Free Online URL Encoder / Decoder
Instantly convert strings to URL-friendly format and decode them back.
What is URL Encoding?
URL encoding, also known as "percent-encoding," is the process of converting characters into a format that can be safely transmitted over the internet. URLs can only contain a specific set of characters.
Any special character (like spaces, `?`, `&`, `/`) that is not in this set must be encoded. For example, a space is encoded as `%20`. This tool helps you perform this conversion and its reverse (decoding) instantly.

Why do I need to encode URLs?
You need to encode any data that you pass in a URL's query string. For example, if you want to pass `name=John & Doe` in a URL, the `&` character will be misinterpreted as a separator for another parameter. You must encode it (`name=John%20%26%20Doe`) to ensure the server understands it correctly as part of the name.
Does this tool send my data to a server?
No. All encoding and decoding operations happen entirely within your browser using JavaScript. Your data is never sent to our server, making this tool fast, secure, and completely private.
