How to preview a Bluesky post
Bluesky posts are short, 300 characters each, so threads are common. The preview shows every post in the chain with its avatar, text and image grid, which makes it easy to spot a post that ends mid-thought or an image grid that crops the wrong way.
Write the post
Paste your text; each Bluesky post is limited to 300 characters.
Add images or a thread
Attach up to four images, or add follow-up posts.
Check and download
Review the chain in light or dark mode and save a PNG.
SimplePost recreates a Bluesky-style post. It is not affiliated with Bluesky, and small differences can appear when Bluesky updates its app.
