URL Encoder / Decoder

Safely construct robust web addresses by encoding special characters in your URLs with standard percent-encoding (like %20 for spaces). Alternatively, paste messy encoded strings to instantly decode them back to readable human text. The tool simultaneously supports both full `encodeURI` operations and stricter `encodeURIComponent` functions for query parameters.

How It Works

Paste your raw text or existing URL into the primary input field. Select the toggle between 'Encode' or 'Decode' operations. Choose your desired strictness level (Component vs Full URI), and the resulting string will instantly update below.

Frequently Asked Questions

What exactly is URL encoding? ▾

Also known as percent-encoding, it's a mechanism to safely pass data across the internet. It replaces 'unsafe' characters with a `%` symbol followed by their two-character mathematical hex code. For example, a blank space becomes `%20` and an ampersand `&` becomes `%26`.

What is the difference between encodeURI and encodeURIComponent? ▾

`encodeURI` is used for full URLs, preserving structural characters like `:`, `/`, `?`, and `#`. `encodeURIComponent` is far more aggressive, encoding absolutely everything. It is designed specifically to ensure query parameter string values don't break the parent link.

Are my pasted links tracked? ▾

No. The entire conversion execution runs directly inside your active browser utilizing native Javascript functions. The data never interacts with an external server.
