URL Encoder / Decoder
URL Encoder / Decoder FAQ
What is URL encoding?
It’s a method of converting characters into a format that can be safely transmitted in URLs using percent-encoding.
When should I use URL encoding?
Use encoding when passing special characters (spaces, symbols, unicode) in query strings, parameters, or API calls.
What characters are encoded?
Reserved characters like ?, =, &, %, /, spaces, and non-ASCII characters are replaced with percent-encoded values.
What is the difference between encodeURI and encodeURIComponent?
`encodeURI` leaves URL parts like `?` and `&` untouched, while `encodeURIComponent` encodes everything, making it safer for query parameters.
Is decoding safe?
Yes, decoding simply reverses percent-encoded values back to their original characters. Just make sure the input is valid.
What is URL Encoding?
URL encoding, also known as percent-encoding, ensures that special characters are safely transmitted inside a URL by replacing them with a % followed by their hexadecimal value. For example, ? becomes %3F.
Decoding reverses this process, converting percent-encoded sequences back into their original characters. This is commonly used when processing query strings or API requests.
