URL Decoder

  • What is URL encoding?

    Percent-encoding, or URL encoding, is a method for encoding arbitrary data in a Uniform Resource Identifier (URI) using only the limited US-ASCII characters that are allowed within a URI.

  • What is URL decoding?

    URL decoding is the reverse of URL encoding, converting ASCII-valid characters into more readable characters.

  • What is URL encoding used for?

    URLs (Uniform Resource Locator) can only be sent over the internet using the ASCII character-set, but URLs often contain invalid characters that lie outside what is allowed in the ASCII set. In order to make the URL valid and useable by web browsers, non-ASCII characters in a URL need to be converted into a valid ASCII format.

  • What is URL decoding used for?

    Decoding an encoded URL can help you find and replace errors in your URL causing a hyperlink to break, such as an unwanted or mis-typed character. It also makes your URL more readable, which makes it easier for both people and search engines to process.
