Accessibility.

The core select–compress–download flow is designed toward WCAG 2.2 AA. It supports keyboard operation, visible focus, labelled controls, status announcements, sufficient text contrast, responsive zoom, and reduced-motion preferences.

Known limits

Image comparison is inherently visual. Essential result information-file size, dimensions, encoder, processing time, and risk-is also provided as text. Automated and keyboard tests do not replace testing with people who use assistive technology.

Feedback before launch

A public accessibility contact method and tested browser/assistive-technology matrix must be added before production deployment.
