What is Base64 Encoding?
Understanding Base64
Base64 is an encoding scheme that converts binary data into ASCII characters. It uses 64 characters (A-Z, a-z, 0-9, +, /) to represent data.
- • Data Transmission: Safely send binary data over text protocols
- • Email Attachments: Encode files for email transmission
- • Web APIs: Include binary data in JSON responses
- • Data URLs: Embed images directly in HTML/CSS
Common Use Cases
- • Image Embedding: Convert images to data URLs
- • API Integration: Send files via REST APIs
- • Configuration: Store binary data in text files
- • Database Storage: Save binary data as text
📝 Example
"Hello World" → "SGVsbG8gV29ybGQ="
💡 Pro Tips
- • Base64 encoding increases data size by about 33%
- • Use for small files; large files are better sent as attachments
- • Perfect for embedding small images in CSS or HTML
- • Many APIs accept Base64-encoded file data
