Bluesky carousel generator
Bluesky takes four images per post and shows them in a grid you tap to open. Four slides is the whole format, so this generator is set up to make four that work on their own rather than a long deck that gets cut off.

5 slides is over the limit on Bluesky (4) and X (Twitter) (4). Those posts get rejected rather than trimmed, so hide or remove some, or split the carousel across more than one post.
This carousel lives in this browser. An account keeps it.
Everything you have typed here is stored on this device only, so it is gone the moment you clear your browser or switch to your phone. With a PublishQ account it belongs to you instead:
- Your carousels are saved, so you can come back and edit them.
- The images you upload stay in your media library.
- Your logo is stored once and reused on every carousel.
- Brand name, handle, and colours stop being retyped.
- Publish straight to every social account you connect — no downloading, no second tab.
Four images and a chronological timeline
A Bluesky post holds four images. They appear as a grid and open in a viewer when tapped, so like X it is a set rather than a swipe with a fixed order.
The bigger difference is the timeline. Bluesky feeds are largely chronological, so a post is seen by the people following you around the time you post it, and it does not get resurfaced days later by a ranking system. Timing matters more here and evergreen decks matter less.
Alt text is also taken seriously on Bluesky, more than on most platforms. Slides made of text with no alt text will be called out, so write it.
Designing four slides that stand alone
With four frames there is no room for a build up. Drop the title slide and the sign off, and give all four to the actual content.
Grid tiles are cropped until someone opens them, so keep text central and large. Portrait 4:5 works well and square is the safest if you want the grid even.
If the idea genuinely needs more than four frames, post four and put the rest in a reply. That reads naturally on Bluesky in a way a truncated deck does not.
Before you export
- Build four slides and skip the cover. Every frame has to carry content.
- Write alt text for each image. Bluesky users notice when it is missing.
- Post when your followers are actually online, since the timeline is mostly chronological.
- Continue in a reply rather than trying to squeeze a long deck into four frames.

— me 👋
Hi, I'm Alexandro 👋
I left my Software Engineer role at Amazon to build tools that solve real problems — the kind big companies ignore because they read spreadsheets instead of using their own products.
I was spending over an hour daily just scheduling 2 shorts across 3 platforms — logging in, reformatting, uploading one by one. That felt broken. So I built PublishQ . Now I create 4 shorts in 3 minutes and schedule them to 4 platforms in under 30 seconds.
PublishQ is bootstrapped. No investors, no vanity metrics. I build what actually helps you — because I use it every day myself.
Thank you,
Alexandro
