Frequently Asked Questions
- What is the difference between URL encoding and URI encoding?
- They are essentially the same concept. encodeURIComponent() (used here) encodes all characters except letters, digits, and - _ . ! ~ * ' ( ). Use it for individual URL components like query values.
What is URL Encoder / Decoder?
A URL encoder/decoder converts text to and from percent-encoding (also called URL encoding), which is the format required for safely including special characters in URLs. Characters outside the unreserved set (letters, digits, -, _, ., ~) must be percent-encoded using their hexadecimal code points prefixed by %. For example, a space becomes %20, & becomes %26, and = becomes %3D. URL encoding is essential when constructing query strings, embedding user input in URLs, working with REST API endpoints that accept special characters in parameters, encoding redirect URLs, and processing form data submitted via HTTP GET requests. The decoder reverses the process, converting %XX sequences back to their original characters.
