Dinky
Dinky vs CloudConvert
CloudConvert converts files in the browser and via API—great breadth, cloud processing. Dinky is a native Mac drop zone so stills, MP4, audio, and PDF jobs stay on your disk with open-source code.
Choose CloudConvert for cloud/API breadth
When you need rare format pairs, team quotas, or server-side conversion—and accept uploads for that convenience.
Choose Dinky for local-only compression
When NDAs, client work, or habit say “never leave this Mac”—batch, watch folders, Finder actions, and MIT-licensed internals without a browser round trip.

CloudConvert wins on catalog size; Dinky wins when the asset never leaves your Mac—same batch and watch-folder flow for stills, MP4, audio, and PDFs.
