Mastering Base64 Encoding & Decoding
Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is widely used in web development for embedding images in HTML/CSS, transferring data in URLs, and ensuring data integrity during transmission.
Common Base64 Encoding Examples
| Plain Text | Base64 Encoded |

| Hello | SGVsbG8= |

Frequently Asked Questions (FAQ)
When should I use Base64?
Base64 is best for small data snippets like icons, small images, or complex strings that need to be passed safely through text-based protocols like HTTP or SMTP.
Is it secure for passwords?
No. Base64 is an encoding, not encryption. Anyone can decode it. Never use it for sensitive security data.
