# Connect YouTube to Facebook

> Connect your YouTube channel as the source and your Facebook Page as a destination in Post Once. From then on, the Shorts and longer videos you upload to YouTube go to Facebook on their own, with your caption.

## Before you start

- A YouTube channel. Any channel you can sign in to works, monetized or not.
- A Facebook Page you manage. Facebook only lets apps post to Pages, not personal profiles.
- A Post Once account. The free plan includes 10 reposts, with no card needed.

## How to connect YouTube to Facebook

1. Create a free account at [app.postonce.com](https://app.postonce.com/signup). After two short intro screens, Post Once asks where you post.
2. Under **Where do you post first?**, pick **YouTube** and press **Continue**.

3. Under **Where else should it land?**, pick **Facebook**. Add any other apps, or a backup, then press **Continue**.
4. On **Connect your accounts.**, press **Connect** on the YouTube row. Sign in with the Google account that owns your channel and allow access.

5. Press **Connect** on the Facebook row. Sign in with Facebook. In the permissions dialog, make sure the Page you want is selected. Back in Post Once, pick it in the **Post to Page** list on the Facebook row. With only one Page, it is picked for you. Nothing is posted to Facebook until a Page is picked.
6. When both rows say **Connected**, press **Go to dashboard**.

From then on, keep posting on YouTube as usual. Post Once checks it about every five minutes and reposts each new post to Facebook.

## Already using Post Once?

If YouTube is already the source of your bridge, open **Bridge** and press **Connect** next to Facebook in the **Destinations** card, or press **Add destination** on the dashboard. Then pick the Page in the **Post to Page** list.

If your bridge reads from another account, add a second bridge with YouTube as its source from the bridge switcher. Free and Solo include 1 bridge, Studio 3 and Agency as many as you need. See [bridges](https://postonce.com/help/bridges).

## What each YouTube post becomes on Facebook

| On YouTube | On Facebook |
|---|---|
| A Short | A Reel if it runs up to 90 seconds, otherwise a Page video. |
| A video over 3 minutes, or a landscape one | A Page video, up to 2 hours, titled with the first line of your caption. |

A skipped post shows the reason on your dashboard and still goes to your other destinations. See [long videos](https://postonce.com/help/long-videos) for how Post Once tells short from long.

## How your caption carries over

The video's description becomes the caption. A video with no description uses its title instead. Private and unlisted videos are not picked up, and neither are community posts.

Facebook gets the caption up to 2,200 characters. A long video is titled with the first line of the caption.

## Choose what goes to Facebook

On the **Bridge** page, the Facebook row has two settings.

- **What to post** has one switch here, **Videos**, since videos are all that go from YouTube to Facebook. Turning it off pauses Facebook.
- **Rewrite caption** changes the caption for Facebook only: **Remove comment, DM and link in bio prompts**, **Remove hashtags and mentions**, **Rewrite with AI to suit Facebook**, and **Add your own text** at the start or end. Each one is off until you turn it on.

## Check that it works

Post something on YouTube as usual. Within about five minutes it shows up under **Your posts** on the dashboard (press **Check now** to look straight away), then goes to Facebook. Each post shows where it went, what was skipped and why.

If a repost fails, Post Once tries again up to 5 times over about half an hour. If it still fails, you get an email, and **Retry** sends it again to just the accounts it missed. See [a post did not repost](https://postonce.com/help/post-not-reposted).

Only posts published after you connect are reposted on their own. Older ones are listed in [Your posts](https://postonce.com/help/your-posts), where you can send any of them by hand.

## Frequently asked questions

### Is it free to repost YouTube to Facebook?

Every account gets 10 free reposts, with no card and no watermark. One repost is one post sent to all your destinations, so it counts once however many apps it goes to. After that, paid plans start at $9 a month. See [pricing](https://postonce.com/pricing).

### How fast do YouTube posts reach Facebook?

Post Once checks YouTube about every five minutes, then reposts straight away. Long videos take a few more minutes to fetch and upload.

### What are the limits of reposting from YouTube to Facebook?

Post Once sends at most 50 posts per Page per day. Extra posts wait and go out once the limit resets. Videos can run up to 2 hours, at up to 4K.

### Why was my 4K video reposted at 1080p?

Post Once takes the best version that every destination accepts, and that tops out at 1080p. A 4K upload is reposted at 1080p.

### Can Post Once post to my personal Facebook profile?

No. Facebook only allows apps to post to Pages. Pick a Page you manage.

### I get "No Facebook Page chosen". What do I do?

Facebook is connected but no Page is picked yet. Open Bridge and choose one in the Post to Page list on the Facebook row. New posts then go to that Page.
