Compare Base64 and URL encoding with examples, use cases, and common mistakes.
Updated 2026-05-09
Base64 and URL encoding are often confused because both make text safer for transport, but they are not interchangeable.
| Factor | First option | Second option |
|---|---|---|
| Purpose | Represent bytes or text as a safe alphabet | Make reserved URL characters safe |
| Typical output | aGVsbG8= | hello%20world |
| Security | Not encryption | Not encryption |
Choosing between them
Use URL encoding for URL parts. Use Base64 when data first needs to be represented as text.
Common examples
- Query parameter text
- Data URL payload
- Encoded API field
FAQ
