DjVu thumbnails in Windows Explorer
SageThumbs 2K shows DjVu documents in File Explorer as a picture of their first page. It decodes DjVu itself with a pure-Rust decoder, so no DjVu viewer or plug-in has to be installed.
What you see
- When the file carries a pre-rendered page thumbnail, that is used. Otherwise SageThumbs renders the first page: background, anti-aliased text and colours.
- Multi-page books whose pages share a dictionary are handled.
- Large DjVu books are not loaded whole; the first page is still shown.
Limits
- The thumbnail shows the first page only.
- In OneDrive and other synced folders, files stored on the PC get thumbnails as anywhere else. Online-only files are left to the cloud app, since nothing is downloaded just to draw a thumbnail.
More you can do
- In Quick preview, Copy text (OCR) reads the words off a scanned DjVu page and puts them on your clipboard.

Thumbnails not showing?
- Windows caches thumbnails, and a file it failed on once stays failed. In SageThumbs, Settings ▸ Advanced ▸ Rebuild thumbnail cache clears the cache and restarts Explorer.
- Make sure File Explorer's "Always show icons, never thumbnails" option is off, and that the format is ticked in SageThumbs Settings ▸ File types.
- Run
st2k doctorin a terminal. It only reads, checks the whole chain, and prints a fix under anything that is wrong.
