format, or disable formatted text and word wrapping for all labels in your diagram before you export it to SVG by following the steps below.

  1. Right click on a blank area of the drawing canvas, then choose Select All from the context menu.
  2. In the Text tab of the format panel, uncheck the Formatted Text option.
  3. Right click on a blank area of the drawing canvas, then choose Select Vertices.
  4. In the Text tab of the format panel, uncheck the Word Wrap option.

Note: When you disable these formatting options, you can still style the label text as a whole. You can not apply different formatting to parts of the label.
