What is URL Encoding?

URL encoding converts spaces and reserved characters into a safe format that can be used inside URLs. This prevents query parameters from breaking when they contain symbols, punctuation or non-standard characters.

Developers use URL encoding for API requests, redirect URLs, search parameters, OAuth flows, tracking links and form submissions.

Frequently Asked Questions

What characters need URL encoding?

Spaces, ampersands, question marks, slashes and other reserved characters often need encoding when used as values.

Should I encode the whole URL?

Usually you encode parameter values, not the entire URL structure.

Why did my query string break?

An unencoded ampersand or equals sign inside a value can be interpreted as a parameter separator.
