Media File Renamer is a WordPress plugin that renames your media files. It can be automatic (depending on certain conditions) or manual. It is excellent for SEO, to keep your WordPress tidy and to avoid issues related to files. The references to those filenames on your website will also be updated. It has many features, and if you are a developer you can automate the whole process and how the renaming is performed.
Media File Renamer, by default, automatically renames the filenames of your Media entries based on their titles. You can trigger this, or you can let it happen every time you modify titles. You can also rename the files manually. The references to those files will be also updated (posts, pages, custom types, metadata, etc…). You can use the Media Library, or the Media Edit screen.
However, it is highly recommended to use the pretty and very dynamic Renamer Dashboard. If you like to work fast and well, you will really love working with this modern dashboard
