About URL Encoder / Decoder

URL encoding (also known as percent-encoding) converts characters into a format that can be safely transmitted over the Internet within query parameters.

Frequently Asked Questions

Why do URLs need encoding?

URLs can only be sent over the Internet using the ASCII character set. Special characters like spaces, question marks, and ampersands must be encoded.

Is URL encoding case-sensitive?

Percent-encoded characters (like %20) use hexadecimal digits where letters can be uppercase or lowercase, though uppercase is standard.
