URL Encoder and Decoder
Encode URLs when reserved or unsafe characters need to be represented correctly inside query strings, tracking parameters, redirect targets, form values, or other URL components, and decode encoded strings when you need to inspect the readable value. Use encoding on the specific component that requires it rather than blindly encoding an entire address, because separators and delimiters can change meaning when transformed. After decoding, verify the resulting characters before reusing the value in redirects, analytics workflows, or application logic, especially when nested parameters or repeated encoding may be involved.
