Free Online URL Encoder and Decoder
The Versatools URL Encoder/Decoder converts text to and from URL-safe percent-encoding format. URLs can only contain a limited set of characters, so special characters must be encoded before being included in a URL. Our tool handles this conversion instantly and accurately.
Why URL Encoding is Necessary
URLs can only contain alphanumeric characters and a few special characters. Any other character must be percent-encoded, which replaces the character with a percent sign followed by its hexadecimal ASCII code. For example, a space becomes %20, an ampersand becomes %26, and a question mark becomes %3F. This ensures URLs are transmitted correctly across the internet.
Common URL Encoding Scenarios
Developers need URL encoding when building query strings with dynamic values, passing special characters in GET parameters, encoding file names for download links, and constructing API request URLs. URL decoding is needed when parsing incoming request parameters, reading encoded values from logs, and debugging URL-related issues in web applications.
