Percent-encoding without guesswork

URLs only allow a limited character set unescaped. Everything else must be percent-encoded.

encodeURI vs encodeURIComponent

encodeURI — for full URLs; preserves :, /, ?, #
encodeURIComponent — for query parameter values; encodes more aggressively

Query string rules

Always encode parameter names and values separately. Never concatenate raw user input into a URL.

Try the URL Encoder / Decoder to verify edge cases like spaces, ampersands, and Unicode.
