What is the difference between the two modes?

Component mode escapes nearly every special character, including / and &; full-URL mode leaves structural URL characters like :, /, ? and # untouched.

Why does a space become %20?

%20 is the percent-encoded representation of a space character, which cannot appear unescaped in a URL.

Does this handle non-English characters?

Yes — non-ASCII characters are encoded as their UTF-8 byte sequence, each byte represented as %XX.

Is my text uploaded anywhere?

No — encoding happens entirely in your browser.

Should I use component mode for an entire URL?

No — that would also encode the :// and / characters, breaking the URL; use full-URL mode instead for a complete link.

Can I encode an email address for a mailto link?

Yes — component mode is a good choice for encoding the subject or body of a mailto: link.

What Is URL Encoding?

URL encoding (percent-encoding) converts characters that aren't safe inside a URL — spaces, ampersands, question marks and non-ASCII characters — into a %XX representation, so the resulting string can be safely used as a URL or query parameter.

This tool offers two modes: component encoding, which escapes everything that would break a single query parameter, and full-URL encoding, which leaves structural characters like : / ? and # untouched so it can safely encode an entire URL rather than just one piece of it.

Astuces

Use Component Mode for Query Values

Component mode is almost always right when encoding a single parameter value.

Use Full-URL Mode for Whole Links

Full-URL mode keeps :, /, ? and # intact so you don't break the URL's structure.
