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.
In the Media Library (or in the Edit Media) screen, you will be able to rename the file exactly the way you like.
Additional Auto Methods
There are additional methods for auto-renaming your files: depending on the post/page the media entry is attached too, for example, or depending on the ALT text.
If the ideal filename already exists, a number will be appended, and increased if needs to be.
Every SQL requests performed by the Renamer will be logged, as well as the anti-requests (for rollback purposes).
The ALT text will be synchronized via the renaming, depending on the method you chose.
If you like your filenames to be very pure, that feature will help you to achieve that.
