URL Encoder and Decoder
URL encoding converts characters that have special meaning in URLs into percent-encoded representations so data can be transmitted safely as part of a URL component.
Quick answer
Encode or decode URL components for query strings, paths, and web requests. The core operation is designed for quick browser-based use without an account.
How to use this tool
- Enter a url component or encoded value
- Choose encode or decode

Common errors and things to check
Encode individual components rather than blindly encoding an entire URL. Reserved characters have different meanings in paths and query strings.
Common use cases
- Preparing query parameters
- Debugging redirect URLs
- Inspecting percent-encoded text
