AltText.ai vs Media File Renamer (2026): which should you pick?

Pick AltText.ai if

• Fits if your store or blog has hundreds of images with no alt text
• Works for multilingual sites that need alt text in several languages

Look elsewhere if

• Tight if you're just looking, as the 25 free credits are one-off and packs cost $3 for 50
• Pricey if you have lots of images, as 2,000 a month is $59 and 10,000 is $229
• Watch out: AVIF, HEIC, SVG and TIFF cost 2 credits and need a paid plan, and each extra language is 1 more
• Watch out: changing plans forfeits that period's unused credits, and used credits are usually not refunded
• Too light for your whole SEO setup, as it only writes alt text

Pick Media File Renamer if

• Fits if your media library is full of camera or download filenames
• Works for stores that want product images named after their products, on Pro

Look elsewhere if

• Skip it if your site isn't on WordPress, as there's no standalone app
• Tight if you stay free, since Vision AI, post title and ACF renaming, numbered names and metadata sync need Pro
• Watch out: the AI features run through Meow Apps' separate AI Engine plugin, according to the changelog
• Watch out: yearly licenses renew automatically, lifetime ones include support for the first year only, and refunds stop at 14 days
• Watch out: the maker advises a backup before renaming, as some plugins can keep the old file references

• Vision AI, post title and ACF renaming, numbered names and metadata sync need Pro.

AltText.ai

AI alt text

Describes each image in 130+ languages, with a choice of writing styles and character limits, for screen readers and search engines.

SEO keywords

Give it a page's target keywords and it works the relevant ones into the alt text, leaving out those that do not fit the image.

Final Pass prompt

A prompt of your own runs on every alt text after it is written, set for the whole account or per image, at no extra cost.

WordPress and Shopify

The WordPress plugin writes alt text for new uploads and has a bulk updater for old ones; the Shopify app and WooCommerce and Magento add product data.

Bulk tools

A web interface with a page scraper, CSV import and export, and imports from Dropbox and Pinterest for large image libraries.

API, MCP and connectors

A developer API, an MCP server, Zapier, Pabbly, Albato and SureTriggers connectors, and browser extensions for sites such as Squarespace.

Media File Renamer

Automatic renaming

Renames files on upload or later from their title or ALT text, and updates the references to them in posts and pages.

Manual and bulk renaming

Edit a filename from the Media Library, the edit screen or the Renamer dashboard, or rename the whole library at once, filtered by status.

Lock and undo

Lock files so they are never renamed again, lock them automatically after a rename, and revert to an earlier filename.

Vision AI

Pro looks at the image content to suggest a filename. The free version suggests names from existing metadata only.

More auto methods

Pro renames from the attached post title, an ACF field or an anonymized name, numbers files to avoid duplicates and handles transliteration.

Metadata sync and logs

Pro keeps titles, ALT text, captions and descriptions in line with the filename, and logs each rename in SQL for review or rollback.
