Media File Renamer Review 2026: AI Vision Renaming for a Tidy, SEO-Friendly Media Library

Media File Renamer is a WordPress plugin by Meow Apps that replaces camera-default filenames like IMG_4471.jpg with clean, descriptive, SEO-friendly names — automatically or manually — and rewrites every reference to the file across your site so nothing breaks. The free version renames from titles and metadata; Pro, from $39 a year on the vendor’s own site, adds AI Vision, which looks at the image itself and proposes a filename based on what is actually in the picture.

What it is

Media File Renamer is listed on WordPress.org as “Media File Renamer: Rename Images & Files for SEO (AI-Powered)” (version 6.3.3, updated October 2026, 40,000+ active installs, rated 4.6 out of 5 from 447 ratings), from Jordy Meow, the developer behind AI Engine. WordPress keeps whatever filename a camera, phone or stock download arrived with, and those names tell search engines, screen readers and you nothing. This plugin fixes the name and everything attached to it: rename a file and it updates the references in your posts, pages and metadata, and can sync the Title, ALT text, caption and description to match.

The renaming methods cascade. You order your strategies — title, ALT text, attached post title, or AI — and the plugin falls back to the next one when the first produces nothing useful. Work happens one file at a time from the Media Library or Edit screen, or across the whole library from the Renamer Dashboard, filtered by Pending, Never Renamed or Locked status.

Key features

• AI Vision renaming (Pro). AI analyzes the image content itself and suggests a descriptive filename based on what is in the picture, then can fill in the Title, ALT text, caption and description to match — turning a renaming pass into an accessibility and SEO pass. The vendor also notes that, through AI Engine and MCP, an AI assistant can do this renaming work for you.
• Full reference updates. Every rename rewrites references across posts, pages, metadata and page builders automatically. It handles retina and WebP variants, the re-scaled images WordPress has generated since 5.3, PDF thumbnails and UTF-8 filenames.
• Cascading auto methods. Chain renaming strategies with automatic fallback, and auto-rename new uploads on arrival based on title, ALT text, post title or AI vision, so the library stays tidy without a recurring chore.
• Lock, preview and Undo. Lock files you have named deliberately so they are never touched again — with an option to auto-lock after any rename — preview every change before applying it, and use Undo to revert filenames if a rename goes wrong.
• Bulk operations and file moves (Pro). Rename the entire library at once, move files into better folders in bulk with references updated, anonymize filenames for privacy, and append incrementing numbers to avoid duplicate names.
• Metadata sync and SQL logging (Pro). Keep filenames, ALT texts and titles aligned automatically after renaming, and log every rename operation for transparency and rollback.

Pricing

The plugin on WordPress.org is free, covering auto-renaming when a media title is updated, manual renaming from the Media Library, Edit screen or Renamer Dashboard, AI suggestions based on metadata, lock and unlock, and the Undo button. Pro is from $39 a year on the Meow Apps site, and adds Vision AI, advanced transliteration for complex language and encoding cases, the enhanced auto methods (ALT text, anonymization, attached post titles), numbered filenames, metadata sync and SQL logging. One honest cost note: AI Vision works through AI services, so heavy AI renaming runs on the AI setup you connect rather than being an unlimited free extra inside the licence.

Who it’s for

• Sites with years of camera-named uploads — photographers, publishers and stores whose libraries are full of IMG_ and DSC_ files that say nothing to Google or to a human searching the library later.
• SEO and accessibility cleanups — a bulk AI Vision pass that renames the file and fills in its Title and ALT text together is far faster than editing attachments one by one.
• Anyone burned by manual renaming before — the lock, preview and Undo system, plus automatic reference rewriting, is the difference between tidying and breaking a site.

What to watch out for

• Renaming is inherently risky — the vendor says so first. Its own listing warns you to back up before using it, start by renaming files individually, and clear your cache if references look stale afterwards. Take that seriously on a large library.
• Some page builders can block clean renames. Builders that store image references in encrypted or encoded form — the listing names the Avia Layout Builder as an example — may limit what any renamer can rewrite.
• The best AI is Pro. The free version’s AI suggestions work from metadata; the AI Vision that actually looks at the image, along with metadata sync and bulk folder moves, requires Pro from $39 a year.
• A strong but not perfect record. A 4.6-star average across 447 ratings is genuinely good for a utility that touches every file on a site, but the minority of unhappy reviews are exactly the broken-reference stories the backup warning is about.
• Research-based review. This review is based on the plugin’s WordPress.org listing and the vendor’s own site; we have not run Media File Renamer across a production media library ourselves.

Pros

• Established and widely used: 40,000+ active installs and 447 WordPress.org ratings.
• Renames the file and rewrites every reference, including retina, WebP and re-scaled variants.
• AI Vision (Pro) names files from the image itself and syncs Title, ALT text, caption and description.
• Safety tooling done right: locking, preview before applying, Undo, and SQL logging on Pro.
• Free version is genuinely useful — auto-rename, manual rename, metadata-based AI suggestions and Undo.

Cons

• AI Vision, metadata sync, numbered filenames and bulk moves are Pro-only, from $39/year.
• Bulk renaming without a backup can break references, especially with some page builders.
• AI renaming depends on an AI connection you set up; it is not a bundled, unlimited service.
• Pro transliteration and anonymization are niche — many small sites will never use half the Pro list.

Frequently asked questions

Is Media File Renamer free?

The core plugin is free on WordPress.org, including auto-renaming when titles change, manual renaming, AI suggestions from metadata, locking and Undo. Pro, from $39 a year on the vendor’s site, adds AI Vision renaming, metadata sync, numbered filenames, SQL logging, advanced transliteration and bulk folder moves.

Will renaming files break images on my site?

The plugin rewrites references across posts, pages and metadata automatically, and handles retina, WebP and re-scaled variants. The risk is not zero: some page builders store references in encoded form that cannot be rewritten, which is why the vendor tells you to back up first, rename a few files individually to test, clear your cache if anything looks stale, and use Undo to revert if needed.

How does the AI Vision renaming work?

On Pro, the AI looks at the image itself — not just its title or metadata — and proposes a descriptive filename based on the picture’s content, with the option to sync the Title, ALT text, caption and description to match. You can preview and edit suggestions before applying them, and lock any file so automation never renames it again.
