ACF Uppy Field is a WordPress plugin that adds a new "Uppy" custom field to the list of fields of the Advanced Custom Fields plugin.
This "Uppy" custom field allows you to overcome the limits of the default "File" field present in ACF, and to upload files of all types and sizes via the TUS protocol and the Uppy JS uploader, regardless of the limits set on the server side (there is no need to increase INI parameters like upload_max_filesize, post_max_size, max_execution_time, memory_limit, etc.).
