Encode or decode one URL component or form/query value with the matching encoding rules. Encoding does not hide or secure the value. Choose Encode or Decode to transform URL component text. Encoding helps represent reserved characters in a URL; it does not encrypt or sanitize data for every context. This encodes a URL component, not a whole URL for every possible context. It does not make a link safe or hide its contents.

Frequently asked questions
Should I encode a whole URL or one component?
This tool encodes one URL component or form/query value, not a complete URL. Whole URLs have separate structure and encoding rules for their path, query, and fragment.
When should I choose form/query value?
Choose it for values encoded like HTML form data: spaces become +, and + decodes back to a space. Choose URL component for percent-encoded components, where spaces become %20 and + remains a literal plus when decoding.
Does URL encoding encrypt a value?
No. Encoded text is still readable and reversible. Do not put secrets in URLs.
