URL Encode
Encode text and special characters for safe use in URLs and web applications.
Overview
URL Encode converts text into percent-encoded format so it can be safely embedded in URLs, query strings, and HTTP requests. Using the same JavaScript encodeURIComponent standard that browsers rely on, it encodes every character except unreserved ones — turning spaces into %20, ampersands into %26, and non-ASCII text into its UTF-8 hex sequence. Because the conversion runs entirely inside your browser, the text you enter never leaves your device, which matters when encoding API keys, tokens, or other sensitive query values.
Common Use Cases
- Building API Query Strings — Developers encoding search terms, filters, or user-supplied values before appending them to a REST API endpoint.
- Debugging HTTP Requests — Backend engineers inspecting or constructing raw HTTP request URLs where special characters must be percent-encoded to avoid parser errors.
- Web Form Parameters — Front-end developers preparing form field values for safe inclusion in GET request URLs or redirects.
- Encoding Sensitive Query Values — Teams encoding tokens or credentials used as URL parameters, with confidence the values stay local and are never transmitted to a server.
- Preparing Redirect URLs — Marketers and developers encoding destination URLs passed as a redirect_uri or return_to parameter in OAuth and SSO flows.
How It Works
Input Your Text
Enter the text or URL parameters that contain special characters you want to encode.
Automatic URL Encoding
The tool converts special characters to percent-encoded format (%20 for spaces, etc.) for URL safety.
Copy Encoded Result
Copy the URL-safe encoded text to use in web applications, APIs, or browser address bars.
