What Is Media File Renamer?
Media File Renamer is a WordPress plugin that automatically renames your media files (images, PDFs, and other uploads) based on their titles or rules you choose. This improves your SEO and makes file organization consistent and meaningful.
Renaming media files with keywords that match page content or alt text helps search engines better understand image relevance — improving visibility in image search and page rankings.
Why Clean File Names Matter
Many default WordPress media file names look like this:
- IMG_1234.jpeg
- Search engines don’t know what that means. But with SEO-friendly names like:
- best-pittsburgh-roofing-services.jpeg
- …you improve relevance for crawlers and help your images rank in Google Images and web search.
