URL encode/decode

Percent-encode a URL or query string, and decode encoded URLs back to readable text.

Anything you type or paste stays in your browser — it is not uploaded to Tools99.

How this workspace works

Paste a URL or query string to encode, or an encoded one to decode.
Run the conversion.
Copy the readable or encoded result.

URL Encode / Decode

Full-URL mode (encodeURI, keeps : / ? & =)

Your text never left this browser, so there is no server copy to delete. Copy it again, start over, or continue with a related tool below.

How to use URL encode/decode

Paste a URL or query string to encode, or an encoded one to decode.
Run the conversion.
Copy the readable or encoded result.

A good use for this

Making a link with spaces or special characters safe to paste, or reading back an encoded link you received.

Limits

Encoding changes how a URL looks, not where it goes — an encoded link to a bad destination is still a bad destination. Check the decoded address before clicking.
