A SHORTER PATH FROM CHECK TO FIX

Check, decide, update

1. Scan a page

Paste a product page, article or landing page URL. See each image occurrence in source order.

2. Review its purpose

Separate missing descriptions from intentionally empty alt. The same image may have different jobs on different parts of a page.

3. Take the final text

Generate only where useful, edit the suggestion and copy the alt attribute or export your report. Apply it in your CMS.

READ THE RESULT CORRECTLY

Three results. Three different decisions.

An alt tag checker can find markup problems. You decide what each image contributes to the page.

01

Missing is not the same as empty

An informative product image needs an alt attribute. Describe visible features that help someone understand the item.

In the page

<img src="tote.jpg">

After review

<img src="tote.jpg" alt="Canvas tote with two handles">
02

Keep decorative images quiet

A background flourish beside an already clear heading may correctly use empty alt. Adding filler text would create noise for a screen reader.

In the page

<img src="flourish.png" alt="">

After review

Keep alt="" when purely decorative
03

Existing text still needs judgment

A filename is not a useful description. For a linked image, describe the destination or function when that is the image’s purpose.

In the page

<img src="bag.jpg" alt="IMG_2048.jpg">

After review

alt="Canvas tote with two handles"

QUESTIONS

About the image alt text checker

How do I check if an image has alt text?

Enter the webpage URL above. The report lists alt attributes from the initial HTML. You can also inspect an image’s HTML in your browser and look for alt. Use browser accessibility tools to review the rendered page and its accessible names.

Is an empty alt attribute an error?

Not necessarily. Decorative or redundant images may correctly use alt="". A meaningful image usually needs a description, and an image acting as a control needs an accessible name. Review the purpose before changing it.

Does this check every image on my website?

No. Each scan covers up to 100 image occurrences in one webpage’s initial HTML, with a 2 MB page limit. Images added by JavaScript, CSS backgrounds and inline SVG are outside this check.

Is checking free? What about AI suggestions?

Scanning, editing, copying and CSV export are free, with scan limits to prevent abuse. AI suggestions use the existing Alt Text Generator allowance: two shared daily trials for guests, or two credits per Model 1.0 suggestion when signed in.

Will better alt text improve my Google ranking?

Useful alt text helps people and gives search engines image context. It does not guarantee rankings. Describe the image’s purpose naturally and avoid repeated keywords or invented product details.

Does the checker update my site or certify accessibility?

No. Review and apply the final text in your CMS. Edits remain in this browser tab. Automated checks and AI suggestions cannot certify WCAG compliance or replace a full accessibility review.
