15 Best Accessibility Tools for 2025

As more countries establish policies to ensure the web is accessible to everyone, website owners need to know about the tools available to help make their sites compliant and inclusive.

What Is Web Accessibility?

Web accessibility is the practice of making digital content accessible to people with disabilities. According to the UN World Report on Disability (2011), about 15% of the world’s population—approximately 1.3 billion people—live with some form of disability. These numbers show that it’s not only a moral responsibility but also a practical choice to make websites accessible to all users.

Additionally, accessible websites often rank better in search engines because accessibility best practices overlap with SEO principles.

What Is WCAG?

WCAG is a set of guidelines that outline how to make digital content accessible. The current standard, WCAG 2.1, includes three levels of conformance—A, AA, and AAA—each with success criteria that guide developers in making websites accessible.

Several countries have adopted WCAG in their accessibility regulations, including the Americans with Disabilities Act (ADA), Section 508, EN 301 549, and AODA. Compliance with these standards is legally required in many cases and enhances the usability of websites for all users.

Why Web Accessibility Tools Are Essential for Compliance and Inclusion

As digital accessibility standards continue to evolve, web accessibility tools have become indispensable for ensuring that websites meet compliance requirements. These tools help identify, monitor, and address accessibility issues, making it easier for website owners to provide an inclusive experience for all users, including those with disabilities. By using these tools, developers can automatically detect errors, implement best practices, and optimize site elements like images, color contrast, and navigation. With both automated and manual solutions, web accessibility tools are now essential in maintaining WCAG and ADA compliance while enhancing the user experience.
