What is Base64?
Base64 is a binary-to-text encoding scheme that converts binary data into an ASCII string format. It's commonly used to:
- Embed images in HTML/CSS as data URIs
- Transmit data over text-based protocols like email (MIME)
- Store binary data in JSON or XML
- Encode credentials for HTTP Basic Authentication
Common Use Cases
🖼️ Data URIs — Embed small images directly in HTML/CSS without separate HTTP requests
📧 Email Attachments — MIME encoding for sending binary files via email
🔑 API Authentication — HTTP Basic Auth encodes credentials in Base64
💾 Data Storage — Store binary data in text-based formats like JSON
