Why Use a Base64 Encoder?

- Data Sharing: Send binary files safely over email or APIs.
- Security: Add a layer of obfuscation for sensitive information.
- Cross-Platform Support: Base64 strings work across all devices and operating systems.
- Quick Decoding: Use our free Base64 decoder online to reverse the process anytime.
