Music-rights reminder: Cross-posting does not transfer every Instagram music licence to Facebook. Even audio recorded by you may contain copyrighted music playing in the background. Check the rights for both platforms and review the Facebook copy after publishing.
You already filmed the Reel, edited it, wrote the caption, and picked the audio. Posting that same video to Facebook takes ten extra seconds — and puts it in front of a second audience that skews older, shares more, and often includes the exact people who never open Instagram.
Cross-posting Reels to Facebook is built into Instagram, free, and far less fiddly than re-uploading manually. This guide covers the setup, the per-post sharing options, what changes when a Reel lands on Facebook, and when you should not cross-post at all.
1. What cross-posting actually does
When you share an Instagram Reel to Facebook, Instagram publishes a copy of the video to your linked Facebook profile or Page as a Facebook Reel. The video, caption, and most settings carry over. Likes, comments, and views are counted separately on each platform — you get two independent performances from one upload, which also means twice the data about what works.
What does not carry over perfectly: some licensed music may be muted or replaced on Facebook due to different music agreements, and interactive stickers can behave differently. Always spot-check the Facebook version after posting, especially the audio. Understanding both feeds helps — our breakdown of the Reels algorithm explains what each platform rewards, and the two are not identical.
2. Link your Instagram and Facebook accounts first
Cross-posting needs your accounts connected through Meta’s Accounts Center. On Instagram, go to your profile, open the menu, then Settings → Accounts Center → Accounts, and add your Facebook profile or Page if it is not there already. If you run a creator or business account, you have likely done this during setup — but double-check, because a surprising number of people set it up years ago and the link has quietly broken since.
Choose carefully whether to link your personal profile or a Page. Reels shared to a personal profile reach friends; shared to a Page, they reach followers and can run ads later. Creators growing an audience almost always want the Page route. You can manage or remove the link from the same Accounts Center screen at any time.
3. Turn on automatic sharing
The easiest setup is automatic: every Reel you post to Instagram also goes to Facebook without you thinking about it. In Instagram settings, find the sharing options for Facebook (under Accounts Center → Sharing across profiles, menu names shift slightly between app versions) and enable automatic Reel sharing.
Automatic sharing suits creators who post daily and treat both platforms as one distribution system. It does not suit everyone — if your Facebook audience is family and your Instagram is a professional brand, auto-sharing every Reel can feel wrong. There is no shame in keeping it manual; the toggle exists per post for exactly this reason.
For per-post control, use the share sheet on the final post screen. After editing your Reel, on the screen where you write the caption, look for the Share to Facebook toggle (sometimes labeled “Also share to Facebook” or shown as a Facebook icon). Turn it on for this post only.
You can also share older Reels retroactively: open the Reel, tap the share/send icon, and choose to share or recommend it on Facebook. This is useful when an old Reel suddenly performs well and you want to give it a second life in front of a new audience. Write the caption once, well — our Reels caption formulas work on Facebook too, since the caption text carries over verbatim.
5. What changes on Facebook (check these)
Four things deserve a quick check on the Facebook copy. Audio: if Instagram used a trending licensed track, Facebook may mute or swap it — original audio you recorded yourself is always safe. Hashtags: they work on Facebook but carry less discovery weight; three to five relevant ones beat thirty. Captions and mentions: @mentions of Instagram-only accounts will not link properly on Facebook, so tag the Facebook versions where it matters.
Cover and framing: both platforms are vertical 9:16, so framing survives — but Facebook’s interface overlays sit in slightly different spots, so keep key text away from the very bottom edge. If you are building Reels from proven templates, the structure transfers cleanly; just re-verify the audio on the Facebook side before moving on.
6. When NOT to cross-post
Cross-posting everything is a strategy, but it is not always the right one. Skip it when the Reel references Instagram-specific features (“link in bio,” story polls, close-friends jokes) that will confuse Facebook viewers. Skip it when your two audiences genuinely differ — a Reel roasting corporate life might thrill Instagram followers and horrify the relatives on your Facebook.
Also skip auto-sharing for experimental content. If you are testing a new format, let it prove itself on one platform first; a flop that flops in two places just doubles the embarrassment. And never cross-post content with trending audio you have not verified on Facebook — a muted Reel is worse than no Reel.
7. Read performance on both sides
After a week of cross-posting, compare: which platform gives more views, which gives more shares, which drives profile visits? Facebook audiences tend to share practical and emotional content further, while Instagram rewards novelty and aesthetics. The same Reel can be a quiet performer on one and a hit on the other — that is the whole point of distribution.
Use the difference to plan: make more of what each audience responds to, and consider tailoring occasionally — same footage, slightly different hook text per platform. Two audiences from one shoot is efficient; two slightly tailored versions from one shoot is a content strategy.
The bottom line
Link your accounts once, decide between automatic and per-post sharing, and spot-check audio and mentions on the Facebook copy. Ten seconds of extra effort per Reel buys you a second audience, a second algorithm, and a second stream of feedback. Start with your best-performing Reels, watch which platform responds, and let the data decide how much you cross-post. Instagram’s official Help Center documents the current sharing settings, since menu names change with app updates.
Frequently asked questions
Yes, if your Instagram and Facebook accounts are connected through Meta Accounts Center and the sharing option is available. Turn on automatic Reel sharing in the sharing-across-profiles settings.
2. Do I need a Facebook Page to cross-post Reels?
You can share to a linked Facebook profile or Page, depending on the account setup and options shown. Choose the destination that matches your audience and business goals.
On the final Reel publishing screen, use the Share to Facebook or Also share to Facebook option if available. Turn it on for that post without enabling automatic sharing for every Reel.
4. Can I cross-post an old Instagram Reel?
Some Reels can be shared or recommended to Facebook after they have been published. Open the Reel and check the share menu for the available Facebook option.
5. Will likes and comments combine across Instagram and Facebook?
Performance is generally tracked separately on each platform. Compare each platform’s views, comments, shares and other available insights independently.
6. Why is the music missing on my Facebook Reel?
Music rights can differ between Instagram and Facebook, and a track licensed on one platform may be muted or unavailable on the other. Check the Facebook copy and use audio cleared for both destinations.
7. Can I cross-post Reels from a private Instagram account?
Cross-posting options depend on account type, privacy settings and the linked Facebook destination. Check the sharing controls shown in Accounts Center and consider whether the audience should be public or limited.
8. Can I choose a different Facebook caption?
Available editing options can vary by publishing route. If you need a different caption, publish or schedule the Facebook version separately and edit its copy before posting.
9. Does cross-posting hurt Instagram reach?
There is no universal rule that cross-posting reduces reach. Each platform has its own audience and ranking systems. Review your own insights and tailor the hook or caption when needed.
10. How do I stop Instagram from automatically sharing Reels to Facebook?
Open Instagram Settings → Accounts Center → Sharing across profiles, choose the relevant profile and turn off automatic Reel sharing. Menu labels can change with app updates.
