Thumbsplus Webp Review

No native support. These versions were released before WebP gained traction. You cannot view thumbnails for WebP files, nor can you convert to/from WebP within the software.

Cause: ThumbsPlus is likely decoding the WebP to bitmap for every thumbnail repaint. Fix: Generate thumbnails once, then lock them. Right-click the folder > Properties > Thumbnails > Lock thumbnails. This prevents recalculating. thumbsplus webp

db_path = "C:\ThumbsPlus\Catalog.tpd" webp_folder = "D:\ImageArchive" proxy_folder = "D:\ThumbsPlus_Proxies" No native support

For users clinging to the classic ThumbsPlus v9 (still beloved for its speed on legacy hardware), you are not entirely out of luck. You cannot natively load WebP, but you can use a workaround: External Viewers. thumbsplus webp
