URL Encoder
Encode text for safe use in URLs.
🔗 Encodes special characters for safe use in URLs. Spaces become %20, & becomes %26.
What Is This Tool?
URL encoding (also called percent encoding) converts special characters into a format that's safe to include in a URL. Spaces become %20, & becomes %26, and so on.
Why URLs Need Encoding
URLs can only contain a limited set of characters safely. Characters like spaces, quotes, &, =, and non-ASCII letters have special meaning or aren't allowed, so they must be encoded to travel through the web reliably.
Common Encodings

encodeURI vs. encodeURIComponent
JavaScript has two functions. encodeURI preserves URL-structure characters (/ ? & =) for whole URLs. encodeURIComponentencodes everything, for query parameter values. This tool uses the latter, which is what you usually want.
Frequently Asked Questions
Should I encode the whole URL or just parameters?
Encode individual parameter values, not the whole URL. Encoding the whole URL would break the /, ?, and & that define its structure.
