About URL Encoding

Our URL Encoder / Decoder tool transforms reserved, unsafe, or non-ASCII characters into valid percent-encoded strings (%xx format). This prevents transmission errors and malformed requests when passing parameters through web addresses and APIs.

Everything runs client-side using native browser JavaScript, ensuring your secure tokens and personal query strings never touch an external server.

Frequently Asked Questions

What is URL encoding?

URL encoding (percent-encoding) translates characters into a format that can be transmitted safely over the Internet. Characters outside the ASCII set or reserved characters are replaced with a percent sign (%) followed by two hexadecimal digits.

What is the difference between encodeURI and encodeURIComponent?

encodeURI is used for full web addresses because it leaves characters like slashes (/), colons (:), and question marks (?) intact. encodeURIComponent is designed for query parameter values and encodes all special symbols to ensure safe parsing.

Is my data sent to a server?

No. All encoding and decoding operations happen entirely client-side inside your browser using JavaScript for absolute speed and security.
