Common questions about URL encoding and percent encoding
URL encoding (percent encoding) converts special characters like spaces, ampersands, and non-ASCII characters into a format safe for URLs. You need it when passing user input as query parameters, handling file names with spaces, or working with international characters in URLs.
encodeURIComponent encodes everything except letters, digits, and - _ . ~ — use it for query parameter values. encodeURI preserves URL structure characters like :, /, and ? — use it for full URLs. Our tool supports both modes.
Spaces are encoded as %20 in URL paths (RFC 3986) and as + in query strings (HTML form encoding). Our tool handles both standards. Most modern APIs expect %20, while legacy HTML forms use the + convention.
Unicode characters are first converted to UTF-8 bytes, then each byte is percent-encoded. For example, 'é' becomes %C3%A9 (two bytes). Emoji like 🎉 become four percent-encoded bytes. Our tool handles the full Unicode range.
Yes. Missing or double-encoding can lead to URL injection, open redirect vulnerabilities, and cross-site scripting (XSS). Always encode user-supplied values before inserting them into URLs, and decode exactly once on the receiving end.
All encoding and decoding happens locally in your browser. No data is sent to any server. You can safely encode URLs containing API keys, tokens, or sensitive parameters without any privacy concerns.
