WordPress Crosspost posts to your WordPress.com (or self-hosted <a href="http://jetpack.me/" rel="nofollow ugc">JetPack</a>-enabled) blog of your choice whenever you hit the “Publish” (or “Save Draft”) button. It can import your reblogs and other posts on WordPress.com. It even downloads the media attachments in your WordPress.com posts and saves them in your self-hosted WordPress Media Library.
Transform your self-hosted WordPress website into a back-end for your WordPress.com-hosted website. Create original posts on your local computer, but publish them to WordPress.com. Import your WordPress.com reblogs. <a href="https://maymay.net/blog/2014/02/17/keep-a-running-backup-of-your-tumblr-reblogs-with-tumblr-crosspostr/" rel="nofollow ugc">Always have a portable copy (a running copy) of your entire WordPress.com blog</a>.
This plugin uses <a href="http://developer.wordpress.com/docs/api/" rel="nofollow ugc">WordPress.com’s REST API</a> to keep posts in sync; when you edit your WordPress post, it updates your crossposted post. Private WordPress posts stay private on the remote site, deleting a post from WordPress that you’ve previously cross-posted deletes it from the remote site, too, and so on. Scheduling a WordPress post to be published any time in the future will add it to the remote site’s future publication schedule, too. See the <a href="https://wordpress.org/plugins/wp-crosspost/other_notes/" rel="ugc">Other Notes</a> page for a complete listing of features.
WP-Crosspost is very lightweight. It just requires you to connect to your WordPress.com account from the plugin options screen. After that, you’re ready to cross-post!
Other options and features enable tweaking additional metadata from your WordPress entry (notably categories and tags) to the remote site, switching comments and pingbacks on or off, and more.
WP-Crosspost transforms your self-hosted WordPress website into a back-end for your WordPress.com-hosted website. Create your posts locally on your own computer’s WordPress, but publish to WordPress.com’s servers. This means you’ll always have a portable copy of your entire blog, and you can stop worrying about whether your backups are up to date. Create new content locally, then move them to the server automatically, instead of the other way around!

Full feature list
WP-Crosspost turns your self-hosted WordPress blog into the back-end of one of your WordPress.com sites. Crossposting between self-hosted WordPress blogs is theoretically supported (but untested) if you have <a href="https://jetpack.me" rel="nofollow ugc">JetPack</a> installed and enabled on the remote self-hosted WordPress blog.
You can crosspost (push):
<ul>
<li>Posts (of <a href="https://codex.wordpress.org/Post_Types" rel="nofollow ugc">any type</a>, including <a href="https://codex.wordpress.org/Pages" rel="nofollow ugc">Pages</a> and custom post types). Pushed data includes the post’s:
<ul>
<li>date</li>
<li>title</li>
<li>status and visibility settings (including the <a href="https://codex.wordpress.org/Using_Password_Protection" rel="nofollow ugc">post password</a> if set and whether or not the post is currently in the trash)</li>
<li>format</li>
<li>tags</li>
<li>categories</li>
<li>slug</li>
<li>whether comments are on or off</li>
<li>whether <a href="https://codex.wordpress.org/Glossary#Pingback" rel="nofollow ugc">pingbacks</a> are on or off</li>
<li>whether the post is <a href="https://codex.wordpress.org/Sticky_Posts" rel="nofollow ugc">sticky</a></li>
<li>featured image,</li>
<li>content</li>
<li><a href="https://codex.wordpress.org/Excerpt" rel="nofollow ugc">excerpt</a>,</li>
<li>image attachments, along with the actual image media file itself</li>
</ul>
</li>
</ul>
Some notes on crossposting (push-posting):
<ul>
<li>If you update a post on the remote site (such as on WordPress.com), the change will not be pulled back automatically, so always prefer to use your self-hosted WordPress blog to make changes.</li>
<li>When you upload a file to your Media Library, it will not be crossposted to the remote site’s Media Library until and unless you attach it to a post and save the post.</li>
<li>The URLs of images and other media files will be automatically rewritten to reference the remote site’s copy, so always use local URLs in your posts. (Let the plugin handle media URLs itself.)</li>
</ul>
When sync’ing is enabled, you will import (pull):
<ul>
<li>Posts (of any type, including pages and custom post types), including the post’s:
<ul>
<li>date</li>
<li>title</li>
<li>content</li>
<li>excerpt</li>
<li>status and visibility settings (including the <a href="https://codex.wordpress.org/Using_Password_Protection" rel="nofollow ugc">post password</a> if set and whether or not the post is currently in the trash),</li>
<li>whether comments are on or off</li>
<li>whether <a href="https://codex.wordpress.org/Glossary#Pingback" rel="nofollow ugc">pingbacks</a> are on or off</li>
<li><a href="https://support.wordpress.com/geotagging/" rel="nofollow ugc">geolocation</a></li>
<li>featured images</li>
<li>media attachments, along with the actual media file itself</li>
</ul>
</li>
</ul>

WordPress Crosspost


I guess this plugin has been discontinued because it hasn't had an update in years. But it gives an error anytime the post contains an image, and it fails to post even if you save the post as a draft first. This causes the post to publish to the source Wordpress site with no image and nothing gets posted to the target Wordpress site. i had to disable the addon so I could post again since all my posts contain an image. The error does not happen if it's just a text-only post. 


Breaks when post contains images

WordPress Crosspost cross-posts content from your self-hosted WordPress blogs to your WordPress.com sites. Updates are crossposted, too.

Automatically share WordPress posts on <a href="https://pixelfed.org/" rel="nofollow ugc">Pixelfed</a>.
You choose which Post Types are shared—though sharing can still be disabled on a per-post basis. Posts without a Featured Image will not be shared. (The plugin currently doesn’t look for other images inside the post, that is.)
Supports a number of filter hooks for developers, and is fully compatible with WordPress’s new block editor.
More details can be found on <a href="https://jan.boddez.net/wordpress/share-on-pixelfed" rel="nofollow ugc">this plugin’s web page</a>.
