The File Upload Types by WPForms is a WordPress plugin designed to enhance file upload functionality on websites. By default, WordPress limits the types of files that users can upload to the media library, often resulting in errors when users attempt to upload unsupported file types. This plugin enables website owners to easily add support for a wide variety of file extensions and MIME types, allowing for a more flexible user experience.

With the File Upload Types plugin, users can manually adjust the internal file whitelist, granting permission for uploads of virtually any file type, including popular extensions such as .ai, .zip, .xml, .svg, .csv, .mobi, and more. This feature is particularly beneficial for websites that require specific file uploads for forms or submissions, providing a seamless solution to the common restrictions imposed by WordPress.
