How it works

This tool checks whether your input is already a full Data URL or a raw Base64 string. If the input is raw Base64, it wraps the value in a valid image Data URL so the browser can render it directly. When the string is valid, the decoded image preview appears immediately and can be downloaded.

Examples

  • Raw Base64: iVBORw0KGgoAAAANSUhEUg... → preview rendered as a PNG image
  • Data URL: data:image/jpeg;base64,/9j/4AAQSkZJRg... → preview rendered using the included MIME type
