Frequently Asked Questions
URL encoding (percent-encoding) converts characters that are not allowed in URLs into a % followed by two hex digits. For example, a space becomes %20, and & becomes %26.
encodeURIComponent encodes all special characters including /, ?, &, =, # and more. encodeURI preserves characters that are valid in a full URL (like /, :, ?, &). Use encodeURIComponent for individual parameter values and Full URL mode for complete URLs.
In HTML form submissions, spaces are sometimes encoded as + (application/x-www-form-urlencoded). In standard URL encoding (percent-encoding), spaces are encoded as %20. This tool uses %20.
You need to URL-encode when passing special characters in query parameters (e.g. search terms with spaces, accented letters, or special symbols like &, =, #). Without encoding, these characters can break your URL.
