How to post to Instagram and TikTok at the same time
Upload your original video file to both, through each app's own upload screen or with a tool like deploy.social that connects both accounts at once. The one shortcut that skips this, TikTok's share button, comes with a catch: it stamps TikTok's watermark on the Instagram side.
Three ways to do it
TikTok's own share button
Share straight from TikTok to Instagram and the video arrives with TikTok's watermark on it, whether you post it as a Reel, a Story or a feed post. Instagram has said it doesn't recommend Reels carrying another app's logo, so a video shared this way reaches fewer people.
Download, then upload by hand, twice
A file saved out of TikTok keeps the watermark baked in, so this ends the same way as sharing. Only your original file, saved from your camera or editor rather than from TikTok, is watermark-free. Uploading that to each app separately works, it just means the caption, cover and settings happen twice.
A tool that connects both accounts
Connect Instagram and TikTok once, upload your original file, and it posts to both through each platform's own posting API, with no watermark because nothing is downloaded from TikTok in the first place. Instagram still needs a Business or Creator account for any tool to reach it; a personal account only works from inside the Instagram app.
What each method gets you
| Method | Watermark-free? | Posts to both at once? |
|---|---|---|
| TikTok's share button | No | No, only after the TikTok is already live |
| Download, then upload by hand | No | No, one platform at a time |
| Your original file, uploaded once | Yes | Yes, by hand on each app or through a tool like Deploy |
What a scheduling tool actually needs, to post for you
TikTok reviews every app that wants to post publicly on someone's behalf before granting that access; an app that hasn't passed the review can only post privately, visible to the account holder alone. Instagram's own requirement sits on the account instead of the app: Business and Creator accounts are the only ones any outside tool, Deploy included, can publish to.
How deploy.social handles it
Deploy connects to Instagram and TikTok through each one's own posting API, passed TikTok's Content Posting review, and posts your original upload to both at once, with one caption that's checked against each platform's own limit first. Nothing is ever pulled from TikTok itself, so nothing Deploy posts carries its watermark.
Questions
Can you post to Instagram and TikTok at the same time?
Yes, by uploading your original video file to both, either by hand on each app or through a tool that connects both accounts, like deploy.social.
Does sharing a TikTok to Instagram add a watermark?
Yes. TikTok's share button puts its watermark on the video, whether you share it to Instagram as a Reel, a Story or a feed post.
Do I need a business account to post to Instagram with a tool?
Yes, a Business or Creator account. Instagram only lets outside tools, deploy.social included, publish to those two account types.
Does TikTok let any posting tool publish publicly?
Only once that tool has passed TikTok's own review. Before that, posts through its API can only go out privately. deploy.social's review was approved in August 2026.
Try it with your next video.
Connect Instagram and TikTok, upload your file once, and Deploy posts it to both without touching TikTok's watermark. 5 videos a month are free.
