Tips for URL encoding
Encode query values; do not blindly encode the whole URL.
Spaces may be %20 or + depending on the component.
Encode unicode properly (UTF-8 then percent-encode).
Reserved characters differ for path vs query vs fragment.
Verify with the receiving framework’s decoder.
Make text safe for a query string
Processing stays in your browser — your input is not uploaded to our servers.
Encoding replaces reserved characters so a parameter does not split the URL. Use it when building links or form bodies by hand.
Encode the value, not the entire URL including `https://`, unless you really want the scheme escaped.
Encode a URL component
Paste the raw value
Spaces, Cyrillic, and `&` are the usual reasons you need this.
Encode
Copy the result into the query string after `=`.
Do not encode twice
A second pass turns `%` into `%25` and breaks the receiver.
URL encode FAQ
encodeURI vs encodeURIComponent?
This helper is for components (values). Encoding a full URL with a component encoder will escape slashes and `:` too.
Is anything requested?
No. String rewrite only.
Local?
Yes.
