<p>Pro Mime Types adds a nifty (network) admin interface for allowing or blocking many file extensions for uploading media, documents, and other attachments.</p>
<p>It also shows you a list of all allowed MIME types on the site or network.</p>
<ul>
<li>When a MIME type is allowed, users who can upload files can now do so for that MIME type.</li>
<li>When a MIME type is blocked, users see an error that the file isn’t allowed for security reasons.</li>
</ul>
<p>For WordPress Multisite networks, you can enable this plugin in network mode to control MIME types for the entire network.</p>
<h3>Features</h3>
<ul>
<li>You can control many MIME types and extensions for upload via a modern interface.</li>
<li>Pro Mime Types comes preconfigured by enabling many safe MIME types.</li>
<li>View all allowed MIME types for the site (also those enabled by other plugins).</li>
<li>Every MIME type comes with a security summary explaining why you should or shouldn’t allow it. To view the summary, hover the mouse cursor over the big colored icon.</li>
<li>Accessibility is at the forefront. For example, you can use full keyboard navigation, even for tooltips.</li>
<li>Adds text, code, and miscellaneous file types to the Media Library for sorting.</li>
<li>The Media Library gains support for more file types for sorting images, audio, video, documents, spreadsheets, and archives.</li>
</ul>
<h3>Multisite support</h3>
<p>This plugin can run in network mode, where all sites are allowed one set of MIME types. You can configure the allowed MIME types via the network administration UI.</p>
<p>Alternatively, Pro Mime Types can run in single-site mode, where every subsite has custom-allowed MIME types. Only the network administrator can assign these on a per-site basis.</p>
