Alt Text Generator

Generate Alt Text That Helps You Rank in AI & Image Search

Create SEO-optimized, accessibility-friendly alt text for every image on your page in minutes - so Google, AI overviews, and screen readers all understand your content.

Why Image Alt Text Matters for AI, SEO, and Accessibility

Image Alt text tells search engines, AI systems, and screen readers what your images are actually about.

Helps you rank in Google & Image search

Descriptive, keyword-aware alt text gives search engines more context, which can improve visibility in image results and organic search.

Helps AI understand your content

When AI tools like ChatGPT and Perplexity "read" your page, strong alt text makes it easier for them to interpret visuals and include that context in answers.

Makes your site accessible to everyone

Screen readers rely on alt text to describe images for visually impaired users, which is essential for good UX and often required for compliance.

If your images don't have strong alt text, you're leaving search, AI visibility, and accessibility on the table.

Signs Your Image Alt Text Is Holding You Back

If any of these sound familiar, your images probably aren't doing as much for SEO, AI visibility, or accessibility as they could.

You're manually writing alt text and it's taking way too long.

Half your images have no alt text, and SEO audits keep flagging it.

You're pasting generic descriptions that don't help you rank or support accessibility.

You're losing image and AI search visibility to competitors with better-optimized visuals.

How the Alt Text Generator Helps

Turn every image on your page into something search engines, AI tools, and screen readers can actually understand - without writing a single line of alt text yourself.

Lightning fast alt text at scale

Enter a web page URL and get professional alt text for every image in minutes, instead of spending hours writing them one by one.

SEO- and AI-aware descriptions

Each alt text is descriptive and keyword-aware, helping your images contribute to Google rankings, image search, and AI overviews - without sounding spammy.

Context-aware, not generic

The AI looks at the full image and surrounding content, so you get specific descriptions (products, people, scenes) instead of vague "image of…" text.

Frequently Asked Questions

How accurate is the generated alt text?

The tool analyzes both the image and the surrounding page context to generate specific, human-readable descriptions—not just "image of…" placeholders. You can always review and tweak any alt text before publishing.

What types of images does this work best for?

It works well for product photos, lifestyle shots, blog images, screenshots, and most marketing visuals. The more context your page provides, the better the descriptions.

Can I edit the generated alt text?

Yes. You stay in full control. Use the generated alt text as-is or adjust wording and keywords to match your brand voice or SEO strategy.

How does this help my SEO and AI visibility?

Good alt text gives search engines and AI systems more context about your images. That can improve visibility in Google Images and organic search, and helps AI tools better understand your content when generating answers.

Can I bulk-process pages or large sites?

You can generate alt text for every image on any page you run through the tool. For larger sites, start with your highest-value pages—like product/category pages and top blog posts—and work through them in batches.

How long does processing take?

Most pages are analyzed and processed in a few minutes, depending on how many images they contain. You'll see alt text for each image in a single, consolidated view.

Is my data secure?

We only analyze publicly accessible pages and images. We don't use your images for any other purpose, and you're always in control of where and how the generated alt text is applied.
