- Tap the Instagram toggle, or pick both in Meta Business Suite.

- Publish on your Page as usual.
- Instagram gets its own caption, Stories too.
Facebook Reels stay Reels on Instagram
Albums become carousels
A Page album posts as an Instagram carousel; past 10 items, the first 10 go.
Page Stories reach your Instagram Story
Switch on Include Stories and your Page Stories post as Instagram Stories, not feed posts.
Captions written for Instagram
Rewrite caption with AI opens with a short hook, keeps up to 5 hashtags and never writes “click the link”. Without it, captions stop at 2,200 characters.
Text and link shares stay on Facebook
Instagram needs a photo or video, so text-only posts and bare link shares aren't sent.
Trial Reels, if you want them
Publish as Trial Reels tests each Reel with non-followers first; photos and albums skip that account.
Facebook to Instagram sharing questions
Do Facebook posts automatically post to Instagram?
Not by default. From a profile linked in Accounts Center, you can turn on sharing for future Facebook posts. For a Page, PostOnce posts each new Reel, photo and album through Instagram's official posting API.
Why didn't my Facebook post share to Instagram?
Instagram needs a photo or video, so text-only posts and posts that only share a link don't go. PostOnce also needs an Instagram Business or Creator account.
Can I share a Facebook post to Instagram after posting?
Meta's toggle works as you post. PostOnce's existing-posts switch sends Page posts you've already published, on paid plans and the trial.
Can I share a Facebook post to my Instagram Story?
Yes. With Include Stories on, Page Stories post as Instagram Stories. Post everything as Stories sends single photos and videos up to 60 seconds to your Story instead of the feed; albums and longer videos then skip that account.
Can I share Facebook Reels to Instagram?
Yes. Each new Page Reel posts to Instagram as a Reel, up to 15 minutes, caption included.
Can I post from a personal Facebook profile?
Not with PostOnce: Facebook lets apps read Pages only. From a profile, use Meta's own sharing in Accounts Center.
Is crossposting from Facebook to Instagram a good idea?
Yes, for posts that suit Instagram. PostOnce publishes through Instagram's official posting API like any scheduler, and How2Rizz grew to about 10k Instagram followers this way. New or quiet accounts start slow either way, so warm them up.
