URL Encoder / Decoder

Encode and decode URLs and URI components. Parse URLs into their individual parts.

What is URL Encoding?

URL encoding (also called percent-encoding) is a mechanism for encoding special characters in URLs. Since URLs can only contain a limited set of ASCII characters, any characters outside this set — including spaces, non-ASCII characters, and reserved characters like &, =, and ? — must be encoded using a percent sign (%) followed by two hexadecimal digits. For example, a space becomes %20.

This tool encodes and decodes URLs and URL components, and also parses URLs into their constituent parts (protocol, host, path, query parameters, etc.).

How to Use This URL Encoder/Decoder

Choose your mode — Select "Encode" to percent-encode text, or "Decode" to convert percent-encoded text back to readable form.

Select encoding type — Choose "Component" encoding (for query parameter values) or "Full URL" encoding.

Enter your text or URL — Paste the text you want to encode or the URL-encoded string you want to decode.

View parsed URL — If you enter a full URL, the tool automatically breaks it down into protocol, host, path, and query parameters.

Copy the result — Use the copy button to copy the encoded or decoded output.

Common Use Cases

Building query strings — Encode parameter values before constructing URLs to ensure special characters don't break the URL structure.

Debugging API requests — Decode URL-encoded request parameters and paths to see the actual values being sent.

Sharing links with special characters — Encode URLs containing non-ASCII characters, spaces, or symbols so they work correctly in browsers and messaging apps.

Parsing redirect URLs — Decode nested encoded URLs (like OAuth redirect URIs or tracking links) to see the actual destination.

Frequently Asked Questions

What is URL encoding?

URL encoding (percent-encoding) replaces special characters in a URL with a percent sign followed by their hexadecimal value. For example, a space becomes %20. This ensures URLs are transmitted correctly over the internet.

What is the difference between encodeURI and encodeURIComponent?

encodeURI encodes a full URL but preserves characters like :, /, ?, and # that have special meaning in URLs. encodeURIComponent encodes everything except letters, digits, and a few special characters, making it suitable for encoding query parameter values.

How do I decode a URL online?

Paste your encoded URL into the input field and select "Decode". The tool will convert all percent-encoded characters back to their original form and also parse the URL into its component parts (protocol, host, path, query parameters, etc.).
