Facebook and Bluesky: completely separate worlds

+ ! Bluesky has a 300-character post limit — most Facebook posts are much longer
+ ! Bluesky does not natively embed Facebook content or links
+ ! Facebook images can be attached to Bluesky posts via automation tools
+ ! Bluesky's user base is distinct from Facebook's — the same tone won't work for both

What You Need to Know
How to automate Facebook-to-Bluesky posting
IFTTT has an applet that connects Facebook Pages to Bluesky: when you publish a new Facebook page post, it creates a Bluesky post with the content.
Dlvr.it offers similar functionality with more control over formatting.
Buffer now supports Bluesky natively, so you can schedule and crosspost from a single dashboard if you're already using Buffer for Facebook.
For text-only Facebook posts, the automation works cleanly within the 300-character limit.
For longer posts, the tool cuts off the text — worth editing the Bluesky draft before it goes live.
Adapting Facebook content for Bluesky's community
Bluesky's current audience is smaller and more curated than Facebook's — tech-adjacent, interested in open protocols, skeptical of corporate social media.
Content that does well on Facebook (inspirational quotes, personal life updates, broad community announcements) doesn't tend to land the same way on Bluesky.
Direct, substantive posts perform better.
Bluesky users also notice and dislike cross-posted content that looks automated or generic.
If you're posting the same thing everywhere unchanged, the Bluesky community will call it out.

PostOnce connects your Facebook page to Bluesky and publishes adapted posts automatically — formatted to fit within 300 characters and written in the direct style that Bluesky users respond to.

Direct answer
Can PostOnce automatically post from Facebook to Bluesky?
Yes, PostOnce can automatically post eligible Facebook Reels to Bluesky with a reusable crossposting workflow. This is crossposting automation: you publish on Facebook, PostOnce watches for eligible Facebook Reels, and Bluesky receives its own native post instead of a copied link preview.
Content types
Primary wording plus related formats
Facebook source formats
This workflow leads with Facebook Reels, and also covers related Facebook formats:
Bluesky destination formats
The destination focus is Bluesky, while also covering related Bluesky surfaces:
Manual sharing
The manual route usually means sharing a link, sending to a Story, making a Feed post, or downloading the media and uploading it again.
- Link previews send traffic back to Facebook.
- Watermarks or source branding can hurt trust.
- Repeated downloads make daily posting hard to scale.
- Formats and captions often need cleanup.
Automatic workflow
PostOnce turns the same workflow into a repeatable rule: source account, destination account, filters, and automatic publishing.
- Connect Facebook as the source.
- Connect Bluesky as the destination.
- Choose which posts should crosspost.
- Let PostOnce publish future matches automatically.
Alternatives and limits
IFTTT-style automations and native share buttons can be useful, but they often create status updates, links, or previews instead of native destination posts.
- Manual sharing is fine for one-off posts.
- Generic repurposing tools may require export first.
- Platform API limits still control what can publish.
- Music rights do not automatically transfer.
What gets adapted from Facebook to Bluesky
Captions
Long captions may need shortening for Bluesky.
Hashtags
Bluesky: Hashtags are clickable but not algorithmically weighted.
Aspect ratio
Both prefer 16:9 video.
Destination format
Eligible media publishes as a native Bluesky upload.
Watermark and metadata
PostOnce prepares media for the destination instead of reposting a link card.
Music and audio rights
Only reuse audio you have rights to publish on both platforms.
New posts and existing content
For new posts, PostOnce can watch your Facebook source and publish eligible Facebook Reels to Bluesky after the workflow is created.
For existing or backlog content, use PostOnce to refill a workflow deliberately instead of dumping months of posts at once. Scheduled batches keep the destination account active without overwhelming followers.
If a video is longer than Bluesky's destination limit, it needs trimming or review before publishing. Bluesky supports videos up to 1 minutes.
