Everything You Need to Organize Your WordPress Media Library
Sigma Media Manager combines media organization, automation and optimization tools into one powerful plugin.
Key features

Instead of installing multiple plugins, Sigma Media Manager provides a complete media management system built into WordPress.
The Problem With the Default WP Media Library
The default WP media library works for small websites, but becomes difficult to manage as your site grows.
Common problems include:
- No folders for organizing files
- Thousands of media files in a single list
- Difficult file discovery for teams
- Unused files consuming server storage
- Missing image metadata affecting SEO
Sigma Media Manager solves these issues by transforming the default media library into a fully organized file management system.
Organize Your WP Media Library with Folders
Sigma Media Manager adds a complete folder system to the WordPress media library, so you can organize files however you want. Create unlimited folders and nested subfolders for images, videos, documents, and other assets.
