Frequently asked questions

Why do I need to encode URLs?
URLs can only contain a specific set of ASCII characters. Reserved characters like '?', '&', '=', and spaces have special meanings. Encoding them (e.g., converting a space to %20) ensures they are treated as data rather than control characters.
What is Percent-Encoding?
Percent-encoding is a mechanism for encoding information in a Uniform Resource Identifier (URI). It replaces non-ASCII or reserved characters with a '%' followed by two hexadecimal digits representing the character's ASCII value.
Does this tool handle UTF-8 characters?
Yes. Our encoder uses modern browser standards to correctly process and encode multi-byte UTF-8 characters (like emojis or non-English alphabets) into valid URL-friendly strings.
Is there a difference between encodeURI and encodeURIComponent?
Yes. encodeURI is meant for a full URL and leaves characters like ':' and '/' alone. encodeURIComponent (used by our tool) encodes every special character, making it perfect for individual parameters inside a query string.
