Frequently Asked Questions
Why is URL encoding necessary?+
URL encoding converts reserved characters (like spaces, &, ?, /) into safe percent-encoded ASCII representations so browsers and servers can parse query strings safely.
Is my text kept private?+
Yes. Processing occurs strictly in local JavaScript in your browser.
Should I encode an entire URL or only its parameter values?+
Usually encode individual query parameter values so structural characters such as colons, slashes, question marks, and ampersands keep their URL meaning.
