URL Encoder / Decoder
Free URL encoder and decoder. Encode or decode URL-safe strings with percent-encoding support.
How the URL Encoder / Decoder works
URL encoding replaces unsafe or non-ASCII characters with a percent sign followed by their UTF-8 byte values in hexadecimal (e.g., a space becomes %20). Reserved characters like ?, &, and = are also encoded when they would otherwise be interpreted as URL delimiters. Decoding reverses this process.
