GUIDE

How to Encode and Decode URLs

Encoding a URL

Select URL Encoder, enter your plain text or web address, and the tool will immediately percent-encode characters like spaces (%20), ampersands (%26), and slashes into safe HTTP parameters.

Decoding a URL

Select URL Decoder, paste an encoded string with % escape sequences, and the tool converts all hex sequences back to readable human text and addresses.

FAQ

URL Encoding Questions

Why do URLs need to be encoded?

URLs can only contain certain ASCII characters. Special characters like spaces, question marks, slashes, ampersands, and non-ASCII letters must be converted to percent-encoded format (e.g. space becomes %20) to prevent breaking web protocols and query parameters.

What is the difference between encodeURI and encodeURIComponent?

encodeURI is designed for complete URLs and leaves characters like http://, ?, &, and / intact. encodeURIComponent is designed for individual query string values and encodes all special characters including slashes and ampersands.

Is any data uploaded to a server?

No. All encoding and decoding are executed locally in your browser using JavaScript's native encodeURIComponent and decodeURIComponent functions.
