URL Encoder & Decoder
Encode text and web links into percent-encoded URL formats or decode encoded URI components back to readable plain text with live input conversion.
encodeURIComponent()
Encodes everything — safe for query params
encodeURI()
Preserves URL structure (scheme, host, path)
Code Snippets & Examples
Copy-paste ready code implementations for your project:
// Encode query parameter
const param = encodeURIComponent('hello world & test=100%');
// Decode
const raw = decodeURIComponent(param);from urllib.parse import quote, unquote
encoded = quote('hello world & test=100%')
decoded = unquote(encoded)⚡Related Developer Tools

Frequently Asked Questions
What is URL encoding?
URL encoding (also known as percent-encoding) converts characters into a format that can be transmitted safely over the Internet in URLs. Unsafe characters are replaced with % followed by two hexadecimal digits.
What is the difference between encodeURI and encodeURIComponent?
encodeURI preserves special URL syntax characters like :, /, ?, # so the full URL remains valid. encodeURIComponent encodes ALL special characters including :, /, ?, # so the string can be safely passed as a single query parameter value.
