URL Encode
Percent-encode any string for safe use in URLs and query parameters.

URLs reserve certain characters (?, &, =, /, #, space) for syntax. Any value embedded in a URL — query parameter, path segment, fragment — must percent-encode those characters. Converterzilla's URL encoder applies the equivalent of JavaScript's encodeURIComponent locally: emoji, accented characters, and special syntax characters are all handled correctly.
How to use URL Encoder in your browser
- Paste your string. Type or paste the value you need to URL-encode.
- Read the encoded form. Live updates as you type.
- Copy. Drop the encoded string into your URL or API call.
Why use Converterzilla for URL Encoder
Component-level encoding
We use encodeURIComponent semantics so '&' and '=' are escaped — safe for query-string values.
UTF-8 correct
Multi-byte characters encode as the right %XX%XX sequence.
Local execution
No tracking, no server round-trip.
Frequently asked questions about URL Encoder
encodeURI is for whole URLs (keeps ':/?#&=+' intact); encodeURIComponent is for individual values (encodes those too). We use the latter — it's almost always what you want.
