How to Post a Facebook Reel from the Sparkforge Social Planner

By Sparkforge Support Team ·Last reviewed May 3, 2026

In the Social Planner, create a new post on a Facebook Page, switch to the Reels tab, attach a vertical video (3-90 sec, MP4/MOV/WEBM, up to 1 GB), and schedule. Reels work for Pages only, not Groups.

Short-form video keeps growing as the dominant format on social. Sparkforge's Social Planner now publishes Facebook Reels directly, so you can plan and schedule them alongside your other posts.
