Frequently Asked Questions

URL encoding (percent encoding) is the process of converting special characters and non-ASCII characters that cannot be used in URLs into hexadecimal codes starting with %. This allows web browsers to correctly interpret URLs.

URL encoding is needed when search queries contain non-English characters, when sending form data, specifying API parameters, or when file names contain special characters. It's essential for web application development.

Spaces, non-ASCII characters, special symbols (&, =, ?, #, +, etc.), control characters, and characters that have special meaning in URLs get encoded. Safe characters (alphanumeric and some symbols) remain unchanged.

Yes, you can use the decode function of this tool to restore encoded URLs to their original format. However, if the encoded string is malformed, an error will be displayed.

The tool can handle long URLs within browser limits, but URLs under 2000 characters are generally recommended. Very long URLs may cause issues with some web servers.
