URL Encode Online – Free URL Encoder (Percent Encoding)

URL encoder – Free Online Tool

Our free URL Encoder converts text into a URL-safe format using percent encoding. Spaces, symbols and non-English characters are transformed so your links and query strings work everywhere.

What is URL encoder?

URLs can only contain a limited set of characters. Spaces, ampersands, question marks and characters from other languages must be converted into a percent sign followed by two hexadecimal digits — for example, a space becomes %20.

This process is called URL encoding or percent encoding, and it prevents broken links and incorrectly read parameters.

How to use the URL encoder

1. Paste the text or URL part you want to encode.
2. Click the encode button.
3. Copy the encoded result.
4. Use it in your link, query string or API call.

Frequently asked questions

Why does a space become %20 or +?

%20 is the standard URL encoding for a space. The + sign is used for spaces in HTML form data.

Should I encode the whole URL?

Usually you only encode parameter values, not the full URL with https:// and slashes.

Is URL encoding the same as Base64?

No. URL encoding only replaces unsafe characters, while Base64 converts all data into a different alphabet.
