Enter any text or URL below to instantly encode special characters for safe use in links and query parameters.
URL encoding converts characters that aren't allowed in a URL — like spaces, ampersands, and special symbols — into a percent-encoded format (such as %20 for a space) that browsers and servers can interpret safely and consistently.
This matters most when building tracking parameters, search queries, or any dynamic value that gets appended to a link, since unencoded special characters can break the URL or get parsed incorrectly.
Use component encoding (encodeURIComponent) when encoding a single value that will be placed inside a query string, like a search term or UTM parameter. Use full URI encoding when encoding an entire URL that should keep its structural characters like ':' and '/' intact.
%20 is the standard percent-encoded representation of a space in a URL path or component. Some systems use '+' as a space specifically within query string values — check which convention your destination system expects.
No. URL encoding is not a security measure — it's purely a formatting step to make special characters safe for transmission in a URL. It provides no confidentiality or protection.
No, as long as it's decoded correctly on the receiving end. Encoding only changes how special characters are represented in transit, not the underlying data itself.
