Free Online URL Encoder & Decoder
Sanitize webpage links by encoding special characters, or decode encoded URL query parameters instantly.
Sanitize Webpage Links Instantly
URLs can only contain standard alphanumeric characters and a few safe symbols. Special characters like spaces, question marks, and ampersands have functional meanings. To transmit these characters in query parameters safely, they must be converted into percentage-encoded representations.
Our free online URL encoder and decoder handles link sanitization locally, protecting your query data.
What is Percent-Encoding?
Percent-encoding converts non-ASCII characters into a "%" followed by their hexadecimal representation:
- Spaces: Become "%20" or "+".
- Ampersands (&): Become "%26" (which prevents breaking query parameter chains).
- Slashes (/): Become "%2F" (preventing route matching conflicts).
