Media File Renamer is a WordPress plugin that renames your media filenames. It can be automatic (depending on certain conditions) or manual. It is excellent for SEO and to keep WordPress tidy. The references to those filenames on your website will be also updated.
A new column in the Media Library will be displayed. By default, Media File Renamer recommends you an ideal filename based on the title of this media.
By clicking on the button, the files will be renamed directly. You can lock or unlock this automatic process by using those little icons.
This allows you to organize your renaming tasks efficiently.
The Pro version was created almost two years after the first release of the Free version. It adds requested features, such as the Manual Rename. You can edit the filenames of your Media directly, through the Media Edit screen or through the Media Library.
The Free version only allows you to rename your files based on the title of this media. With the Pro, you can also do it based on the title of the post this media is attached to (or any other post types, such as pages, products, etc) or based on the ALT text.
If you are interested all the files at once, you can do it through the dashboard of Media File Renamer.
I recommend you to use the default options. Then to use manual renaming for special cases or when titles are too similar.
If you need to customize your renaming, you can 🙂 There are many filers and actions you can use. Have a look at FAQ & Issues.
