CLUSTER DESKTOP-IMAGES-BATCH · 31 ENTRIES · EARLIEST ENTRY 2022-11-22

Desktop batch image tools

This cluster comprises desktop applications (Windows, macOS, and portable) that batch-compress, resize, convert, and optimize images, often offline and with privacy-focused local processing. The dated history before the index start is thin but spans 2019 to 2026 with only one entry in most months, showing no clear trend—just sporadic appearances. The traction leader is compressO-rebuild with 32 stars, followed by ND-ImgConverter (12 stars) and NanoPic (10 stars).

Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.
