Encode special characters for safe URL usage or decode percent-encoded URL strings back to readable text.
URL encoding (also known as percent-encoding) is a mechanism for converting special characters into a format that can be safely transmitted over the internet. Characters like spaces, ampersands, question marks, and non-ASCII characters are replaced with a percent sign followed by two hexadecimal digits. There are two main types: encodeURI for full URLs (preserving URL structure characters like /, ?, &) and encodeURIComponent for individual URL parameter values (encoding all special characters).
Enter your text or URL in the input field. Click "Encode URL" to safely encode a full URL while preserving its structure. Click "Encode Component" to encode individual parameter values (more aggressive encoding). To decode, paste a percent-encoded string and click "Decode URL" to see the original text.
Our URL encoder is essential for web developers building query strings, API requests, or handling user input in URLs. It handles all edge cases correctly and runs entirely in your browser. No data is uploaded to any server, ensuring complete privacy. Perfect for debugging encoded URLs, constructing safe links, or understanding percent-encoded data.
