Helpful FAQ

What does URL encoding do?

It converts spaces and special characters into percent-encoded sequences that are safer inside URLs.

Should I encode a full URL or only part of it?

Usually encode only parameter values or path segments. Encoding a full URL can break separators.

What causes double encoding?

Double encoding happens when already encoded text is encoded again, turning percent signs into encoded characters.

Safe URL Encoding Use

Use encoding when a URL value contains spaces, punctuation, symbols, or non-English characters. Encoding keeps those values from being mistaken for URL syntax. This is especially useful for search queries, redirect parameters, campaign names, and form values.

Do not encode an entire URL unless that full URL is being placed inside another URL as a parameter. In normal links, the protocol, slashes, question mark, equals signs, and ampersands need to remain readable as structure.

After decoding, treat the result carefully. A decoded link may reveal tracking values, redirect destinations, or user-provided text. Do not paste private tokens or sensitive URLs into screenshots or shared documents.
