HTML preview unavailable

Last updated on Jun 2, 2026

HTML content inserted or edited in an Adobe InDesign document shows a static image instead of a preview.

When you insert or edit HTML code in Adobe InDesign, the Insert/Edit HTML dialog displays a static placeholder image instead of a live preview. You’ll view the message Code snippet preview generation is temporarily unavailable.

However, the images or graphics added through the Insert/Edit HTML option will retain the original layout and dimensions and display the right image or graphic after you export the InDesign file.

HTML Preview plugin unavailable

Update InDesign to the latest version.

Install the free plugin Insert HTML Preview for InDesign for Windows or macOS to see the preview.
