Screen Reader Text Preview
Paste your HTML and see exactly what a screen reader would announce to users. Identifies missing alt text, empty links, unlabeled inputs, and missing landmarks so you can fix accessibility issues before they reach real users.
How Screen Readers Process HTML
Screen readers like NVDA, JAWS, and VoiceOver traverse the DOM (Document Object Model) of a web page sequentially. They announce each element based on its semantic role: headings are announced with their level, images are announced with their alt text, links and buttons are identified by their accessible name, and form inputs are read with their associated labels. ARIA landmarks like nav, main, and aside help screen reader users navigate quickly between major page sections. When these semantics are missing or incorrect, screen reader users encounter confusing, incomplete, or unusable content.
Common Accessibility Issues This Tool Detects
This tool scans your HTML for the most impactful screen reader accessibility issues. Missing alt text on images forces screen readers to announce the file name — or nothing at all — leaving blind users guessing at content. Empty links (with no text and no aria-label) are announced as just "link" with no indication of where they go. Form inputs without associated labels leave users unsure what information to enter. Missing landmark regions make it difficult for screen reader users to navigate efficiently. Each of these issues is flagged with specific guidance on how to fix it.
Improving Your HTML for Screen Readers
Start by ensuring every image has descriptive alt text (or alt="" for purely decorative images). Give every link and button meaningful text content or an aria-label. Associate form inputs with labels using the for attribute or by wrapping inputs inside label elements. Use semantic HTML elements like nav, main, header, footer, and aside instead of generic div elements. Structure your headings in a logical hierarchy (h1 through h6) without skipping levels. These changes dramatically improve the experience for the millions of people who rely on screen readers to access the web.
Web Speech API for Live Audio Preview
This tool includes a "Read Aloud" feature powered by the Web Speech API, which is built into modern browsers. It reads the screen reader output sequentially, giving you an approximate experience of what a screen reader user would hear. While it does not replicate the exact behavior of NVDA or VoiceOver (which have their own speech engines and navigation modes), it provides a useful audio preview of your content's accessibility. Use it alongside manual screen reader testing for the most thorough audit.
