URL Encoder
Encode strings for safe use in URLs. Free, no signup, runs in your browser.
How It Works
Paste any text into the input field and click Encode. Special characters are replaced with their percent-encoded equivalents (e.g. space becomes %20, & becomes %26).
Everything runs in your browser using the native encodeURIComponent function. No server receives your data.
What Is URL Encoding?
URL encoding (also called percent encoding) replaces unsafe characters in a URL with a % sign followed by two hexadecimal digits. This is necessary because URLs can only contain a limited set of ASCII characters.
Common use cases include encoding query parameters, form data, API requests, and any text that needs to be safely embedded in a URL.
