About This Tool
Review common accessibility signals for images, alternative text and ARIA usage on a web page. The tool helps developers identify markup that may create barriers for screen-reader and assistive-technology users.
How to Use It
Enter the page URL supported by the tool and run the audit. Review the reported elements, identify missing or questionable accessibility attributes, then verify the final implementation with a broader accessibility test.
How the Calculation or Check Works
The audit checks detectable HTML attributes and patterns rather than declaring a site fully WCAG compliant. Automated checks can identify common issues, but human review is still required for context, meaningful alt text and interaction behavior.
Practical Example
An informative product image should normally have meaningful alternative text, while a purely decorative image may use an empty alt attribute. An ARIA label should describe an interactive control when its accessible name is otherwise unclear.
Frequently Asked Questions
Does this certify WCAG compliance? No. It is an automated diagnostic and should be combined with manual accessibility testing.
Why does alt text matter? It provides a text alternative when an image cannot be perceived visually.
Can automated accessibility checks replace manual testing? No. Context, keyboard behavior and actual assistive-technology output require human verification.
