WCAG Checker
Map common HTML issues to WCAG-style A/AA findings.
The WCAG Checker is an essential online utility for web developers, designers, and content creators committed to building an inclusive web. This specialized tool helps you proactively identify potential accessibility barriers within your HTML code. Need to check a new product page or a critical component? Instead of manually sifting through code, simply paste your raw HTML into the WCAG Checker. It meticulously scans for common issues like missing alt attributes on images, insufficient color contrast (when specified inline), improper heading structure, or unclear link texts.
Typical input is a segment or complete HTML document. The output delivers a clear, categorized list of findings, often pointing to specific lines of code and linking them directly to relevant WCAG 2.x A or AA success criteria. For example, it might flag <img src="logo.png"> as missing an alt attribute, referencing WCAG 1.1.1 (Non-text Content). While powerful for static HTML, remember it primarily assesses structural and semantic markup. It cannot fully evaluate dynamic JavaScript content, complex user interactions, or issues requiring human judgment, such as the appropriateness of alt text or custom component usability. Always complement automated checks with manual testing and real user feedback for comprehensive accessibility. Use this tool as a powerful first line of defense in your auditing workflow.
How to use WCAG Checker
Prepare Your HTML
Copy the HTML code you wish to analyze from your website, local file, or editor. Ensure it's the raw markup you want to assess for accessibility.
Paste into Checker
Navigate to the WCAG Checker tool page and locate the designated input area. Paste your copied HTML code into this text field.
Initiate Scan
Click the "Check WCAG" or "Analyze HTML" button to prompt the tool to begin scanning your provided code for common accessibility issues.
Review Findings
Examine the generated report, which will highlight identified accessibility problems, their locations in your code, and the corresponding WCAG success criteria.
Refine & Re-check
Make necessary corrections to your HTML based on the report's feedback. You can then paste the updated code back into the tool for a quick re-evaluation.
Frequently Asked Questions
What specific WCAG versions and conformance levels does the WCAG Checker support?
The WCAG Checker primarily focuses on identifying issues relevant to WCAG 2.x guidelines, including 2.0, 2.1, and 2.2, with a particular emphasis on A and AA conformance levels for most findings.
Can this tool check CSS styles or JavaScript interactions for accessibility?
No, the WCAG Checker specifically analyzes raw HTML structure and attributes. It does not directly interpret CSS for rendering issues or execute JavaScript to assess dynamic content accessibility.
How does the WCAG Checker handle embedded content like iframes or SVGs?
It will check the iframe tag itself for accessibility attributes like title but will not scan the content loaded within the iframe. Similarly, it assesses SVG tags for attributes but not their internal graphical structure for accessibility.
Is the WCAG Checker suitable for comprehensive accessibility audits?
While a powerful first step for identifying common HTML issues, it's not a standalone solution for comprehensive audits. A complete audit requires combining automated tools, manual testing, and feedback from real users with disabilities.
What kind of output can I expect from the WCAG Checker?
The output typically provides a clear list of detected issues, their severity, the specific line numbers or HTML elements where they occur, and a direct reference to the relevant WCAG success criterion they violate.
Does the WCAG Checker store any of my submitted HTML code?
No, the WCAG Checker processes your HTML entirely client-side within your web browser. Your code is not transmitted to our servers, ensuring complete privacy and data security.
