URL Encoder & Decoder

What is URL encoding?

URLs may only contain a limited set of characters. Anything else — spaces, accents, emoji, and reserved symbols such as ?, & and / — is written as a percent sign followed by its byte value in hexadecimal. A space becomes %20, and & becomes %26.

Value or whole URL?

Encoding a value escapes the reserved characters too, which is what you want when placing text inside a query parameter. Encoding a whole URL leaves the structural characters alone so the link still works — use it to make an existing address safe without breaking it.

Example

hello world & more encodes to hello%20world%20%26%20more, or hello+world+%26+more with plus-style spaces.
