This is the one I would point at first if somebody asked what the plugin actually changes about running a WordPress site, and it is the one people are most surprised to find in the free version.
Every WordPress media library over about two years old is the same room: a few thousand files, a third of them unused, most of them larger than they need to be, all named IMG_4471 and screenshot-2. The library is technically searchable and practically not, because filenames carry no meaning and there are no folders.
The Media Library Manager is a full manager for that library, and it is worth going through what it actually does, because there is a lot in there.
Folders and tags, which are not the same thing
Folders answer where does this belong, and a file lives in exactly one of them. Tags answer what is this about, and a picture can carry as many as you like. Most libraries want both: a small number of folders reflecting how work arrives, and generous tags reflecting how work is looked for.
Both are stored as ordinary WordPress taxonomies. That detail matters more than it sounds: your organization is not locked inside a plugin’s own tables. It exists in WordPress, it survives, and other things can see it.
Drag images between folders, multi-select with Shift and Ctrl the way you would expect, and then move, tag, set as featured image or delete in bulk.
Search that actually finds things
Here is the part people refuse to believe, and it is really a small neural model running in your browser. Type a phrase describing what you are looking for, and it finds images by what they show rather than by what they are called.
Search for people smiling outdoors and you get people smiling outdoors, including the file called DSC_0442.jpg that nobody has ever been able to find again. No filename, no alt text, no manual tagging required.
It runs locally, which is the part I care about. There is no API key, no per-image cost, and no upload of your customers’ photographs to somebody else’s server. On a big library the first pass takes a moment while it reads everything, and after that it is instant.
And the search combines with the filters rather than replacing them, so you can narrow a semantic result by color, file type, orientation, size, author and date, then sort what remains.
Filtering by color
The row of color dots above the grid is the filter I did not expect to use and now use constantly. Click one and you get every image whose dominant color sits in that range.
It sounds like a novelty until you are building a page and need a photograph that will not fight the blue in your design. Then it is the fastest route to a shortlist there is.
Smart folders
Three of them fill themselves. Missing alt text collects everything with an empty alt attribute, which turns a vague accessibility worry into a finite list you can work down. Unused collects files nothing links to. Reclaim space collects the oversized originals that are inflating your backups.
And any search you build can be saved as your own smart folder, so a filter you keep rebuilding becomes a permanent entry in the sidebar.
The housekeeping tools
At the bottom of the sidebar sits a set of operations that would otherwise be four separate plugins.
Suggest folders clusters similar images so a flat library can be organized in one pass rather than one file at a time. Find duplicates groups near-identical images for review with a keep-or-trash choice per image, which is the safe way to do it, because automatic duplicate deletion is how people lose the wrong copy. Rename by pattern fixes the IMG_4471 problem across the whole library. Regenerate thumbnails, Find broken files and Add Watermark round it out, Optimize images opens the Image Processor from WunderPaint Pro, and Generate Metadata fills in titles, alt text and descriptions in bulk.
Uploading is smarter here too
Files dropped into the manager are checked against your library for near-duplicates before they are imported, which stops the same photograph arriving for the fourth time. They land straight in the folder you are looking at. And on the way in they can be optimized, converted to WebP, downscaled and described.
That last part is the habit that keeps a library clean rather than cleaning it up later: name it, describe it and size it at the moment it arrives, while you still remember what it is.
PDFs upload too and appear under the Documents type, which is useful more often than it sounds.
The list view
The grid is right for finding pictures. The list view is right for auditing them, because it shows the metadata columns: dimensions, file size, type, date. When you are hunting for the reason your uploads folder is eight gigabytes, this is the view you want.
