URL Encoding

Free Online URL Encoder. Safe and Secure URL Encoding.


Aspose.HTML provides a free online URL Encoding tool that encodes Uniform Resource Locator (URL) quickly and easily. Using our App, you can encode the URL data that would be transferred and interpreted correctly.

URLs are sequences of characters: letters, digits, and special characters. Since URL often includes characters outside the ASCII set, it has to be converted into a valid ASCII format.

URL encoding, also known as percent-encoding, is a mechanism for converting of characters in a URL into a valid URL format that can be transferred over the Internet. The URL standard can only use a limited set of characters: Latin letters, numbers, and only a few punctuation marks. All other characters need to be encoded. For example, Cyrillic letters, letters with diacritics, ligatures, hieroglyphs should be encoded.

The encoding scheme must be unambiguous, reversible, and provides valid URLs. URL encoding replaces insecure ASCII characters with a "%" followed by two hexadecimal digits. URLs cannot contain spaces. For global interoperability, URLs have to be encoded uniformly. Are you looking for a URL encoding tool? Then this App is made for you! Use our online URL Encoding engine to encode your data.
