.indd · .indt for Windows 10 and 11
See your InDesign documents in Windows Explorer.
Real thumbnails for every .indd document and .indt template, a working Preview pane, and a right-click Preview window. No InDesign required, nothing leaves your PC.
Windows 64-bit · 1-day trial, all features
Thumbnails that are the file
The first-page preview InDesign saves inside the document. Documents saved without one show a clear placeholder.
Details at a glance
The preview pane lists the InDesign version that saved the document, its fonts and the size of its preview.
Never takes over
InDesign still opens your documents. We only add a thumbnail and a preview, alongside whatever else you use.
How it works
Three things Windows should have done on its own. Everything runs locally, inside Explorer.
Install
Run the installer. It adds a thumbnail provider and a preview handler for .indd, .indt to Windows Explorer. The app that opens those files stays exactly as it is.
Open a folder
Explorer draws real thumbnails right away. Switch to Large or Extra large icons to see them best.
Preview and inspect
Turn on the Preview pane (View › Preview pane, or Alt+P) to see a file without opening it, with its details underneath. Or right-click and choose Preview for a larger window.
Simple pricing
One-time purchase. No subscription, no account.

Questions
Do I need InDesign installed?+
No. Thumbnails come from the page preview InDesign saves inside the document.
Why does a document show "No saved preview"?+
It was saved without one. In InDesign, turn on Preferences > File Handling > Always Save Preview Images with Documents, then save it again.
Does it edit or convert my files?+
No. It only reads them to draw a thumbnail or preview. Files are never modified, and nothing is uploaded anywhere.
Which versions of Windows are supported?+
Windows 10 (1809 or later) and Windows 11, 64-bit. The installer is a standard MSI; Microsoft Store editions are on the way.
What happens after the 1-day trial?+
Thumbnails and the preview pane pause and the preview pane shows a purchase link. Enter a license key and everything resumes, with no reinstall.
Can I use one license on more than one PC?+
A license covers one Windows PC. Buy one license per machine; reinstalling on the same machine is fine.
Why do some thumbnails not appear right away?+
Windows caches thumbnails and fills large folders in the background. Refreshing (F5) speeds it up, and Settings › Maintenance can clear the cache.
