What is URL Encoding?
URL encoding (also known as percent-encoding) converts characters into a format that can be safely transmitted over the internet. Special characters like spaces, ampersands, and non-ASCII characters are replaced with a percent sign followed by their hexadecimal value.
For example, a space becomes %20, and an ampersand (&) becomes %26. This prevents these characters from being misinterpreted as URL delimiters.
Component vs Full URL
encodeURIComponent
Use this for encoding query parameters or path segments. It encodes all special characters including /, ?, #, and &. Best for encoding individual values.
encodeURI
Use this for encoding a complete URL. It preserves URL structure characters like ://?# while encoding other special characters. Best for encoding full URLs.
FAQ
When should I use URL encoding?
