FAQ
-
How does the AI alt text generator work?
-
Altomatic uses advanced AI to analyze each image and generate descriptive, SEO-friendly alt text automatically. The AI understands image content, objects, people, and context to write accurate descriptions. This saves you hours of manual work and ensures accessibility compliance.
-
Will image compression overwrite my originals?
-
No. Altomatic preserves your original images and creates optimized WebP/AVIF versions alongside them. You can always restore or re-optimize.
-
What image formats does Altomatic support?
-
Altomatic accepts JPEG, PNG, and GIF uploads and can convert them to:
– WebP – 25-35% smaller than JPEG with same quality
– AVIF – Up to 50% smaller than JPEG (newest format)
– Optimized JPEG – For browsers that don’t support WebP/AVIF -
Why use Altomatic instead of separate compression and alt text plugins?
-
Most WordPress users need two plugins: one for image compression and one for alt text. Altomatic combines both features, saving you money and reducing plugin bloat. One dashboard, one subscription, complete image optimization.
-
Will this help my Core Web Vitals score?
-
Yes! Image optimization directly improves Largest Contentful Paint (LCP), one of the three Core Web Vitals. Smaller images = faster page loads = better scores. Images cause 80% of LCP issues on most sites.
-
Does it work with WooCommerce?
-
Yes. Altomatic automatically optimizes WooCommerce product images, thumbnails, and gallery images. AI-generated alt text also helps your products appear in Google Image search and improves product page SEO.
-
Does Altomatic help with accessibility compliance (EAA, ADA, WCAG)?
-
Yes. The European Accessibility Act (EAA) and ADA require alt text on informational images. Altomatic automatically generates accurate alt text for every image, helping you meet WCAG 2.1 requirements without manual work.
-
Can I bulk optimize existing images?
-
Yes. Altomatic includes a bulk optimization tool that processes your entire media library. Optimize hundreds of images with one click.
-
How are credits used?
-
Credits are used per operation (1 credit per image size/format, 3 credits for alt text generation). Free tier includes 50 credits/month. Monitor usage at altomatic.ai/profile.
-
Is my data secure?
-
Yes. Images are transferred via HTTPS and temporarily processed on our servers. We don’t store or share your images beyond what’s needed for optimization.
