Bluesky post preview

A Bluesky post shows the whole text up to 300 characters with no truncation, and a single image displays at the ratio you uploaded unless it is taller than 1:2. PostDecks renders that layout, the name and domain handle, the post, up to 10 photos as a grid or a swipe carousel, and the reply, repost, and like row, so you can see how it reads before you post.

Before you publish

Bluesky shows your full post, so check the image crop and how the whole thing reads. Export a PDF or PNG when you are happy. It all runs in your browser, with nothing uploaded.

Frequently asked questions

What size are Bluesky images?
Bluesky shows a single image at the ratio you upload, unless it is taller than 1:2: the feed trims those, which catches a full-height phone screenshot. 1080 by 1350, a 4:5 ratio, works well in the feed, and square is a safe alternative. PostDecks lets you switch between them before posting.
How many images can a Bluesky post have?
Up to 10, since June 2026. Two to four show as a grid, and five or more as a swipe carousel. PostDecks previews both.
How long can a Bluesky post be?
A Bluesky post can be up to 300 characters and shows in full, with no more link. PostDecks counts your characters as you type.
Is it free?
Yes, preview and export are free with no account, and your content never leaves your browser. Sending it to a client to approve is free too, with a free account.
