About URL Encode/Decode

What is URL encoding?

URL encoding (also called percent-encoding) is the process of converting characters into a format that can be safely transmitted in a URL. Characters outside the unreserved ASCII set (letters, digits, hyphen, underscore, period, tilde) are replaced with a percent sign followed by two hexadecimal digits representing their byte value. For example, a space becomes %20, '&' becomes %26, and '=' becomes %3D.

When is URL encoding necessary?

URL encoding is required whenever you include user-generated data in URLs: query parameters, path segments, fragment identifiers, and form submissions with GET method. Without encoding, characters like &, =, ?, and # would be misinterpreted as URL structure delimiters rather than data values. Our tool supports both encoding (text to percent-encoded) and decoding (percent-encoded back to text).

Developer use cases

Developers need URL encoding when constructing API request URLs with dynamic parameters, building OAuth callback URLs, generating shareable links with embedded data, debugging encoded URLs in server logs, and handling internationalized URLs with non-ASCII characters. Proper URL encoding prevents broken links, parameter injection, and data corruption in web applications.
