Convertible

A fast, native Mac utility for converting and compressing files without sending anything to the cloud. Convertible converts images, video, audio, and PDFs entirely on-device, lossless when possible. Supports hard-to-open formats (MKV, WebM, HEIC), and can shrink files to hit specific size limits in one click. Integrates with Shortcuts via App Intents. Build conversion into your own automations and run it from Finder's right-click menu, Spotlight, a hotkey, or a schedule. Privacy-first, no telemetry, one-time purchase.
