URL Encoder & Decoder
Component vs Full URI
Component (encodeURIComponent) encodes all special characters including : / ? & = #. Use this for encoding individual query parameter values.
Full URI (encodeURI) preserves the URI structure and only encodes characters that aren't valid in a URI. Use this for encoding complete URLs.
Frequently Asked Questions
What is URL encoding?
URL encoding (also called percent-encoding) replaces unsafe characters in a URL with a % followed by two hexadecimal digits. For example, a space becomes %20. This ensures URLs are transmitted correctly over the internet.
What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes a full URI while preserving structural characters like :, /, ?, &, =, and #. encodeURIComponent encodes everything, including those characters. Use encodeURIComponent for individual query parameter values, and encodeURI for complete URLs.
When should I URL-encode webhook payloads?
URL encoding is important when sending data as query parameters or in application/x-www-form-urlencoded request bodies. If your webhook uses JSON, you typically don't need URL encoding, but parameter values in callback URLs should always be encoded.
Is this tool safe to use with sensitive data?
Yes. This URL encoder/decoder runs entirely in your browser using built-in JavaScript functions. No data is sent to any server, so your URLs and parameters remain completely private.
