Url Encode Tool FAQ

What does the Url Encode Tool calculate?

Encodes special characters in a URL so it can be safely transmitted, or decodes it back.

What is URL encoding used for?

URL encoding (percent-encoding) converts characters that are not safe in URLs (spaces, special characters) into a % followed by their hexadecimal code. Required for query strings and form submissions.

Is this tool secure for processing sensitive data?

Encoding/decoding runs in your browser. However, Base64 and URL encoding are NOT encryption — they're encoding formats, not security measures. Don't use them to protect sensitive information.

Is my data sent to a server?

No — calculations run directly in your browser. Your inputs are not stored or transmitted.
