PostellumSchedule Instagram posts, Reels and Stories — free
Write the caption once, add photos or a video, pick a time. Postellum publishes to your professional Instagram account and, in the same go, to Facebook, TikTok, Threads and the rest of your networks — each in its own format.
What Postellum publishes to Instagram
- Feed posts: one photo or a carousel of up to 10 slides
- Reels: one vertical video up to 15 minutes with a caption
- Stories: one photo or a video up to 60 seconds
- Your caption with hashtags, a signature and default hashtags you set once
Instagram limits Postellum follows
| What | Limit |
|---|---|
| Caption | 2,200 characters |
| Hashtags | up to 30 |
| Carousel | up to 10 photos or videos |
| Photo proportions | 4:5 to 1.91:1 |
When a post is longer than a platform allows, Postellum shortens it at a sentence or word boundary for that platform only and shows the result in the preview.
How to connect Instagram
- Switch your Instagram to a professional (Business or Creator) account — Instagram allows publishing through apps only for those.
- In Postellum, open Platforms → Instagram and sign in with Instagram. Postellum never sees your password.
- Write a post, choose Post, Reels or Story for Instagram, and publish now or at a set time.
Tips for Instagram
- Instagram requires a photo or a video in every post — the preview tells you before you publish if one is missing.
- Postellum center-crops photos that fall outside 4:5…1.91:1, so a vertical photo for TikTok can still become a neat Instagram post.
- Links in captions aren't clickable on Instagram. Put the link on networks that show it as a card, and “link in bio” here.

Questions
Can Postellum delete an Instagram post?
No — Instagram doesn't allow deleting posts through apps. Delete it in the Instagram app; Postellum removes it from your other networks.
Do I need a Facebook Page?
No. A professional Instagram account is enough.
