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.
