What this tool is for
URLs may only carry a limited set of ASCII characters. Everything else, spaces, ampersands, accented letters, emoji, has to be percent-encoded or the address breaks at the first space. This does that encoding, with the choice between escaping a whole URL or a single parameter value.
How to use it
- Paste the text or URL.
- Pick the mode: component encoding for a single parameter value, URI encoding to preserve the structure of a full address.
- Copy the encoded string.
Frequently asked questions
What is the difference between the two modes?
Component mode escapes reserved characters like & ? = / too, which is what you need for a value going inside a query parameter. URI mode leaves those intact so a complete URL stays a working URL.
Why is a space sometimes %20 and sometimes +?
Percent encoding uses %20. The plus sign comes from HTML form submissions, which use a slightly different rule for the query string. Both are valid in their own context.
