What Is URL Encoding?
URL encoding (or percent-encoding) is a mechanism for converting special characters, spaces, and reserved symbols into a format that can be safely transmitted in URLs. It's essential for creating valid URLs that work across different browsers, APIs, and systems.
For example, a space is encoded as '%20' and a question mark is encoded as '%3F'. Our URL Encoder/Decoder makes this process simple.
How to Encode a URL
To encode a URL, select the Encode mode, paste your text or URL parameter, and the tool will convert all special characters to percent-encoded format.
This is useful for preparing query parameters, API requests, and OAuth callback URLs.
How to Decode a URL
To decode a URL, select the Decode mode, paste your percent-encoded string, and the tool will convert it back to readable text.
This is useful for debugging encoded URLs, inspecting API parameters, and reading tracking links.
URL Encoder for Developers
Developers use URL encoding when building API requests, working with query parameters, and handling authentication redirects. Our tool helps you quickly encode or decode URL components during development.
It follows JavaScript's encodeURIComponent standard, ensuring compatibility with modern web applications.
Common Use Cases for URL Encoding
URL encoding is commonly used for: query parameters (e.g., search queries, filters), OAuth and authentication redirects, tracking links, and encoding data in API requests.
Without proper encoding, special characters can break URLs and cause errors. Our tool ensures your URLs are safe and valid.
Is URL Encoder Private?
Yes. All URL encoding and decoding happens locally in your browser. Your data is never sent to a server.
This makes our URL Encoder safe for handling sensitive data, API keys, and authentication tokens.
