Percent-encode a URL or decode one back to readable text. Spaces become %20, accents and reserved characters are escaped, and encoded links are decoded in a click. You can also break a full URL into its query parameters for easy reading.

How it works

Paste the link or text into the input — the encoded result appears below immediately.

Choose Decode to turn percent-encoded strings into readable characters.

When the input looks like a URL, each query parameter is listed separately.

Examples & Data

Plain	Encoded
hello world	hello%20world
café & crème	caf%C3%A9%20%26%20cr%C3%A8me
a=1&b=2	a%3D1%26b%3D2

Notice that & and = are escaped when they are part of a value, not a separator.

Frequently Asked Questions

A way to represent characters that are not allowed in URLs using a % sign followed by two hex digits, such as %20 for a space or %C3%A9 for é.

No. Encoding only makes the URL valid — it is not encryption and hides nothing. Never put secrets in a URL.

Use it for the values of query parameters. Reserve encodeURI for a whole URL where structure characters like / and ? must stay intact.
