PostBox

Publish finished creative work to social accounts from your Mac

Meet PostBox

PostBox is a Mac app for sending finished images and videos to social platforms through a drag-and-drop workflow. Users choose the profiles attached to a post, adjust photos or covers, and publish without opening each platform's feed. Supported destinations include Instagram, YouTube, X, LinkedIn, Threads, TikTok, Bluesky, and Dribbble.

The app supports multiple accounts, image carousels, scheduled posts, and reminders, with a view of upcoming and previous work. Its interface is available from the Mac's notch area. PostBox does not require its own service account, although publishing requires connecting the relevant social accounts and satisfying their access requirements. It is offered free for macOS 15 or later.
