FAQ
Why encode URLs?
Certain characters in URLs (spaces, Chinese characters, special symbols) cannot be transmitted directly and must be encoded as % followed by two hexadecimal digits.
What is the difference between URL encoding and Base64?
URL encoding converts special characters to %XX format for URL transmission. Base64 converts binary data to ASCII characters for broader use cases.
How to encode spaces in URLs?
Spaces should be encoded as %20 in URLs, or as + in query string parts. Most modern browsers handle URL encoding automatically.
