What is URL Encoding/Decoding?
URL Encoding (Percent-encoding) is a mechanism for encoding information in a Uniform Resource Identifier (URI). Characters that are not allowed in a URL must be encoded.
When to use decoding?
Often, URLs contain parameters that are encoded (e.g., %20 for space, %40 for @). Use the Decode mode to convert these messy strings back into readable text.
When to use encoding?
If you are sending data via GET parameters in a URL, you must encode special characters to avoid breaking the URL structure. For example, a space becomes %20 or +.
