Häufige Fragen

What is URL encoding?

URL encoding (also known as percent-encoding) is a mechanism for encoding unreserved characters in a Uniform Resource Identifier (URI) under certain circumstances. It converts unsafe characters into a format that can be transmitted over the Internet.

Why do I need to encode URLs?

URLs can only contain a limited set of ASCII characters (alphanumeric and some special characters). If a URL contains characters outside this set (like spaces, accents, or symbols), it must be encoded to ensure the browser interprets the address correctly and the server receives the data as intended.

Which characters are replaced during encoding?

Generally, any character that is not in the 'unreserved' set (A-Z, a-z, 0-9, hyphen, underscore, dot, tilde) is replaced. Common replacements include spaces becoming %20 or +, slashes becoming %2F, and question marks becoming %3F.

How does the tool handle spaces?

The standard for URL encoding replaces a space with %20. However, in the query string part of a URL (application/x-www-form-urlencoded), spaces are often represented by a plus sign (+). This tool typically uses the standard %20 format unless specified otherwise.

Does this tool support UTF-8 characters?

Yes, this tool encodes characters using UTF-8 byte representation. For example, the Euro symbol (€) is converted into three encoded bytes: %E2%82%AC.

What is the difference between encoding a component vs. the full URL?

When encoding the full URL, characters that have special meaning in the URL structure (like /, ?, &, =) are also encoded. When encoding a specific component (like a query parameter value), you typically want to leave those structural characters unencoded. This tool encodes the entire string provided.
