Percent-encode URLs and query parameters for safe HTTP requests or decode encoded web links.
How to Use URL Encoder & Decoder

- Type or paste your link, path, or query string into the input box.
- Optionally toggle 'Encode full URL' to preserve protocol and slashes.
- Copy the processed URL string with one click.
Technical Specifications & How It Works
Uniform Resource Identifiers (URIs) require percent-encoding for characters that have reserved syntactic meanings or are outside standard ASCII ranges.
This utility implements RFC 3986 encoding standards via JavaScript's native encodeURIComponent and decodeURIComponent functions.
Your web links, authorization tokens, and query parameters are processed purely in local browser memory.
Frequently Asked Questions
What is the difference between encodeURI and encodeURIComponent?
encodeURI preserves URL structure characters like ://, ?, and &, whereas encodeURIComponent encodes all special characters for safe inclusion inside query parameters.
Why do spaces become %20 or + in URLs?
%20 is the official RFC 3986 percent-encoding for a space character, while plus signs (+) are traditionally used in application/x-www-form-urlencoded query strings.
Does this tool handle UTF-8 international characters?
Yes, multi-byte UTF-8 sequences such as accented characters and non-Latin scripts are properly percent-encoded.
