Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site.

Overview

About this plugin

Two jobs your media library needs doing, and nobody has time to do by hand.

Compression to WebP. Every image you upload becomes WebP at a size you choose, keeping every thumbnail WordPress made. Your existing library can be converted in place.

This runs on your own server, costs nothing, and has no limit — with or without an account.

A library audit. jpg, and everything still sitting in JPEG or PNG. It is usually more than people expect.

Titles, alt text and descriptions written by AI. Not generic captions — written from keywords you set once, for the products you actually sell. Filenames can be renamed to match, which is what decides whether an image is found in Google Images at all.

Every market you sell into. The same photo described in Polish for Poland and German for Germany, each with the words people search with in that country — not a word-for-word translation of the first one.

What it costs

Compression and the audit are free, on every plan, without limits. They run on your server and cost us nothing.

Twenty-one languages, not just English. The plugin’s own screens speak English, Polish, German, Spanish, French, Italian, Portuguese, Dutch, Czech, Slovak, Romanian, Hungarian, Turkish, Bulgarian, Croatian, Greek, Ukrainian, Finnish, Swedish, Danish and Norwegian — complete, not half-finished. It follows your WordPress language on its own, or you set it separately in the settings.

What you pay for is the writing: one description is one image in one language. A free account covers five, without a card, so you can see what it writes about your own products before deciding.

External services

This plugin relies on one external service.

The AI writing happens on our servers, not on yours, so some data leaves your site. In detail:

  • Service: ConverterSEO API, at https://api.converterseo.com, operated by DESEO DESIGN sp. z o.o. (Katowice, Poland).
  • When: when you press a button that writes something, and when one of the plugin’s own admin screens opens — that second call only asks which plan you are on and how much of your allowance is left, and the answer is cached for 15 minutes. Never on the front end, never for your visitors. With no licence key connected the plugin makes no outbound request at all.
  • What is sent with every request: your licence key, and your site address. The address is what lets us tell you which of your sites a licence is being used on, and refuse one more than your plan covers.
  • What is sent when writing: the image itself, its file type, the language you chose, and — when you ask for a rewrite — the title, alt text and description the image already has.
  • What is never sent: anything about your visitors, your posts, your users, or your database. There is no analytics and no tracking of any kind.
  • Onward processing: to write the description, our server sends the image to Anthropic PBC (USA). It is not used to train models.
