Types of files allowed to upload in WordPress

WordPress allows you to upload the most common image, audio/video, PDF, Microsoft Office and OpenOffice files. The WordPress codex has a full list of allowed file types and extensions.

Adding exceptions for additional file types

Security is the main reason behind limiting the types of files that users can upload. However, this does not mean that users cannot change this. Using a little bit of code, you can add a new file type and extension to WordPress.

For example, add this code to your theme's functions.php file or a site-specific plugin to allow the SVG file type to load:

 function my_myme_types ($ mime_types) $ mime_types ['svg'] = 'image / svg + xml'; // Añadiendo la extensión svg return $ mime_types; add_filter ('upload_mimes', 'my_myme_types', 1, 1); 

Notice that the file extension goes as the key in the associated $mime_types array and the mime type goes as its value.

In this example, the svg file extension represents files with the mime type image/svg + xml . You can find mime types of several common file extensions on this page.

You can also add multiple file types in one code snippet, like this:

 function my_myme_types ($ mime_types) $ mime_types ['svg'] = 'image / svg + xml'; // Agregar la extensión svg $ mime_types ['psd'] = 'image / vnd.adobe.photoshop'; // La adición de archivos de photoshop devuelve $ mime_types; add_filter ('upload_mimes', 'my_myme_types', 1, 1);
