EqualWeb – Media Alt & Transcript Checker

About

Detailed Description
EqualWeb Media Alt & Transcript Checker is a comprehensive accessibility tool that helps developers and content creators ensure all media elements on their web pages meet WCAG 2.2 accessibility requirements.

Why Media Accessibility Matters
Users who are blind or have low vision rely on alt text to understand images. Deaf and hard-of-hearing users need captions for videos and transcripts for audio content. Without these alternatives, significant portions of web content become inaccessible.
