Hotlink File Prevention (HFP) offers simple hotlink protection that can be turned on/off for individual files in the WordPress media library.
«Hotlinking» is when a file, such as an image or PDF, is linked to from another website or entered manually in a web browser’s location bar. HFP only allows your file to be viewed on your website.
Hotlink protection is provided via
.htaccess rules in the
Once the HFP plugin is activated, you will have two new features in the media library:
- Within the Screen Options tab (list view only), check box for the «Hotlink Prevention» column.
- To protect a file, edit the file and scroll down to the checkbox labelled «Hotlink Protection».
Any asset that is checked will have «Yes» displayed in the «Hotlink Prevention» column; otherwise, this column will be blank.
Note about «Open in new tab» option
When you use the «Open in new tab» option for links, WordPress adds
rel="noreferrer", which effectively makes the link act like direct access, and the link will be blocked for files protected using HFP.
- Go to «Plugins > Add New» in the WordPress admin area.
- Search for «Hotlink File Prevention».
- Install, then Activate the plugin.
For more installation options and instructions, see «Installing Plugins» on WordPress.org.
How does HFP work?
HFP creates an Apache
.htaccessfile in the
wp-content/uploadsdirectory. It sets a HTTP_REFERER check and RewriteRule for each file that has hotlink protection applied. Toggling hotlink protection on/off dynamically adds/removes RewriteRule statements.
Can it be used with any type of media file?
Yes, it works with any file that you upload to the media library.
Are my files absolutely safe using this plugin?
Here’s the deal: This plugin makes it harder for people to hotlink to your files, but if they are highly technical, they will be able to do things like fake the HTTP referrer.
Does it with with web servers other than Apache?
The server must process rewrite rules in
.htaccess. So HFP will work on Apache and LightSpeed servers, but not NGINX.
