Explorer thumbnails for 326 file types Windows can't read, plus a right-click image toolkit.
SageThumbs 2K is a modern, crash-isolated Windows 11 shell extension written in Rust that rebuilds the classic SageThumbs. It gives File Explorer thumbnails for 326 file types Windows can't preview on its own — camera RAW, HEIC/AVIF, Photoshop, DjVu, ebooks and comics, video frames, 3D-print files and a long tail of obscure formats — plus a right-click image toolkit (convert, resize, rotate, OCR, color picker, metadata strip, combine-to-PDF/CBZ) and a console/AI CLI. Free for personal use.
HEIC and AVIF thumbnails keep their declared colors. Files that pair Display-P3
primaries with a non-sRGB transfer curve are no longer forced through an incompatible
Display-P3 profile, which could produce a visible color cast. Embedded ICC profiles and
standard iPhone Display-P3 images continue through the normal color-managed path.
