About Base64 Decoding
Base64 decoding converts Base64-encoded text back to its original binary or text format. This tool automatically detects the type of content being decoded.

- Image Preview: Shows a preview when decoding Base64-encoded images
- URL-safe Mode: Handles URL-safe Base64 (- instead of +, _ instead of /)
- Multiple Encodings: Support for UTF-8, ASCII, and Latin-1 text decoding
- Download Options: Download as text or as the detected file type
