Online URL Encoder & Decoder

Encode or decode URLs instantly. This tool converts special characters (like spaces, slashes, and emojis) into their percent-encoded equivalients (e.g., %20) so they can be safely transmitted over the internet.

Unlike simple converters, RootUtils includes a powerful Deep Inspection engine. It automatically parses query parameters and detects hidden data formats like JWTs, Base64 strings, and Unix Timestamps embedded within your URLs.

Param Parser

Paste a long, messy URL, and we will extract every query parameter into a clean list. We even decode nested JSON objects found inside params automatically.

100% Private

URLs often contain sensitive session tokens or API keys. This tool runs entirely in your browser using JavaScript. Your data is never sent to our servers.

UTF-8 Ready

We handle multi-byte characters correctly. Encode URLs containing Chinese, Arabic, or Emojis without corrupting the data.

Developer Guide: encodeURI vs encodeURIComponent

encodeURI (Full URL)

Use this when you want to encode a complete URL. It preserves special characters that have meaning in a URL, like : / ? # & =.

Input: https://site.com/a file 
Output: https://site.com/a%20file

encodeURIComponent (Part)

Use this for values inside parameters. It encodes everything, including slashes and question marks, so they don't break the URL structure.

Input: ?q=a&b 
Output: %3Fq%3Da%26b
