How this free Facebook Page scheduler works
Draft a Facebook Page post (text, image, video, or link), pick a publish time, and copy the draft into Postmixr after signing up. Facebook supports native scheduling via the Graph API — Postmixr uses scheduled_publish_time so posts go live without anyone touching Business Suite.
Facebook post character limit
Facebook allows up to 63,206 characters per Page post, but readability drops sharply after a few hundred characters. Use the hook in the first line, then break the rest into short paragraphs.
Why personal profiles are not supported
Meta removed third-party scheduling permissions for personal Facebook profiles years ago. Page admins are the only accounts third-party tools can publish on behalf of, and this scheduler reflects that — only the Facebook Page target is selectable.
