Frequently Asked Questions
Yes, you can optimize up to 5 images per day completely free of charge and without registration.
No. Your images are temporarily sent to our AI for analysis and deleted immediately afterwards. We do not store any user data in the free tool.
An alt text generator is a tool that looks at your image, understands what’s inside it (products, people, objects, background), and writes a short, descriptive alt attribute so search engines and assistive technologies (screen readers) can understand the image.
It analyzes the image with AI, optionally adds your SEO keywords, and then returns clean, human-style alt text. On supported platforms (WordPress, WooCommerce, Shopware, Joomla, Drupal) it can write it back to the media/image automatically.
No. You can define a default writing style or prompt once (for product images, blog images, banners, featured images), and the generator will reuse it.
Yes. We provide plugins/extensions for WordPress–WooCommerce, Shopware, and Joomla, so you don’t need custom code. Just connect your site with the API key and start generating.
Yes. There’s a bulk mode for large media libraries or e-commerce catalogs. You can scan the library, select missing/weak alt texts, and generate for all in one run. This is useful when you migrate a site or inherit a store with no alt text.
You can choose. There’s an option to:
generate only for missing alt text, or
overwrite weak/auto-generated alt text that doesn’t meet your standard.
This is helpful when you want to “refresh” low-quality alt text across the site.
Yes. You can set included keywords (to inject product name, brand, category, color, SKU) and excluded keywords (to prevent generic AI words). This makes the output more relevant to your pages and helps image SEO.
The generator is designed to create descriptive, purpose-driven alt text so pages can meet accessibility requirements like WCAG 2.x, ADA, EAA and national accessibility rules. You should still review critical images (hero, infographics, CTAs), but it covers the majority automatically.
Common web formats like JPG, JPEG, PNG, WebP, SVG and AVIF are supported.
Yes. You can generate alt text in the languages your site uses (for example: English, German, French, Spanish, Italian) so each sales channel or locale gets the right description. This is important for multilingual SEO.
No. Images are processed to generate the text and the result is sent back to your site. The goal is to keep your media private while still giving you AI-quality descriptions. (You can store the generated text in your own database/media library.)
Yes. There’s a processing history where you can review which images were processed, what alt text was created, and re-generate or edit if needed. This helps agencies and stores to audit work later.
You can manually edit the generated alt text inside your CMS (Media Library, Product image, Article image). On the next run, you can also improve it with a stronger prompt or with keyword rules.
Both. Good alt text improves image understanding for Google (image search, product search, topical relevance) and makes pages accessible for screen readers — so you get SEO + compliance in one step.
Yes. You can run a crawler to find missing or empty alt text across the whole website, then send those images to the generator to fix them in bulk — ideal for big sites and agencies.
Typically each processed image uses 1 credit. You can start with a free/trial quota, and then upgrade to monthly, yearly, or one-time packs depending on how many images you have. (Exact numbers depend on your plan.)
Yes — you can connect several domains to the same account, as long as you have credits. This is great for agencies managing multiple WordPress/Shopware/Joomla sites.
