❓ FAQ
Q: What is Base64 encoding?
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data in emails, URLs, and web applications.
Q: When should I use Base64 encoding?
Base64 is useful when you need to transmit binary data over text-based protocols, embed images in HTML/CSS, or store complex data in formats that only support text.
Q: Does Base64 encoding encrypt data?
No! Base64 is an encoding method, not encryption. It makes data unreadable to casual observers but can be easily decoded by anyone. Don't use it for sensitive data without proper encryption.
Q: Can I encode special characters?
Yes! Our Base64 encoder fully supports UTF-8, so you can encode any Unicode character including emojis, Chinese characters, and special symbols.
