URL encoder

Type or paste text and see it percent-encoded below, ready to go into a URL as a query value or a path segment: spaces become %20, and every character that means something in an address is encoded.

One value at a time

Encoding is meant for one value, such as a query parameter or a path segment, so / ? & = # and + are encoded too. Encode each value on its own, then join them with & and =.

Any character

Letters beyond ASCII, such as é or 日本, and emoji are written as their UTF-8 bytes (é becomes %C3%A9), which every server reads.

JSON in a parameter

Paste JSON to put it into a query parameter. It is encoded as written, so Minify it first for a shorter address.

Encoding a whole address?

To make a full address safe, encode only the values of its query parameters and keep the rest as it is. Encoding the whole address turns its :// and / into %3A%2F%2F and %2F, and it stops working as a link.

Questions

Is a space %20 or +?

Encode writes %20, which means a space everywhere in a URL. A + means a space only in query strings and forms.

Is my data uploaded anywhere?

Your documents aren't: everything runs in your browser, and they are saved on your computer, in the browser's storage for this site. With your permission we count anonymous visits, never their content.
