What You Need to Know
How creators crosspost TikToks to LinkedIn today
The manual process: download the TikTok without the watermark (SnapTik, SSSTik, or saving before publish), upload to LinkedIn as a native video, rewrite the caption as a professional narrative rather than a hook-first sentence, and add a few relevant hashtags from LinkedIn's professional categories.
Make your LinkedIn video look native
LinkedIn is not a place where TikTok culture translates.
Three adjustments make a TikTok feel like it belongs there.
Skip the manual work with PostOnce
PostOnce connects TikTok and LinkedIn and automates the crosspost as a native video upload.
When you post a TikTok, PostOnce pulls the watermark-free video and publishes it to your LinkedIn profile or company page as a native video — not a link, not a preview.
The full video, in the LinkedIn feed.
