Prohibition Symbol - Red Circle with X Icon for Web and UI Design #3521880 (License: Personal Use)

This image displays a classic prohibition symbol: a thick red “X” centered within a bold red circular outline, set against a transparent checkerboard background indicating alpha transparency. The design follows international standards for visual warnings, ensuring high visibility and immediate recognition. It is commonly used in digital interfaces, signage, and safety documentation to denote restriction, cancellation, or invalid status.

This icon is typically used in web forms, mobile apps, and software interfaces to signal errors, disabled actions, or prohibited operations. It matches user intent when they need to understand that an action cannot be performed, a field is invalid, or access is denied.
