URL Encoder/Decoder
Encode or decode URL strings for web development.
About URL Encoder/Decoder
The URL Encoder/Decoder on ToolsOfIndia is a free browser-based tool built for developers, API users and marketers. Encode and decode URLs and URL components, with the tool distinguishing full-URL encoding from component encoding, which handle special characters differently. URLs with spaces, ampersands and Indian-language characters need encoding to work in browsers and APIs, and the tool applies the correct percent-encoding so a link does not break. Developers use it to build a query string, marketers to encode a UTM link, and because everything runs locally, nothing is uploaded. The tool also decodes already-encoded URLs for inspection. It is the URL tool that hand-writing percent-encodings always gets wrong. Being browser-based and offline-capable, it is safe for sensitive values: nothing you type is transmitted or stored anywhere but your own machine. Common scenarios include encoding a UTM link with spaces, building a query string with special chars, and decoding an already-encoded URL. Try it the next time a quick decision needs real numbers behind it.

Frequently Asked Questions
Why encode URLs?
URLs can only contain ASCII characters. Special characters like spaces, &, ?, #, and non-ASCII characters must be encoded using percent-encoding (%xx) for valid URL transmission.
How does URL encoding work?
Characters are replaced with % followed by their two-digit hex ASCII code. Space becomes %20 (or + in query strings), & becomes %26, and # becomes %23.
What is the difference between encodeURI and encodeURIComponent?
encodeURI encodes the full URL preserving characters with special meaning (:, /, ?, &). encodeURIComponent encodes everything including special characters for use in query parameters.
What is the difference between encodeURI and encodeURIComponent?
encodeURI keeps characters with URL meaning like slashes and question marks, while encodeURIComponent encodes everything for a query value.
Do I encode the whole URL or a parameter?
Encode parameters with encodeURIComponent, but the full URL with encodeURI, so the structure stays intact.
