How to connect Instagram to YouTube in 3 steps
Every Reel gets a second life in YouTube search.
Connect Instagram
Use the Business or Creator account your Reels come from.
Connect YouTube
Pick the channel that should get each Short.
Turn on the workflow
New Reels post as Shorts, now or in a slot you set.
Link your profiles, or post your Reels
A link, or a manual upload
- Adding your Instagram to YouTube only shows a link.
- To post a Reel, save it, then upload it in the YouTube app.
- Write a title and description for every Short.
With PostOnce, once
- Connect Instagram and YouTube.
- Each new Reel becomes a Short, 7 in 10 within 30 minutes.
- Your caption's first line becomes the Short's title.
Post Instagram Reels as YouTube Shorts
Title and description
The first line of your caption becomes the title, up to YouTube's 100 characters. The full caption becomes the description.
Photos stay on Instagram
YouTube only takes video, so photo and carousel posts are skipped.
Licensed music
Reels with your own audio post as they are. Reels with licensed songs post too, but YouTube may mute or remove them later.
Older Reels too
Turn on existing posts to send your back catalog. YouTube caps daily uploads per channel, so big catalogs take a few days.
Account type
Instagram Business or Creator, plus a YouTube channel.
Questions about Instagram and YouTube
How do I add my Instagram link to my YouTube channel?
In YouTube Studio, go to Customization and add your Instagram under Links. That shows a link on your channel; it doesn't copy any Reels.
Can I post the same video on Instagram and YouTube?
Yes. PostOnce posts through YouTube's official upload API, like any scheduler. In a check of 40 YouTube channels before and after crossposting, views showed no consistent drop.
How do I post on Instagram and YouTube at the same time?
Post your Reel on Instagram and PostOnce sends it to YouTube straight away. Of 1,280 Reels PostOnce sent right away in the last 30 days, half were live as Shorts within about 5 minutes.
Are Instagram Reels and YouTube Shorts the same format?
Both are vertical videos, and Shorts can run up to 3 minutes, so most Reels fit as they are.
Do photos and carousels go to YouTube?
No. YouTube only accepts video, so PostOnce sends your Reels and skips photo posts.
Can I move my old Reels to YouTube?
Yes. Turn on existing posts. YouTube limits how many videos a channel can upload a day, so send a large catalog over a few days.
What happens to music in my Reels?
Your own audio posts as it is. Songs licensed inside Instagram don't bring their rights to YouTube, so YouTube may mute or remove those Shorts.
Do I need an Instagram Business account?
A Business or Creator account, plus a YouTube channel. Instagram doesn't let apps read personal accounts.
