URL Encoder / Decoder
Encode special characters in URLs to make them safe for transmission.
How URL Encoder / Decoder Works
URL Encoding (Percent-encoding) converts characters into a format that can be transmitted over the Internet. It replaces unsafe ASCII characters with a "%" followed by two hexadecimal digits.
Use this tool to clean up query parameters, prepare data for API requests, or debug encoded URLs from server logs.
Frequently Asked Questions
Which characters are encoded?
Reserved characters (like /, ?, :, @) and unsafe characters (like spaces, quotes, <, >) are replaced with their percent-encoded equivalents.
What is the difference between encodeURI and encodeURIComponent?
This tool uses `encodeURIComponent`, which encodes strictly everything, including / and ?, making it safe for query string values.
Can I decode complex nested URLs?
Yes, but you may need to click "Decode" multiple times if the URL was double-encoded.
