What is URL encoding?

URL encoding, also called percent encoding, replaces characters that are unsafe or reserved in URLs with percent-prefixed byte values such as %20 for a space.

Frequently Asked Questions

Is my URL uploaded when I encode or decode it?

No. URL encoding and decoding run with JavaScript in your browser. The text you paste is not sent to Convertr servers.

Should I encode a full URL or a URL component?

Use component mode for query parameter values, path segments and fragments. Use full URL mode when you want to keep URL separators such as : / ? & and = readable.

What does form mode do?

Form mode follows application/x-www-form-urlencoded behavior for query strings, where spaces are represented with plus signs during encoding and plus signs become spaces during decoding.
