Why Socialync for Instagram to TikTok
Upload once, post to both
Drop a video into Socialync. We publish to Instagram and TikTok at the same time, so you can i cross post from instagram to tiktok without copy-paste.
Both support 9:16 vertical video
Instagram Reels and TikTok both prefer 1080×1920 vertical. The same video file works on both, no aspect ratio changes needed.
Different caption styles per platform
Instagram captions can run 3-5 sentences with storytelling. TikTok hooks live in the first 1-2 lines. Customize each in Socialync without copy-pasting.
Trusted by creators and businesses
Join thousands of people who stopped manually reposting.
The multi-platform posting is seamless. My content reaches 3x more people with zero extra effort.
Simple dashboard, easy sign-up, and the scheduling is so nice. If I make 10 videos in one day I can schedule them to all platforms weeks in advance. Goated!
I built this because I was burning out posting manually. Now I post in 3 minutes instead of 45.

Frequently asked questions
Can I cross post from Instagram to TikTok?
Yes. Socialync publishes to both Instagram and TikTok simultaneously from one upload. You can customize captions and hashtags per platform, and either post instantly or schedule for each platform peak time.
How do I share an Instagram Reel to TikTok without the watermark?
Upload your original source video to Socialync. Re-downloading a posted Reel from Instagram strips quality and adds an Instagram watermark that TikTok also down-ranks. One clean source file means both platforms get the best version.
Can I customize captions and hashtags per platform?
Yes. Each platform has its own caption and hashtag fields in Socialync. Instagram gets longer storytelling captions with niche tags; TikTok gets short hook-driven copy with trending tags.
