Frequently Asked Questions
What is URL encoding?
URL encoding (percent encoding) converts unsafe characters into %XX format so they can be transmitted safely in URLs. Spaces become %20, & becomes %26, etc.
encodeURI vs encodeURIComponent?
encodeURI is for full URLs — it preserves :// and /. encodeURIComponent encodes everything, ideal for query parameter values like ?q=hello+world.
Is my data private?
Yes. All encoding/decoding happens in your browser. No data is sent to any server.
