Part 1: How to Share Facebook Posts to Instagram: Step-by-Step Guide

1. From Facebook App to Instagram (Mobile Users)

Sharing from your phone is the quickest way to get a Facebook post onto Instagram, especially for fresh posts you’ve just whipped up. It’s perfect for casual users or influencers keeping their feeds in sync, per Facebook’s help guide.

Steps:

Step 1: Open the Facebook app on your iPhone or Android.

Step 2: Create a new post or find a public post you’ve shared (public posts share best).

Step 3: Tap the “Share” button and pick “Instagram” (link your accounts in Settings > Accounts Center if it’s your first time).

Step 4: Edit the post in Instagram—add filters, tweak the caption, throw in hashtags—and hit “Post.”

Helpful tips: To avoid issues, make sure your Facebook and Instagram accounts are both linked within Accounts Center. Go ahead and share posts publicly, though since Stories and private posts wouldn't work. If the Instagram option does not show up, check to see that your accounts are properly linked or update your app.

I had fun sharing that goofy cat meme from Facebook on Instagram through my phone for good measure, and, after a few quick touches like applying a filter and some hashtagging, it was up on the Insta feed in seconds. It's super easy, except I messed up my first time because the accounts weren't linked- so don't skip this!

2. From Desktop/Laptop via Meta Business Suite

For laptop users, Meta Business Suite is your go-to for cross-posting, especially if you’re managing a professional page or scheduling content, per SocialBee and Hook Agency.

Steps:

Step 1: Log into your account at business.facebook.com.

Step 2: Connect your Instagram account so that you can access it from the Business Suite dashboard under "Accounts" > "Instagram Accounts."

Step 3: Either create a new post or edit an existing one, then toggle the “Share to Instagram” switch.

Step 4: This takes you to the Instagram post. Crop your image, change the caption if you want, and hit Publish or Schedule.

Tips: Switch your Instagram to a Professional account (Creator or Business) for full Meta Business Suite features. Schedule posts to hit both platforms at peak times for max engagement. If the Instagram toggle’s missing, ensure your accounts are linked and Instagram is in Professional mode.

I used Meta Business Suite to share a promo post for my side hustle from my laptop, and it landed perfectly on both platforms with one click. Setting up the account linkage took a minute, but it’s a lifesaver for managing posts without touching my phone.

3. Types of Content and What Can Be Shared

Not every Facebook post plays nice with Instagram, so knowing what works saves you headaches, per Marko Polo.

• Shareable: Public posts with photos, text, or short videos (under 60 seconds for Instagram Reels), single images, or carousel posts.

• Not Shareable: Stories, private posts, albums, marketplace listings, or shared posts from other pages.

• Workaround: For unshareable content like long videos or Stories, download the content and manually upload it to Instagram as a Reel, post, or Story.

Tips: Trim videos to 60 seconds for Reels to fit Instagram’s vibe. Add Instagram-specific hashtags (#InstaVibes, #PhotoOfTheDay) to boost reach. Save your post as a draft in Meta Business Suite to tweak later if needed.

I tried sharing a long Facebook video but hit a wall since it wouldn’t cross-post directly. Downloading it and posting as a Reel with some hashtags got way more likes than the original—definitely worth the extra step!

It lets you grab any public Facebook video and upload it manually to Instagram as a Reel or post, watermark-free, per Toolsmart. No ads, no signup, just a quick, clean way to repurpose videos.

When direct sharing flops—like for long videos, Stories, or third-party posts—Toolsmart’s Free Facebook Video Downloader saves the day by letting you download and repost to Instagram, per Toolsmart. It’s perfect for turning Facebook videos into Instagram Reels or Stories with minimal effort.

Step 3: Paste the URL into Toolsmart’s downloader and click “Download.”

Tips: Ensure the video is public for easy downloading—private posts won’t work. Trim videos to 60 seconds for Instagram Reels using Instagram’s editor. Add a catchy caption to boost engagement.

I used Toolsmart to grab a public workout video from a Facebook fitness page and turned it into an Instagram Reel with some upbeat music. It downloaded in seconds, looked crisp, and got tons of likes. No signup or ads made it a breeze compared to fiddling with screen recordings.
