Alt-Text Optimizer Pro in the Shopware administration: list of images without an alt text, including status, related product and actions.

Right inside the Shopware administration – no extra tool, no developer needed.

Why alt texts drive revenue and reduce risk

Missing alt texts are not a cosmetic problem. They cost you visibility, hold back accessibility and tie up working hours you can’t spare.

  • Visibility on Google

    Search engines don’t “see” images – they read the alt text. Without it you give away rankings in Google Image Search and valuable signals for your shop’s overall ranking.

  • Accessibility & compliance

    Accessibility rules such as the European Accessibility Act require many online shops to make their content accessible. Meaningful alt texts are a mandatory building block – and they save you expensive rework later.

  • Impossible by hand

    A typical shop has hundreds or thousands of product images. Writing every alt text manually costs days of work – time your team doesn’t have.

What Alt-Text Optimizer Pro does

  • AI-powered image analysis

    Uses the OpenAI vision models (GPT-4o mini by default) to “understand” your images and write fitting, natural-sounding alt texts.

  • Multilingual

    Alt texts in German, English, French, Spanish, Italian or Dutch – the language is detected automatically from the shop context.

  • Product context

    If you want, the product name and description feed into the generation – for accurate descriptions instead of generic filler.

  • Full control over length

    Set a minimum and maximum length. Texts that come out too short are discarded, overly long ones are trimmed cleanly – ideal for SEO (recommended: 80–125 characters).

  • Control resolution & cost

    Choose between low (fast & cheap), high (more detail) or automatic image resolution, and cap the number of tokens per request.

  • Configurable per sales channel

    Every setting can be overridden per sales channel – for different languages, models or budgets in each shop.

What it costs – and what you save

Many alt text services bill per image and get more expensive with every upload. Here you pay your direct OpenAI cost – plus the one-off license.

Other alt text services

  • Priced per image – often several cents to euros
  • Recurring subscription that grows with every image
  • Doesn’t know your product – generic descriptions
  • Your data travels through someone else’s platform

Alt-Text Optimizer Pro

  • Only your OpenAI cost: fractions of a cent per image
  • A one-off plugin license instead of a per-image subscription
  • Uses product name & description as context
  • Your own OpenAI key – full cost and data control

For example: 1,000 product images typically cost just a few euros in OpenAI fees with GPT-4o mini and low resolution – once, not per month.

Frequently asked questions

Why bother with alt texts at all?
Alt texts are what Google “reads” about an image – without them you give away rankings in image search and in your overall ranking. They are also a core building block of accessibility, which is now legally required for many online shops in the EU. Doing hundreds or thousands of product images by hand is barely feasible – that is exactly what the plugin takes off your plate.
Does this pay off compared to other alt text services?
Usually yes. Many online services charge anywhere from a few cents to several euros per image and know nothing about your product. Here you pay the OpenAI cost directly – with GPT-4o mini and low resolution that is fractions of a cent per image – plus the one-off plugin license. Full cost transparency, no per-image subscription, and the texts can take your product context into account.
How quickly is it set up?
In a few minutes: install the plugin, add your OpenAI API key once, done. After that you generate alt texts straight from the administration – no code, no developer.
Do I need my own OpenAI account?
Yes. The plugin uses your own OpenAI API key, so the costs are billed transparently through your OpenAI account. You can create the key for free at platform.openai.com.
Which languages does the plugin work in?
Alt texts can be generated in German, English, French, Spanish, Italian and Dutch. The language is determined automatically from the shop context; you set a default language as a fallback.
Do I stay in control of the texts?
Always. Generated alt texts land in the normal alt text field of the media item and are flagged as “AI-generated” – you see them collected in a dedicated list and can regenerate, edit or remove them at any time.
Which Shopware version is the plugin built for?
Alt-Text Optimizer Pro is built for Shopware 6.7.
