URL Encoder
Why Encode URLs?
URL encoding converts characters into a format that can be transmitted securely over the internet. URLs can only be sent over the internet using the ASCII character set. Since URLs often contain characters outside the ASCII set, the URL has to be converted into a valid ASCII format. URL encoding replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.
About the URL Encoder & Decoder Tool
Safely encode URLs to ensure special characters are transmitted correctly over the internet, or decode percent-encoded URLs back into readable text.
How to Use
Paste your URL or text string into the tool. Click encode to convert special characters into percent-encoding (e.g., space becomes %20), or decode to reverse the process.

Frequently Asked Questions
Does this tool encode spaces as %20 or +?
It natively encodes spaces as
%20, adhering to the modern RFC 3986 standard for maximum compatibility across all web servers and APIs.What's the difference between encodeURI() and encodeURIComponent()?
In JavaScript,
encodeURI() is meant for full URLs and leaves characters like ? and / intact. This tool uses encodeURIComponent(), which encodes almost all special characters, making it the perfect method for safely placing a value inside a URL query parameter.Why did my decoded URL lose its plus signs?
In legacy query strings,
+ is often used to represent spaces. When decoding, the tool may translate them back to spaces depending on the context.
