Text and local files stay in your browser. Public image and video URLs load from their hosts. ## How to use it 1. Write your post and choose a format. 1. Add your account details and media through Post details. 1. Compare the full page and post card at phone, tablet, or desktop widths. ## What to check on YouTube Check whether the title still explains the video when it wraps. Use the watch page for long videos and Short for vertical footage. A title and thumbnail need to work together before playback. Check the uploaded video proportions and the channel name below it. ## 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 They do not publish anything, fetch a live account, or certify that a format can be published through OpenPost.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. ## Keep making [X post preview](https://openpo.st/tools/x-post-preview)[Bluesky post preview](https://openpo.st/tools/bluesky-post-preview)[Mastodon post preview](https://openpo.st/tools/mastodon-post-preview)[Pixelfed post preview](https://openpo.st/tools/pixelfed-post-preview)
