URL Encoder and Decoder

How to use it

1. 1Paste a URL or a fragment of one into the box.
2. 2Choose encode or decode.
3. 3Use component encoding for a single query value — it escapes ampersands, slashes and question marks that would otherwise change the URL's structure.
4. 4Use full-URL encoding when you have an entire address and want to keep its separators intact.
5. 5Paste a complete URL to see it split into scheme, host, path and each query parameter separately.

Frequently asked questions

What is the difference between encodeURI and encodeURIComponent?

encodeURI leaves URL separators like slash, question mark and ampersand alone, so it is for whole URLs. encodeURIComponent escapes them, which is what a single query value needs.

Why does a space become %20 sometimes and + other times?

Plus is a form-encoding convention from HTML form submissions, valid in a query string but not elsewhere. %20 is correct everywhere, which is why it is the safer choice.

Why does my decode fail with a malformed URI error?

A percent sign must be followed by two hex digits. A literal percent in text — a discount code, for instance — must itself be encoded as %25 before decoding will work.
