Pathologic

Pathologic is an input filter which can correct paths in links and images in your Drupal content in situations which would otherwise cause them to “break;” for example, if the URL of the site changes, or the content was moved to a different server. Pathologic can also solve the problem of missing images and broken links in your site’s RSS feeds. See more example use cases on the documentation page.

Note: Pathologic’s activity queue has seen a relative burst of activity recently. While I appreciate the contributions, I’m not currently in a position in life where dedicating unpaid time to maintaining a project I myself no longer use would be prudent. If you would like to see further development on Pathologic, including a proper late-D8/D9 port, please consider sponsoring me to develop this module. I apologize for the inconvenience.

Pathologic is designed to be a simple, set-it-and-forget-it utility. You don't need to enter any special “tags,” path prefixes, or other non-content noise into your content to trigger Pathologic to work; it finds paths it can manage in your content automatically.

As Pathologic is an input filter, installation and configuration is a little more difficult than it is for a standard module — but it's still not that tough, if you follow the full installation and configuration guide here.
