Dinky
Dinky vs Optimage
Both keep files on your Mac. Optimage is paid with a heavier install; Dinky is MIT-licensed, free, and stays tiny.
Choose Optimage if it already matches your workflow
When your team is bought into Optimage’s tooling, licensing, and feature mix and you do not need a change, staying put is reasonable.
Choose Dinky if you want free, open source, and tiny
When you want inspectable code, zero purchase, codec conversion, video and PDF in one drop zone, watch folders, and to keep install weight down.
