URL Encoder Decoder: What is URL Encoding and Why It Matters
URL encoding (percent-encoding) is a fundamental concept in web development, ensuring special characters in URLs are transmitted correctly.
What is URL Encoding?
URLs only allow letters, numbers, and a few special characters from the ASCII set. Other characters (Chinese text, spaces, &) must be encoded as % followed by two hex digits.
Example: space → %20, ampersand → %26
When to Use URL Encoding
