Why cross-post from TikTok to Facebook?
Facebook Reels reaches an audience that rarely overlaps with TikTok—primarily users aged 25-55. Cross-posting lets you double your content's reach without creating new videos. Facebook also supports longer captions (8,000 chars) and works well with community-building engagement.

How to cross-post from TikTok to Facebook
- 1
Download your TikTok without watermark
Facebook does not aggressively penalize watermarks, but clean videos perform better and look more professional.
- 2
Rewrite your caption for Facebook's audience
Facebook's audience skews older and prefers conversational, community-driven content. Rewrite TikTok's Gen-Z slang into approachable language.
- 3
Reduce hashtags dramatically
TikTok uses up to 10 hashtags. Facebook only supports 3 effectively and they matter much less for discovery. Use 1-3 relevant hashtags.
- 4
Upload as a Facebook Reel
Post as a Reel for maximum algorithmic reach. Facebook Reels get significantly more exposure than standard video posts.
- 5
Add a discussion-starting question
Facebook rewards comments above all other engagement. End your caption with an open-ended question to spark conversation.
Formatting tips for TikTok to Facebook
Facebook supports vertical and landscape
TikTok is strictly 9:16. Facebook Reels work best in 9:16 but also support 16:9 and 1:1. No reformatting needed for vertical TikToks.
Simplify your hashtag strategy
Drop from TikTok's 10 hashtags to just 1-3 on Facebook. Hashtags matter less here—focus on caption quality instead.
Use longer, conversational captions
Facebook supports 8,000 characters (vs TikTok's 2,200). Use this space to tell stories and encourage discussion.
Common mistakes to avoid
Using Gen-Z slang on Facebook
Facebook's audience is older. Rewrite trendy TikTok language into conversational, universally understandable captions.
Over-hashtagging on Facebook
Facebook posts with too many hashtags look spammy. Stick to 1-3 relevant hashtags maximum.
Ignoring Facebook's comment-driven algorithm
Facebook prioritizes comments over views. End every caption with a question or call-to-comment to boost reach.
Pro Tip
Post your TikTok to a Facebook Page, not just your personal profile. Pages get access to Reels analytics, monetization features, and much wider distribution through the Reels feed.
Frequently asked questions
Can I share TikTok videos directly to Facebook?
TikTok has a built-in share-to-Facebook button, but it shares as a link, not a native video. For best results, download the video and upload natively to Facebook as a Reel.
What video format does Facebook Reels support?
Facebook Reels support 9:16 vertical video (same as TikTok), 1:1, and 4:5 formats. Videos can be 10-240 seconds with a max file size of 1GB.
Do Facebook Reels get more reach than regular posts?
Yes. Facebook is actively promoting Reels in the feed and dedicating a separate Reels tab. Reels typically get 2-5x more organic reach than standard video posts.
