What Is URL Encoding?
URL encoding (percent-encoding) replaces characters that are not allowed in URLs with % plus two hexadecimal digits. A space becomes %20 (or + in form data).
Developers use it for query parameters, redirect URLs, API requests, and anywhere special characters must survive HTTP transmission.

URL Encoder FAQ
Is URL encoding the same as encryption?
No. Encoding is reversible and provides no security. Anyone can decode a percent-encoded string instantly. Use encryption (AES, TLS) to protect secrets.
Which mode matches JavaScript encodeURIComponent?
Choose URI component when encoding. It encodes all characters except unreserved ASCII letters, digits,
-._~, matching encodeURIComponent() in JavaScript.When do I use form (+) encoding?
Use form encoding for
application/x-www-form-urlencoded bodies and some HTML form submissions where spaces are represented as + instead of %20.Is my data stored on azrscorp.com?
