Turn images into publish-ready alt text

Get a practical first draft that avoids vague captions, keyword stuffing, and unsupported guesses.

Avoid vague captions

Instead of returning "image of a product," the draft names the visible subject and the detail that matters.

Stay with what is visible

The output avoids inventing brand names, claims, identities, or hidden product details that are not shown.

Keep SEO readable

SEO-friendly mode adds useful subject context without turning the alt attribute into a keyword list.

Match the page context

Accessibility mode focuses on what a reader would miss in this page if the image was not available.

Flag decorative images

Decorative check mode helps spot images that should use an empty alt attribute instead of extra noise.

Fit product pages

Product mode prioritizes visible type, color, shape, material, and presentation details shoppers can use.

Decide what the image is doing on the page

The same image can need different alt text depending on where it appears. A product photo, a chart, a decorative banner, and a blog thumbnail should not be described the same way.

When it adds meaning

Write the information a reader would miss if the image did not load or was read aloud.

When it is decorative

Use an empty alt attribute so screen readers can skip visuals that do not add content.

When it contains text or data

Include the meaningful text, trend, or takeaway instead of listing every visual detail.

AI Alt Text Generator FAQ

Friendly answers for the moments when alt text feels unclear: what to write, what to skip, how much detail to include, and when to review an AI draft before publishing.

1

What does this AI alt text generator create?

It gives you a clear first draft instead of making you stare at an image and wonder what counts as useful. Upload an image or paste an image URL, and the tool can return a recommended alt text, a shorter version, a more detailed version, an SEO-friendly option, an accessibility note, and an HTML example you can copy into your page.

2

How do I add the generated alt text to my website?

Copy the recommended text into the alt text field for that image. In WordPress, Shopify, Webflow, and most CMS tools, the field is usually called Alt Text, Alternative Text, or Image Alt. If you are editing HTML directly, place it in the alt attribute, such as <img src="image.jpg" alt="Concise description of the image.">.

3

How should I choose the right alt text mode?

Start with the page's job. Standard Alt Text works for most images. SEO Alt Text helps when search context matters, as long as the wording still sounds natural. Accessibility Alt Text is best when the image carries meaning a reader would miss. Short Alt Text fits thumbnails and compact layouts. Detailed Alt Text helps with richer visuals. Decorative Check is useful when you are unsure whether the image should be described at all. Product Image and Blog Image are tuned for ecommerce and editorial pages.

4

How long should alt text be?

It does not need to be perfect or overly polished. Aim for the shortest wording that still explains why the image matters on the page. A small icon or thumbnail may only need a few words. A product photo, screenshot, chart, or instructional image may need a full sentence. If the description starts feeling like a paragraph, it may belong in nearby body text instead.

5

Should every image have alt text?

Every meaningful image should be handled, but that does not always mean writing a description. If an image adds information, give it useful alt text. If it is decorative, repeats nearby text, or does not help someone understand the page, use an empty alt attribute: alt="". That choice is not neglect; it prevents screen reader users from hearing extra noise.

6

Is SEO alt text different from accessibility alt text?

They overlap more than people expect. Good SEO alt text is still good human-facing alt text: clear, specific, and honest about what is visible. Accessibility should come first. Add search context only when it genuinely helps describe the image. Skip keyword stuffing, repeated phrases, ranking promises, and details the image does not actually show.

7

What should I do with charts, screenshots, or images that contain text?

Try to describe what the reader needs to understand, not every visible pixel. For screenshots, mention the important interface, message, or state. For charts and diagrams, summarize the main takeaway in the alt text and put fuller details nearby if the data is complex. For images of text, include the meaningful text unless the same words already appear on the page.

8

Can I use this for product images?

Yes. Product Image mode focuses on details shoppers can actually use, such as item type, color, material, shape, packaging, style, and how the product is presented. Before publishing, check the draft against your listing. Add brand names, model numbers, benefits, or specifications only when you know they are correct.

9

How are my uploaded images and generated results handled?

Your image is used to display the preview and generate the result in real time. After processing is complete, the uploaded image is deleted immediately. We do not store uploaded images, keep image history, or save generated alt text results. If you want to keep the wording, copy it before leaving the page.

10

Can I publish AI-generated alt text without editing it?

Sometimes the draft will be ready to use, but it is still worth a quick review. Alt text depends on the page context, not just the pixels in the image. Check that the wording matches what the image is doing on your page, and watch for incorrect guesses, sensitive details, brand names, people, medical or legal content, or anything the image does not clearly show.
