Post once.
Publish everywhere.
Crossposter publishes your video to TikTok, YouTube Shorts and Bluesky in one go. Upload it once, write one caption, choose where it goes, and it’s posted to every account you’ve connected.
Get started — it’s freeLog inHow it works
Sign in with Google, then connect TikTok and YouTube with their own sign-in screens, and Bluesky with an app password. You approve each one yourself and can disconnect any of them at any time.
Pick a video from your phone or computer, write the caption and hashtags, and choose where it goes. For each platform you choose Publish, or Draft to finish it in that platform’s own app.
Crossposter shows exactly what will be sent, where, and who will be able to see it. Nothing is posted until you press Crosspost. Each post links back to you when it’s live.
Where your video goes
Post directly, or send it to your TikTok inbox as a draft to add sounds and finish in the app. You choose who can see every post, from the options TikTok allows for your account.
Vertical videos go up as Shorts on your channel, with your caption as the title and description.
Your video posted to your Bluesky account, with the caption shortened to fit Bluesky’s length limit and hashtags made clickable.
Why Crossposter
Length limits, hashtag rules and line breaks differ everywhere. Crossposter tidies your one caption to each platform’s rules, so nothing gets cut off or rejected.
Nothing is posted unless you sent it or set up an automation for it. Every TikTok post’s privacy is your choice, never pre-selected, and you can pause or disconnect anything at any time.
Some iPhone recordings (HEVC, 4K HDR) are accepted by TikTok and then silently fail. Crossposter spots them and converts them to H.264 for you, so there’s nothing to export again.
Everything works in your phone’s browser, from connecting accounts to uploading straight from your camera roll.
Questions
It keeps each video only until the platforms you picked have it, then deletes it. It only posts what you send or schedule yourself.
Only permission to publish the videos you send and to show which account is connected. Access tokens are encrypted, and disconnecting an account deletes them.
MP4 or MOV files up to 300 MB. Vertical 9:16 video works best on every platform.
Crossposter is free while it is in beta.
