2 ways to post a YouTube video on TikTok

- In TikTok, tap the plus button and upload it.
- Write a TikTok caption, then post.
With PostOnce, once
- Connect YouTube and TikTok.
- Each new Short goes to TikTok without a download.
- Your title and description become the TikTok caption.
Shorts first, longer videos when you choose
Long videos in parts
Turn on splitting and a video longer than TikTok allows posts as equal parts, in order, each captioned Part 1 of 3 and so on. A 24-minute video becomes three 8-minute parts.
Title and description
Both go into the TikTok caption, up to 2,200 characters and 5 hashtags.
TikTok's daily limit
TikTok lets apps post about 15 videos a day per creator, so a big catalog goes out over several days.
Licensed music
Shorts with your own audio post as they are. TikTok may mute songs licensed on YouTube.
Older Shorts too
Turn on existing posts to send videos you uploaded before you connected.
