Frequently Asked Questions
What is URL encoding?
Converting characters unsafe in URLs to percent format — space becomes %20, & becomes %26.
When should I encode a URL?
Before using user input as a query parameter value, or when a URL contains special or Unicode characters.
Is URL encoding the same as Base64?
No — they are different encoding schemes for different purposes.
Is my URL data safe?
Yes — all encoding/decoding runs in your browser. Nothing is sent to a server.
Does it handle full URLs or just parameters?
Both — encode an entire URL or just individual query parameter values.
