Post preview
Social network designs can change.
Scroll the preview sideways when the selected screen is wider than this workspace. All names, counts, and surrounding posts are illustrative.
Text and local files stay in your browser. Public image and video URLs load from their hosts.
How to use it
- Write your post and choose a format.
- Add your account details and media through Post details.
- Compare the full page and post card at phone, tablet, or desktop widths.
What to check on Mastodon
Write a content warning that explains what is behind it. Expand the warning in the preview and check the revealed text.
Keep the complete federated handle recognizable. Attachment and poll limits depend on the server where you publish.
Native layout and publishing availability
These previews illustrate native network layouts. They do not publish anything, fetch a live account, or certify that a format can be published through OpenPost. Network apps, account types, and server settings can change the final appearance and limits.
Common questions
Do I need an account?
No. You can edit and preview a post without signing in.
Can I preview the whole page?
Yes. Choose Full page for the surrounding feed, channel, or watch page. Choose Post card to focus on the content itself.
Will my files upload?
Local files use temporary browser URLs and are not uploaded. Closing or refreshing the page clears your draft.
