Accessibility

We want every tool to be usable by everyone. Here's what we do and how to report an issue.

Our approach

Utilities Bunker is committed to making its tools and content accessible to as many people as possible. We aim to follow the Web Content Accessibility Guidelines (WCAG 2.1 AA) as a baseline and improve continuously.

Because the site is built around calculators, converters, and visual tools, we focus on clear structure, readable output, and keyboard-friendly interactions.

Accessibility features

  • Semantic HTML — landmarks, headings, and labels for assistive technologies
  • Keyboard navigation — all interactive controls are reachable and operable without a mouse
  • Focus indicators — visible focus rings on every interactive element
  • High-contrast theme — dark mode with AA-compliant contrast ratios
  • Responsive layout — mobile, tablet, desktop, zoom to 200% without loss of content
  • Reduced-motion support — honours prefers-reduced-motion for animations
  • Clear validation — tool outputs use plain language and structured markup
  • No forced autoplay — nothing plays sound or video without user action

Known limitations

Some tools present complex visual outputs — tables, charts, hex editors, binary visualisations — that may not be perfect for every assistive technology or browser combination. Image-conversion previews in particular can be hard to describe without a mouse.

If you find a tool that's hard to use with a keyboard or screen reader, let us know and we'll prioritise the fix.

How to report an issue

Email us through the Contact page with:

  • The page URL (e.g. https://utilitiesbunker.com/tools/json-formatter)
  • What you were trying to do and what happened instead
  • Your device + browser (and assistive tech, if any — NVDA, JAWS, VoiceOver, TalkBack)
  • Optional: a screenshot or short screen recording

Compatibility

We test on current versions of Chrome, Edge, Firefox, and Safari, on both desktop and mobile. If something behaves differently in your environment, please reach out.

Continuous improvement

Accessibility is an ongoing process. As we add new tools and categories, we test each one against keyboard and screen-reader navigation. Fixes go out as soon as they're identified — see the changelog for recent work.
