URL Encoder/Decoder
Encode or decode your text and URLs securely in your browser.
What is URL Encoding?
URL encoding, also known as percent-encoding, is a mechanism for encoding information in a Uniform Resource Identifier (URI). It converts unsafe characters into a format that can be transmitted over the Internet using ASCII characters. For example, spaces are converted into '%20'.
How to use this tool?
Simply paste your text or URL into the input field above. Choose 'Encode' to make it URL-safe, or 'Decode' to return it to human-readable form. Our tool handles standard RFC 3986 encoding.
Is it safe to decode URLs here?
Yes. This tool runs entirely in your local browser using JavaScript. Your input data is never sent to any server.
What happens if the input is not a valid URL?
The tool will still attempt to encode/decode the characters. If a decoding error occurs (like an incomplete % sequence), it will display an error message.
