What is URL encoding?

URL encoding (percent-encoding) replaces special characters with a % followed by their hex code — for example, a space becomes %20 and & becomes %26. This is required for characters that have special meaning in URLs.

What is the difference between Encode and Encode Full URL?

Encode (encodeURIComponent) encodes everything including /, ?, =, and & — use this for query parameter values. Encode Full URL (encodeURI) leaves the URL structure characters intact, encoding only unsafe characters.

When should I use URL encoding?

Encode query parameter values before appending to URLs, when passing URLs as parameters, or when embedding special characters in href attributes. Always decode before displaying or processing.

Does this work with unicode characters?

Yes — non-ASCII characters like emoji and accented letters are first UTF-8 encoded and then percent-encoded, producing the correct result for modern URL standards.

How to URL Encode / Decode

Paste your text or URL into the input area.
Click "Encode Component" to encode query parameter values (encodeURIComponent).
Click "Encode Full URL" to encode a complete URL while preserving its structure (encodeURI).
Click "Decode" to reverse percent-encoding back to the original string.
Use "Swap to input" to move the output back for further processing.

Why Use This Tool?

URL encoding is essential when working with web APIs, building query strings, or handling user-submitted data in URLs. This tool makes it easy to encode and decode URL components without writing code, with a quick reference table for the most common encoded characters.
