The story of ThumbsPlus and WebP is one of adaptation. Recent efforts to relaunch and update the software have focused on bridging these modern gaps. As newer versions and service packs were released, the goal was to integrate the necessary libraries to handle WebP's unique encoding.

Performance is slow with WebP folders
- Storage costs: A 10,000-image database at 10MB per JPEG = 100GB. The same as WebP at 80% quality = ~25GB. ThumbsPlus lets you manage that compression visually.
- Metadata preservation: ThumbsPlus retains EXIF, IPTC, and XMP data during WebP conversion. Many converters strip this data; ThumbsPlus does not.
- Search speed: Because WebP files are smaller, ThumbsPlus loads thumbnails faster from a network drive than JPEGs of equivalent quality.
