About URL Encoding/Decoding
What is URL Encoding?
URL encoding converts characters into a format that can be transmitted over the Internet. Only alphanumeric characters and these special characters: -_.~ are safe.
Spaces are replaced with + or %20, and other characters are replaced with % followed by two hexadecimal digits.
When to Encode URLs?
- When including special characters in query parameters
- When passing data in the URL that may contain spaces or symbols
- When creating dynamic URLs from user input
- When working with non-ASCII characters (like é, ü, æ¼¢å—)
Tips & Best Practices
- Always encode user-generated content in URLs
- Decode URLs only when reading parameters
- Encode each query parameter separately
- Use UTF-8 encoding for international characters
