Overview of miChecker

miChecker is a tool designed to check website accessibility based on the international standard “Web Content Accessibility Guidelines (WCAG).” Specifically, it evaluates websites for compliance with WCAG 2.0 and WCAG 2.1 standards, automatically detecting accessibility issues on a page. By using miChecker, you can easily understand how accessible your website is and where improvements are needed.

miChecker allows you to input a webpage’s URL and automatically diagnoses accessibility issues. The results are visually presented, with problematic areas highlighted, so you can quickly see where improvements are needed.

2. WCAG Compliance Evaluation

The tool evaluates the site’s compliance based on WCAG standards (Levels A, AA, AAA). This helps you understand which level of accessibility your site meets and pinpoints areas that require improvement.

3. Detailed Reports

The diagnosis results are provided in a detailed report, including explanations of each issue and specific advice on how to fix them. The reports can be downloaded in PDF format, making it easy to share the findings with team members or stakeholders.

Enter the URL of the webpage you want to diagnose. You can also input multiple URLs for bulk diagnosis.

Click the “Start Diagnosis” button, and miChecker will automatically scan the page for accessibility issues. The scan can take a few minutes, depending on the size of the website.

4. Review and Improve

Once the diagnosis is complete, the results will be displayed, showing problem areas and details for each issue. Each problem is accompanied by a WCAG-based evaluation and advice on how to resolve it. Use this feedback to make necessary improvements to the website.

Important Points When Using miChecker
